Anonymous printing

In a win 2k Domain environment, I am printing from my workstationand now the job goes to the printer but doesnt print, I check on my PC and I getthe error message, anonymous logon error printing. I have deleted and re-added the printer, it worked fine and all of a sudden I get this error and dont know why.
The person next to me can print to the printer ok and we are both running win 2k workstation
