I have a Canon i960 printer on a network hosted on a Win XP ver PC. From a Vista 32 bit laptop all works well and we can see the qty of ink left via the status monitor. On the Win 7-64 bit machine, I can print ok but the status monitor opens and reports the printer is not available (or not responding). Any ideas? I have latest driver enhancements installed from Canon on all three PCs. Does the Win 7 block certain network functions that are allowed in Vista?
