[sims] Crashing after every 3rd print

[neonetman]

I've now had two users reporting that when printing either timetables, or class photo sheets, it consistently prints the first 2 jobs correctly, but reports and invalid handle on the 3rd one.

 

This doesn't matter which class/studnet/size of job, but always after trying the 3rd print job

 

Has anyone else come across this, or have any idea what could be causing this

 

Cheers
