I just upgraded the 3 nw 5.1 sp6 servers to 65sp3 this weekend. The ndps stuff transfered just fine and we can print. However on 3 HP printers, when someone prints a high number of pages it will only print so many then cough up a error. One is 40e102, bad transmission press go. Another was just "stack". The ibm printer we have has printed the same documents no problem. All are going through ndps.

Any ideas?
