The -120 error is a "directory not found" error that could be related to a
hardware failure on the server. ?If you can print to the LaserWriter IINTX
via the bypass feature of the AppleShare Print Server, then there is a
problem at the server level. It is most important to determine that the
workstations can print to the IINTX on bypass to verify the integrity of
the hardware.
Here are two things to try on the server:
1) If you reinstalled the software over the old files, trash the old files
first and then re-install.
2) Second, consider backing up the server in a file-by-file manner,
re-initializing the drive, and restoring the files. The print server may
be running into some bad sectors which inhibit its ability to spool the
files.
