Vista last page does not print -with print server

I have two vista machines that act the same. I have two samsung ML-2XXX
printer that are acting the same. With the latest print drivers I can print
to the two printers if they are connected to the computers using a hardwire
USB connection. When I try and print to either printer to either printer
using the usb print server output on my netgear wifi router the last page
does not print. The printer comes back with a time out error waiting for the
last page.

Everything works great printing with using the printers connected connected
through this wifi setup if I am using my XP machines.

Anyone know what the problem is with Vist and the last page?

More info:
I can not print one page because it is also the last page.

I can print documents of I add a dummy last page and have the program set to
print one more page than I need.

It seems like Vista is not sending that one last character to allow the last
page to pring.

I have contacted Samsung and HP support several times and they say it is not
their problem.

They say that if their drivers print ok to the USB Port directly there
drivers are good. I agree. Vista should be sending the same informaton to
the usb port as it does over the WiFi?
