Setting Up
Commercial Software
The GSX-190 is 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 commands to control these features are different on nearly
every brand of printer. Citizen chose to use the same commands as
the Epson FX-series, and the IBM Proprinter Ill—and then
enhanced these command sets with extra commands that permit
additional print styles, such as reverse {white on black} printing.
Printer drivers in your software are the easiest method for' sending
these commands to the printer; these generally offer support for the
greatest number of printer features.
Other methods are to create your own printer driver, use embedded
printer commands, or set up a group of commands that can be sent
each time the program begins to print.
When you install new software, you are usually asked to select a
driver from a list supplied by the software application. It helps to
know what features some of these drivers offer when you make
your selection. Table 4-1 lists a few of the most common features
associated with Citizen and Epson FX drivers.
