HP Color Laserjet 5550 printing loads of junk pages

Sometimes our HP 5550C printers, which are networked , produce this error:

PCL XL error Subsytem: Userstream Error: MissingData Operator: BezierPath Position: 60225

Then generates 10s ,100s pages of junk paper and we end up with loads of useless paper unless our students tells us.
Any idea on how to tell printer to cancel such prints automatically. We are also using Altman’s PCounter credit system for our printers for our students…
