Note
To modify DEVPARAM.PS you should be familiar with the
PostScript setdevparams command. You should know how to
use PostScript dictionaries and key value pairs.
The DEVPARAM.PS Þle lets you conÞgure your printer's serial port. Edit
this Þle before using other Þles to change the printer's performance.
The following example sets ßow control to Xon/Xoff, parity to none, data bits
to 8, stop bits to 2 and the baud rate to 9600. In the example, the changes are
persistent across jobs and across printer power cycles; they remain in effect
until speciÞcally changed again.

Note When you change the settings for the serial port, Switch 4 on the
printer's rear panel must be down for the changes to take effect.
When Switch 4 on the Phaser 220i rear panel is down (Switch 2
up and Switches 3 and 4 down on the Phaser 220e), the default
conditions are these settings: ßow control is Xon/Xoff, parity is
space, 8 data bits, 2 stop bits, baud rate is 9600.
1. Locate the DEVPARAM.PS Þle in the PHSR220 directory on the
Printer Utilities diskette.
2. Copy the Þle to your hard disk.
