Colour printing problems

Fri May 10 23:03:00 AEST 1991

I have a Tekronix colour printer 4693DX connected to a Sun 3/160 via a vme
card supplied by Tektronix also. The 3/160 is running SunOS 4.1.1 and
periodically the 3/160 crashes with the following message:

I believe tcpr_of is the tektronix colour printer filter.  As colour print
jobs can come from a variety of Suns on our net it is difficuly to
establish whether a full screen dump, partitial dump is causing the crash.
Tek ar'nt being very helpful telling us we should be using their network
4511 box which connects the  4693DX to the ethernet. ( Only a mere 3K (Uk
pounds)) Here is my printcap; it was setup by the tektronix script:

I am runnig the  latest tektronix software the version number tcpr_version
gives  is:

Has anyone  any ideas what causes this, is a patched version of tcpr
available perhaps ?  Many thanks in advance:
