The printer prints, but the text is wrong, garbled, or incomplete.
Cause
Solution
If the printer is connected to a computer, the
operating system is malfunctioning.
Check the operating system.
Note
This method works only with Windows 98, NT
4.0, and 2000 operating systems, and the
computer must be connected to a parallel cable.
If you do not know how to use this method, see
the documentation that came with the computer.
Restart the computer. When it beeps during
startup, press F5 and select Command Prompt
Only
. At the C:\ prompt on the computer, type
Dir<LPT1
 and then press Enter. (This assumes
that the printer is connected to LPT1.) If the Go
light comes on at the printer, press 
 (Go) to
print and eject the page. If the page prints
correctly, then the operating system is
malfunctioning.
Font DIMM might be selected but the font DIMM
might not be physically installed in the printer.
(This issue only applies when an Asian-language
font DIMM is installed.)
In the settings for this printer, clear the Font
DIMM
 check box on the Configure tab if no font
DIMM is installed in the printer. Select the Font
DIMM
 check box only if the font DIMM is
physically installed in the printer. If you think that
the font DIMM is installed, make sure that it is
installed correctly.
Solving PostScript (PS) errors
The following situations are specific to the PS language and might occur when several
printer languages are being used.
Note
To receive a printed or an onscreen message when PS errors occur, select this option in the
PS printer driver or the HP LaserJet Toolbox.
The job prints in Courier (the printer default typeface) instead of the typeface you requested.
Cause
Solution
The requested typeface is not downloaded. A
personality switch might have been performed to
print a PCL job just before the PS printing job
was received.
Download the font you want to use and send the
print job again. Verify the type and location of the
font. Download the font to the printer, if
applicable. See the software documentation.
A PS error page prints.
Cause
Solution
The print job might not be a PS job.
Make sure the print job is a PS job. Check to see
whether the program expected a setup or PS
header file to be sent to the printer.
