Weird Printing Problems - HELP!

When I go to print on 2 seperate computers, both are returning the error 'The system does not support the command requested'. It does this with EVERY printer I have installed. Also, in the Property Page for each printer, on the Device Settings Tab , half the text is missing and blurry. This is the situation with 2 users, both on NT 4.0 sp 5 and 6. Also, several users are experiencing blue screens (memory dumps) when they try to print. Please help!
