Printing problem 8.03.408a

Vantage 8.03.408a Progress

We have a printing problem on one workstation. It will print fine from Vantage all day and then all of a sudden will stop printing. No error message and the system monitor shows the print completed with no errors. Once this happens, nothing in Vantage prints until you exit Vantage and log back in. Once you log back in, all the previous prints that didn't print start to print.

Anyone have any ideas on how to fix this?
