HP LaserJet Printer not allows Printing Multiple Copies

This problem is caused by Mopier Mode being enabled by default. The idea of Mopier Mode is to minimise computer and network traffic by sending only 1 copy to a printer equiped with suitable internal memory. That stored copy is then used to produce the multiple copies. Most HP Laserjets do not have suitable internal memory and so only the one copy sent by the computer gets printed. To disable Mopier Mode:
Click Start

• Click Devices and Printers
• Right click your Laserjet Printer
• Select Printer Properties
• Click the Device Settings Tab
• Scroll down to the bottom
• If necessary, expand Installable Options
• Click on Mopier Mode
• Select Disable in the selection box that appears
• Click Apply

You will now able to print multiple copies. Good luck!
