The -120 error is a "directory not found" error that could relate 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 LaserWriter 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, then re-install.
2) 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.
