An Asus P3V4X mainboard, a Canon BJC-5000 printer, Win98SE. To print a document, I have to hit the print button about 4 times. The first 3 times it will give the error that unable to read response from the printer, check to make sure its turned on...yada yada yada. $th time it catches no problem and prints fine. Printer drivers are current. Is maybe the printer port dying?
