Printer not responding

[Vladimir James]

I recently upgraded a slot-loading iMac from MacOSX 2 to 3.8. Since 
that time the "Printer is not responding". I have pinged Ethernet with 
positive results, so the problem appears to be the printer. Connections 
are solid, and it prints a test sheet without problems. It worked fine 
previously.

LaserWriter Select 360, Serial adapter/Ethernet connection.
Can anyone offer suggestions on what to try next?
