I have a home wireless network that serves a tower PC loaded with Windows XP SP3 and a laptop running Vista Home SP1.
I have a Canon printer that is directly connected to the laptop when it is home and which serves the tower PC thorugh the network.
The printer works fine except that I must re-install it on the tower PC each time I shut down the tower PC and then fire it back up.
Also, even when I cannot print from the tower PC, the printer still shows up in the folder accessible through the control panel. Nor do I get an error message when I send a print command from the tower PC. The printer simply does not print.
There is no event other thans shutting down the tower PC that triggers the problem that I have seen.
