Select a different printer driver. If the device PCL 6 printer
driver is selected, switch to the PCL 5 or HP postscript level 3
emulation printer driver, which can be done from a software
program.
Delete all temp files from the Temp subdirectory. Determine
the name of the directory by opening the AUTOEXEC.BAT file
and looking for the statement "Set Temp =". The name after
this statement is the Temp directory. It is usually C:\TEMP by
default, but can be redefined.
