Since I installed an Canon iP7270 Inkjet Printer, I get often the error that no printer could be found. In fact, the Sprintspooler has stopped working! How that could be happening? I also have an Brother MFC260C installed on the same computer, now used mainly for scanning because the Printhead works without Cyan now, just fine if set to Gray! On that iP7270 I used all available drivers, started from the automatically installed one by Windows and than all Canon Drivers. Still have many times the problem that the Print Spooler stops. I may could restart the Print Spooler from within the Administrative Tools --> Services but all times. Many times I really need to restart the computer. Anybody has similar problems? Thanks.
