Glad to read that someone else is spending as much time as me with this problem.
I have a similar situation with 2 G4s running OS10.3.4 with print jobs vanishing & not even previewing from Vectorworks 10.5.1. Yet one other G4 running all the same versions can print with no problems.
I can print some lines and stuff. But anything more complex can't even get a print preview happening.
We have tried the following:
*Tried printing a whole drawing - Progress bar appears for a while, then nothing else happens
*Tried printing a small section of a drawing -Prints OK
*Tried printing to Local and Networked printers - none of them print or can even preview
*Repaired Disk Permissions
*Re-installed the OS up to 10.3.4
*Removed Vectorworks and Vectorworks Prefs and reinstalled up to v10.5.1
*Re-installed the print drivers
*Ran Print Center Repair - no errors detected
*Opened Print Manager - no sign of print job there
*Ran CUPS interface - no sign of print job there
