Windows 7: Cannot print multiple copies on HP LJ Printer

I could not print multiple copies on HP LJ Printer. At first I thought it would be restrictions from PaperCut software. I withdraw the settings to deny any multiple copies print job it still did not work and found the solution from HP website:

1. Select Start, then Printers
2. Right-click the LaserJet   printer icon and select Properties. 
3. Select the Device Settings tab.
4. Find the Mopier Mode and Job Storage settings.
5. Change the settings from Enabled to Disabled.
6. Click Apply and OK.
7. Try to print the job again. It worked like a charm.
