Can't print through local network to printer attached to XP computer.

Hi,

my computer is running Windows 7 Professional.

I have added and installed a shared printer to this computer. The printer is connected to an other computer that is running Windows XP, and the printer is shared.

Everything seems ok. The installation completed without difficulties.
When I am trying to print a test-page, the document shows up in the printer queue for about 30 seconds, saying that the document is being sent to the printer, then it disappears.
Still after 10 minutes nothing has been printed. Nothing happens.

I was almost certain that the problem was the firewall, but I turned off the firewall on both computers and it still doesn't work.

Last year I tried this out with two computers both running XP, and it worked out perfectly.

Does anybody know a solution to this problem?

Hi again,

I found a solution to the problem myself

It turned out to be a double issue.
One of the problems WAS the firewall. I did in the beginning of my troubleshooting try to turn off the firewall, and it didn't work. But that was because there was an other problem as well. I didn't think it was a double problem at that point. So I assumed the firewall wasn't the problem.
I then realised there was only a one way connection between the computers, since the Win 7 pc could access to the XP computer, but the XP computer couldn't get access to the Win 7 computer. I figured out that it was the firewall that caused this issue. Now I could send printing jobs to the queue on the XP computer, but it disappeared from the queue after some seconds and the printer didn't print anything.
The windows troubleshooting on the Win 7 computer couldn't find any problems with the printer connection. Then I downloaded HP's own troubleshooting application from the internet, and it found that it was a driver issue.
Then I did some googling and found a patch for many HP printers for Win 7 x64 (Deskjet 710/720/810/820/1000 Series printers - Patch for 64 ... - HP Support Forum). After applying this patch everything works like a charm.

To summerize:
The firewall was one problem.
And the other problem was that the printer drivers from Windows Update didn't work on Windows 7 x64 (it shouldn't be a problem with the 32 bit version of windows 7).
