I have 2 HP computers, one running Win XP SP3, one running Win7. I have a Lexmark X4270 All-in-One printer attached to the Win7 machine via a USB port. I can print OK from the Win 7 machine, but when I print from the WinXP machine, the print job shows up in both print queues (showing the same number of bytes - which is good!), but then the status gets changed to "Deleting - Sent to printer", and that status shows up in both print queues. The print job then stays there until I do a cancel, followed by a system restart.

FWIW the owner is shown as Guest, but I have permission for Everyone set to print...

I believe I have up-to-date drivers; I don't believe it's a firewall problem. What I would like to see is the Win7 machine's reason for deleting my print jobs - is there a diagnostic tool available?

Also, I notice that the port for this printer on the WinXP machine is set to USB001 - I would have thought something like \servername\sharedprinter would be more appropriate - and I can see that in the list of ports, but the system doesn't let me change the port name from USB001...

Could someone shed some light? I have spent hours on this! TIA

BTW I can do file sharing, no problem!
