I have a HP LaserJet CP3525 usingthe latest PCL 6 driver. After a weekend where the printer has been in sleep mode it will only print one page of a print job on Monday morning then print nothing else until the printer has been power cycled.
Once the printer reboots it prints jobs just fine.
If we let it go to sleep just overnight & try it in the morning it prints just fine. It seems to only exhibit this behaiviour after 2+days of beeing in sleep mode...
