Printer Drivers
General Information ________________
The printer drivers allow you to adjust the settings for your 
print job.  Driver settings can interact with each other.  For 
example, the paper type, weight, and size you use restricts 
many of your job settings.
Changes to driver settings can be 
•used for only a single print job 
•saved as the default settings for ALL print jobs 
or 
•saved (under a name) for future use [only with PCL and 
Macintosh drivers]. 
Install ___________________________
Windows and Macintosh 
See your printed Setup Guide for information on installing 
printer drivers.
The CD(s) supplied with your printer contain:
Drivers      
Color Utilities    
Network Utilities     
Manuals     
NOTE 
Most applications allow the printer properties to be 
accessed from within the document print dialog 
box.
Application settings override driver settings.
Driver settings override printer menu settings.

Which Printer Driver to Use? _________
Windows 
Your printer comes with drivers for 
•PCL 
•Adobe
® PostScript® (PS). 
You can install only one driver, or all of these drivers. 
Your choice depends upon your printing requirements.
PCL 
Choose this if you use TrueType fonts, and you do not 
print PostScript (including “.eps” files) graphics.
This is more efficient and gives good results. 
PostScript 
Choose this if you use PostScript fonts or print 
PostScript graphics. 
Performance is faster. Graphics print at their best 
quality.            
  
If neither driver seems to cover all your needs, you should 
install both drivers. Select the same printer port (LPT1 or 
Network Port) for both drivers during the installation.
Set the driver you plan to use most of the time to be your 
Windows default driver. Most applications allow you to choose 
a different printer from within the print dialog, so you can use 
the alternative driver for printing whenever you need to.  
NOTE 
The line art graphics in this manual are PostScript. 
If you plan to print parts of this manual, choose the 
PostScript driver. Otherwise, the line art graphics print at 
low resolution. The print quality may not be satisfactory.
