Printer Drivers and Print Options

This section describes the role of the printer driver and explains how to use
Windows and Mac OS printer drivers for iR C2100/2100S printing.
The term "PostScript" by itself is used to refer to Adobe PostScript
N :
OTE
Level 3 or later. "PostScript" can also refer to Microsoft PostScript.

What a printer driver does

To take full advantage of the features of the iR C2100/2100S, your print jobs
must be sent as PostScript data. Since most applications cannot generate
PostScript data directly, it is the function of a printer driver to interpret
instructions from the application and convert them to PostScript data.
A PostScript printer driver also allows you to select print options specific to
your copier/printer. To do this, the printer driver must be matched with a
PostScript printer description file (PPD) for your iR C2100/2100S. The
PPD contains information about the particular features supported by the
iR C2100/2100S and the copier/printer. The PPD can be thought of as the
lines of PostScript code in the file that are device-specific. When you print a
job, the printer driver lets you choose among features by displaying print
options.
A few PostScript applications can send PostScript data directly to the copier/
printer and present print options within the application interface. Even these
applications, however, require that you use a PostScript printer driver.
