Macintosh Printing and WinNT

I have a network of Macintosh clients served by an NT server (Macintosh File and Printing Services) all running on TCP/IP and AppleTalk. I have two HP laser printers on the same network which both the NT server and Mac's print to. For quite sometime now, when printing the contents of a Mac folder (directory) to either printer, it will print the contents of the folder starting half way down the physical page sometimes not showing the first few items in the list. It will print the list column headings at the top of the page like it should however. It didn't used to be like this and nothing has dramatically changed on our systems (accept upgrading to newer NT service packs - which could be the culprit). I have tried downloading the latest printer drivers which hasn't helped. As far as I can tell, the printers are set up properly but at the NT level and at the printer level. While this isn't necessarily a problem, it is annoying! Anyone with any ideas?
