Tips for Printing on Single Sheets
There are a few things you should know about printing on single
sheets as opposed to continuous paper. When you print on single
sheets, you may notice that your printer prints the first page of your
file correctly but then prints too low on the next page, or that it
prints the last few lines from one page onto the next.
These differences in print position are easy to adjust; you can simply
change some of the settings in your application program as
described below to get the right results.
1.
When you install an application program, it normally asks
you what printer you are using. Make sure you choose the
correct printer. See Chapter 1 for the right printer to choose.
2.
Many programs include an option to set the maximum lines
per page. If your program has a lines-per-page setting and
you are using 8.5x11-inch paper, set the lines per page to
for

If you’re new to ink jet printers, you may wonder how they
differ from dot matrix or laser printers. Two noticeable benefits
of this technology are high print quality and quiet printing.
An ink jet printer produces cost-effective, quality print results.
When you use the right paper, you get crisp, laser-sharp
printouts usually associated with laser printers. And the ink
cartridge inside your printer is easier to replace and more
affordable than the toner cartridges used by lasers.
Inside the ink jet print head, tiny spray units, or jets, draw ink
from the cartridge and then propel them onto the page in the
form of characters or graphics. Because the print head doesn’t
strike the page as it prints, it is much quieter than an impact
printer such as a dot-matrix.

A few precautions
Even if you are familiar with other types of printers, be sure to
read through the following list of precautions to operate your
ink jet printer safely and efficiently:
CI
Under normal circumstances, ink will not come out of the
cartridge. If it does get on your skin, wash it off with soap
and water. If it gets in your eyes, flush them immediately
with water.

0
Keep the ink cartridges out of the reach of children.
Cl
Do not dismantle the ink cartridges or try to refill them.
Ll
Once you install the ink cartridge, do not open the clamp or
remove the ink cartridge except to replace it with a new
one. The cartridge may become unusable otherwise.
CI
Install the ink cartridge immediately after you remove it
from its package. Leaving the cartridge unpacked for a long
time before use may result in poor print quality.

Choosing the right paper
PAUSE
button.
One of the keys to getting great results with your ink jet printer
is selecting the right paper. Paper absorbency is an especially
important consideration. With paper that is too absorbent, the
ink can bleed slightly, causing characters to blur. However,
with paper that is not absorbent enough, the ink may take too
long to dry and smear easily.
The finish and thickness of the paper are also important. Avoid
paper that has a rough finish or a slick, coated finish. Also,
avoid paper that is too thick or too thin. See the paper
specifications in the Appendix for more information.
Most correspondence-quality paper works in your printer
without problems. However, it is a good practice to test any
paper or envelopes in your printer before buying large
quantities.
Setting Up Your Printer
1-3
Page 16
To test a supply of paper, take a single sheet from the package
and load it in the printer. Perform the self test and check the
results. You should test both sides of the paper to determine
which gives you the best quality printing. If the ink does not
bleed or smear, the paper should be suitable for use with your
printer.
Because the drying speed for the ink depends on the pattern
being printed, the type of paper used, and the temperature and
humidity, some smudging or streaking may occur under
certain conditions. If the ink does not dry quickly enough, try
removing sheets one at a time as they finish printing.

Choosing a Place for the Printer
When selecting a location for your printer, follow these
guidelines:
Place the printer on a flat, horizontal, stable surface. If the
printer is tilted or at an angle, it cannot operate properly.
Place the printer close enough to the computer for the
interface cable to reach it easily.
Leave adequate room for easy operation and maintenance.
Avoid using or storing the printer in places subject to rapid
changes in temperature and humidity. Also keep it away
from direct sunlight, strong light sources, or heat
generating devices.
Avoid places subject to shocks and vibrations.
Place the printer where you can easily unplug the power
cord.
Avoid electrical outlets controlled by wall switches or
automatic timers. Also, avoid outlets on the same circuit as
large motors or other appliances that can cause fluctuations
in line voltage.
Keep the entire computer system away from potential
sources of electromagnetic interference, such as
loudspeakers or the base units of cordless telephones.
Use a grounded power outlet; do not use an adapter plug.
If you plan to use a printer stand, follow these guidelines:

Character table
Character tables contain the characters and symbols used by
different languages. The printer prints text with the selected
character table. When you select this feature, the font lights on
the control panel go on or off to indicate the current selection.
Auto print direction
The printer ordinarily prints text bidirectionally for speed and
prints graphics characters unidirectionally for precise vertical
alignment.
When auto print direction is set to on, the printer switches
automatically between bidirectional (for text data) and
unidirectional motion (for graphics data). When this feature is
set to off, the print head motion is controlled by your software.
Network interface mode
If your printer is connected to a single computer, leave this
feature off. If you want to use the printer in a network
environment and share it among multiple computers, set this
feature to on.
When this feature is set to on, data may be present in the
printer’s buffer even though the printer is not continuously
printing. Always make sure the data light is off before turning
off the printer.

Command Summary
Sending printer commands
Most actions your printer performs are handled by your software.
Software commands instruct the printer to print in a particular typeface,
feed the paper a certain amount after printing each line, start printing a
particular place on the page, and so on.
Some software programs let you send these commands yourself. This
allows you to enhance your printing in ways that may not normally be
available through the software. For example, some word processing
programs do not offer italics, but by inserting a command in your
document, you can use italics anywhere you like. The commands your
printer recognizes are listed in this command summary.
How you format commands depends on the software you are using. Some
software programs accept only the decimal format, while others let you
type in ASCII characters. (Some programs don’t let you insert printer
commands at all.) In addition, your software probably specifies certain
punctuation you must use to enter the command. If your software allows
you to send commands to the printer, the software manual should explain
exactly what format and punctuation are required.
Using the command summary
The following section lists and describes all the commands by topic. If a
command has no parameters, it is merely listed. If it has parameters, they
are explained. The parameters are indicated by lowercase letters, usually
n.
The examples below show how the parameters are indicated.
ESC @
is a command with no parameters.
ESC U
l/O is a command that uses 1 to turn the feature on and 0 to turn it
off.
