Can't Print in a WinXP shared Printer

[AlfredoZ]

Hello all of you Ubunter,
I'm on a Ubuntu Intrepid 64-bit, and im trying to print on a WinXP Pro shared network printer, I looked in every forum, but none of them helps. This is my issue:

1) I open System>Admin>Printers (no prob)
2) Click New>Printer (no prob)
3) Choose "Windows Printer via SAMBA"
4) Choose Navigate..
5) Click "My Network", then "the computer with shared printer", then "The shared printer" (yes, it finds it) , then click "OK".
6) Click "Verify..."
*7) a popup message appears: "Shared Printer is not accessible"

What is going on? Is it the Windows Firewall? if it is, how do i let free access to Ubuntu (what ports, etc)?, if is not, then what is it?

This is my last issue to solve, and its keeping me from migrating to Ubuntu definitly... Please Help! I can't do my HW!

Mi printer is a HP OfficeJet Pro k550 btw.

I also am having this problem. The thing is that it worked fine under Ubuntu 8.04 32bit. No luck, however, with 8.10 64 bit. It's really starting to bug me...
