After awakening my computer from the Sleep mode, I am not able to print. When I try to print, I get a Canon "Communication Error" message onscreen. However, the error message gives no details. (The printer connects directly to the printer with USB.) So I go over to the printer and unplug the USB cable, and when I do, I hear that sound coming from the computer that indicates that it recognizes that hardware has been disconnected (so I know the computer was at least recognizing that a device was connected). I then plug the USB cable back in, and voila! - I can now print from the computer normally. BUT, when I again put the computer to sleep and awaken it, this whole thing happens all over again.
A few details:
*This problem does not happen when I actually restart the computer. When I restart it, I cna print normally (until I put the computer to sleep and awaken it).
*This hasn't always happened; it just began second months ago, after having had the printer and computer for years. The only thing I can think of that has changed in my computer configuration is that I added a second internal hard drive to my computer several months ago. The printer problem might have begun t around this time, but I don't precisely recall.
*I have installed new printer drivers, but that has not resolved it.
*This doesn't happen with any other USB device.
hasn't always happened, maybe due to second drive
