[K12OSN] Laser Printer super-slow?

Could it be a problem with PDFv3? I had an older printer that didn't 
support PDFv3, and each time I would try to print, it would spend a long 
time "thinking about it", and maybe part of the document would print, 
and then the job would fail.

If you're using Adobe Reader to print the PDF, click on the Advanced 
button at the lower left quarter of the Print menu. The Advanced Print 
Setup window will pop up. If Language is set to "Language Level 3", try 
changing it to "Language Level 2".

Something to try, anyway.
