[comp.sys.mac] Laserwriter printing timeout

cosmos@druhi.ATT.COM (GuestRA) (12/16/87)

We are experiencing an error when printing large jobs on our laserwriter
(about 14 pages of viewgraphs).  We are running the latest stuff and
Multifinder with background printing on a Mac II.  PrintMonitor says it got
a timeout (this happens after printing about half of the pages) and
recommends trying again.  However, it tries to start the job over from the
beginning and simply times out again in the same place.  None of the pages
in the vicinity of the timeout have bitmaps.  Anyone know what's wrong and
if it can be cured?  The work around is just to split it into two print
jobs, and that works just fine.

I have experienced this when running programs in the foreground that don't
give up enough time to other tasks under MultiFinder (the Print Spooler being
one of those tasks).  So the Laserwriter times out because it doesn't
get enough data fast enough.  I believe this time constant can be changed
in the LaserPrep file (I'll check) using settimeout or setjobtimeout or
some such.

If you leave PrintMonitor frontmost, it will probably not timeout, but that
isn't much fun now that we finally have background printing.

Actually, the Mac II this happens on is used by our secretary and nothing
else is happening when we tried this print.  MacWrite is "running" in the
foreground, but isn't getting any events (mouse, keyboard, etc.).  So, I
would think PrintMonitor would get enough time.  Is it stil possible that
MacWrite is that ill-behaved even when not doing anything?
