Bit
depth |
 |
|
Each pixel
in an image contains the number of bits
required to save/capture information
about the image. The higher the depth,
the more colors are stored in the image.
Learn more
For example: a low bit-depth (1 bit)
can only show two colors: black and white.
This is because there are only two combinations
of numbers in one bit: 0 and 1. A 4-bit
color image is capable of showing 16
colors, since there are 16 different
combinations of 4 bits:
0000 0001 0010 0011 0100 0101 0110 0111
1000 1001 1010 1011 1100 1101 1110 1111
Also, 8-bit color has the capacity to
show a total of 256 colors; 16-bit color
shows a total capacity of 65,536 colors;
24-bit color can show up to a total of
16,777,216 colors.

Color
Technologies |
|
|
The technology
that an HP Multifunction product (MFP)
or All-in-One (AIO) uses to create color
output. Laser MFPs use vertical tandem
intermediate transfer belt and laser
electrostatic technologies, while Inkjet
AIOs use ImageREt and ColorSmart technologies
created by HP for the best color output. See
Printing Technologies
|
|
Colors |
|
|
In TI DLP
(Texas Instruments Digital Light Processing)
technology, color is produced by passing
light through a color wheel, shining
through the color wheel segments as the
color wheel spins. 16.8 million colors
can be reproduced.
Learn more
After light is passed through the color
wheel, the light is then deflected through
a single TI DLP chip that contains thousands
of tiny mirrors. The light combines on
the screen to produce a colored image.
The colors found in HP digital projectors
have consistent and accurate color because
of the inherent reliability of the DLP
technology. Additionally, HP has created
new color wheel designs, color tables,
and algorithms to provide the optimal
combination of brightness and color to
fit the projection environment and the
content being presented.

|
Connectivity:
Digital Photography |
|
|
The ability
to connect a host computer for image
download using USB cables. HP cameras
are able to connect directly to printers
and camera docks. Some systems may also
include serial or parallel cables for
communications.
|
|
Connectivity:
Projectors |
|
|
The ability
to connect a projector to different source
devices using device-specific cables.
Learn more
HP projectors are capable of connecting
to a variety of devices, such as PCs (Desktop,
Portable, Handheld, and Tablet), DVDs, and
VCRs. The HP xp and vp series products, for
instance, have a large number of input connections
for connecting multiple devices simultaneously
(e.g., PC, monitor, and a VCR for teaching).
Moreover, all HP projectors are smart,
meaning they can adjust brightness, contrast,
color depth, and other image properties
to create the perfect image, regardless
of input device “ automatically,
and without operator assistance.
HP products are tested using various
PCs, DVDs and VCRs, and designed to support
the new TV standards: SDTV (480i), EDTV
(480p), and HDTV (720p and 1080i).
|
|
Connectivity:
Scanners |
|
|
Connecting
a scanner to a host computer using either
a serial, parallel, or USB cable for
communications.
|
|
Copy
Resolution (color/black) |
|
|
The maximum
resolution, measured in dots per inch
(DPI), that an HP Multifunction product
(MFP) or All-in-One (AIO) can produce
on copied documents. Generally, the higher
the DPI, the better the detail and clarity
your copied document will have.
|
|
Copy
Settings |
|
|
The copy
capabilities that an HP Multifunction
product (MFP) or All-in-One (AIO) supports.
Common copy features include fit-to-page,
reduce/enlarge, resolution, contrast,
copy collation, number of copies and
paper size. Color MFPs and AIOs may have
different copy settings for color and
black & white.
|
|
Cost
Per Page |
|
|
The total
cost per U.S letter-sized page with 15%
color coverage or 5% monochrome coverage
including ink, replaceable parts, power,
paper, and average service costs. (The
cost-per-page information provided for
individual printer models is based on
the best information available and is
not guaranteed accurate by Hewlett-Packard
Company. Actual prices may vary.) To
see how HP's cost per page compares to
other vendors, visit the Printer
Comparison Center.
|
|
Dots
per inch (dpi) |
|
|
Dots per
inch has been the traditional measurement
and indicator of a printer's output quality
and refers to how many dots of ink are
placed on each inch of a piece of paper
or other media by a printer. For more
about output quality, see resolution.
|
|
Double-sided
printing |
|
|
See Duplex
Printing.
|
|
Duplex
Printing |
|
|
Printing
on both sides of a page. Auto-duplexing
printers offer automatic double-sided
printing with help from a duplexing accessory
that allows the printer to automatically
output a two-sided page. This feature
makes it easy to print on both sides
of the page without manual intervention
and saves paper.
|
|
Duty
Cycle |
|
|
The maximum
usage level per month for a printer is
the duty cycle. This rating takes into
account printer specifics such as the
paper-handling capacity and cartridge
replacement.
Learn More
Different departments in your company
may have very different duty cycle needs.
Some, like legal and accounting, may
print reams of documents almost daily,
while others like IT may not print much
at all. As you consider your duty cycle
needs, pay close attention to the different
departments that will share the printer
and how much they print monthly. You
may be able to address the light duty
cycle needs of one group with the heavy
duty cycle needs of another in a single
printer or multifunction device, or you
may choose to give each group with high
usage requirements their own printer
to ensure their printing needs are met.
Running a printer regularly at the top
end of its duty cycle causes users to
replace supplies more often, which reduces
their productivity and increases your
supplies usage. You should choose a printer
with a duty cycle that exceeds your current
production needs by a substantial margin
to minimize interventions and maximize
the life of your printer.

Embedded
Media Card Readers |
|
|
Slots built
into an HP printer that allow it to print
photos directly from a memory card. HP
media card readers support most common
memory card formats, including CompactFlash
Type I and II, SmartMedia, Secure Digital,
MultiMedia Cards, Memory Stick, XD, and
USB flash drive.
|
|
Exposure
control |
|
|
Digital cameras
require adjustments to control the levels
of brightness, color saturation, and
contrast in the final image. The factors
that define correct exposure in a charge-coupled
device (CCD) camera are the visible light
spectrum wavelength-dependent sensitivity,
the intensity of illumination, and the
length of time the CCD is exposed to
light.
|
|
Exposure
rating |
|
|
Digital cameras
have an ISO rating indicating their level
of sensitivity to light. ISO 100 is the "normal" setting
for most cameras, although some go as
low as ISO 50. The sensitivities can
be increased to 200, 400, 800, or even
3200 on high-end digital SLR (single-lens
reflex) cameras.
|
|
Fax
PC Interface |
|
|
Support for
faxing from a PC without a physical document
to scan and fax. If you plan to fax a
large number of electronic documents
created on a PC, this feature allows
you to avoid printing the documents before
faxing -- this saves time and consumables.
|
|
First
Page Out |
|
|
The time
it takes a printer to produce the first
page of print job when warming up from
powersave mode. HP Laser printers use Instant-on
Technology to speed the first page
out so you get your complete print job
sooner.
|
|
Focal
range |
|
|
The minimum
and maximum range a camera can focus
on an object. This includes a range from
a moderate wide angle to moderate telephoto.
The ability to lock focus at infinity,
and to set focus manually. Maximum aperture
ranges depend on the lens zoom setting.
Learn more
For example, focus ranges from 1.6 feet
(0.5 meters) to infinity in normal mode, with
a macro setting ranging from 6 to 39 inches
(14 to 100 centimeters); as well as standard
and macro focus modes.
|
|
Hard
Disk |
|
|
A hard drive
for your printer that can store files,
fonts, forms, and other commonly used
data right on a printer, which speeds
the time it takes to print a document.
Some hard drives also make it possible
to protect confidential documents by
holding the document on the drive until
a user physically enters a PIN on the
printer.
|
|
Host-Based
Printing |
|
|
A printing
approach that utilizes the processor
on the PC that is sending a print job
to create the printable pages, rather
than generating those pages on the printer
itself. Printers that utilize host-based
printing can be more cost-effective because
they do not require a powerful processor
of their own. Since HP's host-based printing
solutions utilize the GDI interface that
is built into Microsoft Windows, you
can begin using host-based printing immediately
without investing in additional software.
|
|
|
|
|
Imaging
technology |
|
|
A camera™s
built-in tools for correcting two very
common complaints in point and shoot
photographs: red-eye removal and adaptive
lighting.
Learn more
For example: adaptive lighting option
(which may be available in different strength
settings) simulates the effect of a fill flash
by boosting brightness in shadow areas of images.
Other features may include: HP Real Life
Technologies including In-Camera Panorama
Preview, HP Image Advice, HP Noise Filter,
HP Adaptive Demosiac, HP Vignetting,
and HP Preferred Photo Reproduction.
|
|
Ink
Type |
|
|
The kind
of ink an inkjet printer uses to transfer
a printed image to the page. HP inkjet
and Photosmart printers use pigment-based
inks that penetrate below the paper surface
to provide rich color depth, minimal
dot visibility, and uniform gloss. To
learn more about ink technologies and
HP's innovations in ink, review this PDF
from HP Labs.
|
|
Input
Capacity |
|
|
The number
of sheets of standard printer paper that
can be stored in a printer's paper trays.
Because they do not require constant
refilling, printers with high input capacities
are particularly useful for printers
used by a workgroup or any large group
of people.
|
|
Installed
digital projectors |
|
|
Designed
for permanent placement in conference
rooms and auditoriums with 15 or more
participants and little or no ambient
lighting. A permanent installation typically
includes audio connections to built-in
or permanently affixed high-end sound
systems.
Learn more
HP digital projectors such as the xp8010
and xp8020 series ensure that your messages
are conveyed with crisp, bright, easy-to-read
images and text. Not to mention -- with
the integration of HP color innovations,
these digital projectors will do the
work for you, allowing you to focus your
attention where it needs to be the most:
on your audience.
|
|
Instant-on Technology |
|
|
Cutting-edge
fuser technology that allows HP laser
printers to produce the first page faster
when the printer is coming out of powersave
mode, giving you your complete print
job sooner. Why wait? Learn more about Instant-on
Technology and the benefits it offers.
|
|
Keystone
correction |
|
|
Also called
horizontal and vertical keystone correction;
the most typical adjustment is to vertical
keystone correction. This means that
when an image is projected upwards it
creates a trapezoidal image shape; vertical
keystone correction then squares the
image. If an image is projected from
the side, a combination of vertical and
horizontal keystone correction is required
to square the image. Keystone correction
requires images to be rescaled, which
can have a minor effect on some elements
in the projected image.

Laser
Quality Speed |
|
|
What
is it?
Laser Quality Speed (LQS) is
an HP-developed specification
to enable a speed comparison
of the HP Officejet line of printers
to laser printers, thereby assisting
customer purchase considerations.
The print speed experienced by
customers from an Inkjet printer
is highly dependent on many variables,
including the coverage and content
of the printed document. In contrast,
laser print speed is much less
dependent on document content
and coverage. The Laser Quality
Speed specification helps customers
make a performance comparison
between the print speeds of an
inkjet printer and a laser printer.
How
does it work?
To measure Laser Quality
Speed for an inkjet printing
device, HP prints a representative
suite of documents in the
printer™s default quality
setting (normal mode for
HP Officejet or Officejet
Pro Color Printers and AiOs).
The suite includes several
monochrome & color documents,
including pages of various
text coverage, and full page
graphics and image files.
The speed reporting methodology
averages the print engine™s
black and color speeds, in
pages per minute, by calculating
an average text print speed,
and then averages that speed
with the print speed of a
more complex, full page document.
The resulting average pages
per minute (ppm) speed determine
the Laser Quality Speed specification.
HP™s Laser Quality Speed
measurement process is based
on three important factors:
- Speed measurements use
comparable print qualities.
For the HP Officejet line
of printers and AiOs, the
default plain paper normal
mode is used to generate
the Laser Quality Speed
specification.
- Speed measurements are
done over a range of document
types and content.
- The measurement process
is designed to avoid the
influence of the host PC
performance, and to represent
the printer hardware, or
print engine, performance.
This approach allows a more
direct comparison with published
laser printer ppm speed specifications.
Laser Quality Speed is based
on HP internal testing and
methodology and is not an industry
standard.
Where is
it used?
Laser Quality Speed is used in
product data sheets, customer
education manuals, brochures,
collaterals, and other customer
communications meant to help
customers make purchase choices
between Officejet and laser printers. |
|
|
Light
source |
|
|
The light
source in a projector is derived from
a bulb, also called a lamp. The intensity
of the light is determined by the power
it consumes: a high watt measure (300-watt)
produces a brighter and hotter light.
HP projectors use different size lamps
ranging from 120- to 210-watt lamps.
A lamp has a definitive life-span (measured
in lit hours) and the brightness of the
lamp diminishes over time.
|
|
Maximum
scan size |
|
|
The physical
horizontal and vertical dimension of
an original document or image that can
be scanned based on the size of the scanner.
|
|
Media
Size |
|
|
The sizes
of paper, envelopes, and other media
that a printer's paper trays will support.
The more media sizes your printer supports,
the more flexibility you have in the
types of documents you can print on that
printer.
|
|
Media
Type |
|
|
The various
types of media a printer supports. Beyond
standard office paper, which may include
plain, glossy, letterhead, recycled,
and other standard weight papers, a printer
may also support envelopes, transparencies,
cardstock, labels, and more. It's better
to choose a printer with a wider variety
of media options than to try to force
the printer to print on media it doesn't
support.
|
|
Media
Weight |
|
|
The paper
weights that a printer supports. Paper
weight is determined by the total weight
of 500 pieces of paper. Standard laser
or inkjet paper typically weights 24lb,
while photo papers may weigh 32lb and
higher. The higher the paper weight your
printer supports, the more media options
it will have.
|
|
Memory |
|
|
RAM built
into a print that increases print speed
and helps process large and complex documents.
Maximum memory is the total amount of
memory a printer can accommodate.
Learn More
Memory is an important consideration
on most color printers and for any printer
you plan to share on a network among multiple
employees. For example, a color LaserJet printer
may utilize its memory to speed the printing
of complicated graphics or photographs, making
it easier and more efficient to print color
documents in-house regularly. Similarly, a
shared office inkjet printer might utilize
memory to process several print jobs sent to
it from different employees at one time. This
reduces the time it takes to transfer the print
job from the employee computers to the printer
and helps employees get back to work more quickly.
A printer's maximum memory is the total amount
of memory it can accommodate, and is typically
more than the standard memory that comes installed
on the printer. As you evaluate a printer,
consider how much memory you can add later
as your printing needs change.
|
|
Multitasking
Capability |
|
|
The ability
of a Multifunction product (MFP) or All-in-One
(AIO) to perform multiple functions at
one time. When you choose an MFP or AIO
with this functionality, you can utilize
more than one feature of your device
at one time, which improves productivity
and device utilization.
|
|
|
|
|
Networked/Network-ready |
|
|
An inkjet
or laser printer or MFP that you can
connect to a network and administer from
a Web browser via its built-in Web server.
You can manage all of your networked
printers at once with HP's free Web Jetadmin
software.
Learn More
Many of HP's inkjet and LaserJet printers
and MFPs (multifunction products) are
equipped with HP Jetdirect internal print
servers that allow you to connect the
printer directly to your company's Local
Area Network (LAN) with a standard Ethernet
cable. Once you attach the printer to
your network, all of the users on your
network can share it. It may be less
expensive to purchase a single workgroup
printer to share over the network instead
of several personal printers that won't
be shared. Workgroup printers can typically
provide your employees with more features
than personal printers and you can use
Web Jetadmin -- HP's free print network
management tool -- to conveniently and
easily manage all of your networked printers
from a single location. Learn

PhotoREt |
|
|
A photo resolution
enhancement technology developed by HP
to achieve the highest quality photo
printing results on photo and plain paper
with 289 levels of shade for each color
and a complete palette in excess of 1.2
million colors.
Learn More
Printers equipped with HP PhotoREt technology
uses color layering technology to produce photo-quality
color images. With advancements in its multidrop
color layering process, HP PhotoREt controls
the placement of those six inks more precisely
than before. Each dot is capable of receiving
up to 32 minuscule drops of color, each one precisely
positioned to achieve smoother gradations in
tone and to virtually eliminate any grain in
the printed image. Full dye-load inks in cyan,
magenta, and yellow, produce vibrant color.
Light dye-load inks of light cyan and light
magenta, as well as a specially formulated
dye-based black ink, dramatically increase
the range of available colors, while the black
is richer, deeper, and glossier than the usual
black that is produced by a composite of colored
inks. This means you'll get finer details and
a wider range of colors. The newest generation
of HP color layering technology HP PhotoREt
IV uses six-ink color printing to produce up
to 289 levels of color for than 1.2 million
colors.

your planned projector location to your planned
screen location so you can choose a projector
with the required projection distance capabilities.
|
|
Recommended
Monthly Volume |
|
|
The number
of output pages a printer is designed
to support on a monthly basis. While
exceeding the recommended volume occasionally
poses no problem, regularly exceeding
it can reduce the life of your printer
and compromise print quality. It's better
to choose a printer whose recommended
monthly volume exceeds your current needs
so you have room to grow as your printing
needs grow.
|
|
Scan
