Citizen PROjet II  (260-2957)  Printing With Software  Faxback Doc. # 14704

The PROjet II was designed to work easily with many popular commercial
software packages.  The software is designed to print a file by sending
codes for letters, numbers, punctuation, and so on, in addition to
activating various printer features.  Some commands control rather simple
features, such as ending a line or advancing the paper.  Other commands
control character pitch, font style, fine line spacing increments and
graphics.

The command to control these features are different on nearly every brand
of printer.  By using PCL (Printer Control Language) Level 3+, Citizen made
the PROjet II fully compatible with Hewlett-Packard's DeskJet printers.  In
addition, the PROjet II contains some enhancements to standard DeskJets,
most notable additional fonts.

The easiest way to control your printer from your software is to use the
printer drivers supplied with the software.  When you install the
software, you will generally be asked to select a driver from a list.  To
help you make the best selection, here is a table of drivers and the
features you can expect from them.  As you search through your software
for the appropriate driver, you should look first for the printer mode
listed first below.  If your software does not have a driver for that
model, look for the second model, and so on.

NOTE:  To check that all the features you require are programmed and
       operating correctly, you can run a print test before switching
       to your normal working procedure.

Some software will ask you to define a communication port for your
printing output.  If you are working with a PC, choose "LPT1:", for the
parallel interface.

Incorporated commands

A printer command code is usually a series of otherwise normally printable
characters inserted in the data string sent to the printer.  To make the
printer understand which characters are to be interpreted as command and
which as printable characters, there is a simple convention: all
"characters" that have, according to the character table, a decimal value
less than 32 are interpreted as control codes.  Some of them result in
printer action when they are received, others do not.

There is also a special command ESCAPE (decimal code 27, named ESC) which
is used by most printer emulations to open a command sequence (also known
as ESCAPE sequence).  It is followed by one or more additional characters,
which serve as identifiers and parameters, belonging to the range of
printable characters or control codes available.
