HP Laserjet M600 Printing too many copies

Question:
I work at the Public Library and we currently have an HP Laserjet M602 for printing from public access computers and The printer is networked.  We are experiencing a problem when printing from Office 2010 products.  The printer will print more than one copy of the requested print document.  If more than one print is requested the printer will go crazy and print multiple copies.  The printer will display printing 1 or x number of copies and the only way to stop this is to cancel all the jobs.  We are not seeing the problem when printing from the web browsers.  The driver is HP Laserjet 600 M601, M602, M603 PCL6 HPCM600c Processor is set to WinPrint - Raw Bi-directional support is disabled.   Printer firmware version is 2305090_000468. 
I have previously installed the Universal PCL6 Driver thinking this might been the causing issue but didn't fix the problem.  I need help on this matter before we go broke on paper. 

Thanks you 

Melania

Answer:
We have figured out the root of the cause after much research and testing.  We have concluded the issue is with collate and the print drivers.  Office 2010 and Adobe Reader default settings are to collate.  If more than (1) copy is selected for some reason this would cause the printer to print multiple copies.  We tried the Universal and Standard drivers and the problem continued.  Once we installed the Postscript driver prints the amount of prints requested.  Problem solved.  Thank you.

HP Laserjet M600 Paper Jam Error 59.05.60 

Question:
After printing several pages of a file, the printer display is showing 59.05.60 ERROR.  The display also asks "To continue turn printer off and then on again?"  Even after tuning printer on / off again the error continues to display.  This is getting darn right frustrating

Answer:
The error you are showing is a drum motor error.  I would first try a different toner cartridge.  From time to time this error can be created by the toner cartridge.  If after trying a toner cartridge and  error continues.  Turn the print off and remove the toner cartridge from printer.    Power on the printer, the printer should stop and ask for toner cartridge.    Test the drum motor with the toner cartridge removed go to  -Administration menu -diagnostics menu  -component test -test drum motor.  If the printer errors out in testing drum motor, then drum motor is defective and replace drum motor.  If the motor test passes then the culprit will be the toner cartridge, more than likely the toner cartridge has dezes up.causing the error code.
