Problems printing wirelessly

I have a HP Laserjet 2300. It is connected to my wireless network through a Netgear print server (WGPS606). Recently I added a new computer that uses Windows 7. When I try to print from this computer, it will print the first job or 2 ok, then it starts printing jibberish and blank pages. When everything is turned off and restarted, it will print fine again, for the first 1 -2 jobs, then malfunction again. An older computer on my network, that still has Windows XP pro, does not have this issue. It prints fine. I have uninstalled and reinstalled the drivers for both the print server and the HP Laserjet 2300. Can anyone give me any suggestions on how to fix this problem?
