This can be done by setting the default mode for both ports to be PostScript and then on a per job basis change the mode to be PCL (text). To change from PostScript to PCL, do the following:
1. Put the thumb-wheel selection switch to #1. This sets up both the RS-232 port and the LocalTalk port to PostScript.
2. Append the following PostScript command to the front of a text file.
currentfile /LaserJetIIP statusdict /emulate get exec
Note: The command is case sensitive.
