Word XP prints partial document

User prints Word XP documents with no problems but after having printed a few, the printer starts cutting off the bottom. User reboots and printing returns to normal. The problem is not restricted to one particular document either.

It’s a network printer used by about 6 other people and she is the only one having this problem. It’s a Windows2000 machine with Office XP. The PC has about 16GB of HD free and 256MB RAM. HELP!!!
