I installed a new printer on my computer, its running Windows 7 Home Premium. The printer is a Canon MP500 Pixma multifunction. The printer was bought second hand but in perfect working condition. I plugged in the USB cable and the system automatically installed the latest drivers. The printer worked perfectly. The other night my son attempted to print something but the printers status was 'offline'. I thought it may have been a sharting issue but checked and the printer was already shared. I then noted that in the device screen although it showed the printer, it also showed that an 'unknown device' was attached to the computer. This turned out to be the printer. I checked for the latest driver which my computer had already installed. I turned everything off and reconnected everything one by one and when the printer was connected a bubble came up and didnt recognise it stating it was an unknown device. I then uninstalled the printer and started again but the same issue. The device reports error code 43. I have tried other USB ports but no luck and other devices run off the same USB port that the printer was on. I have googled to frustration and cannot seem to find a solution. Am a basic computer user, so plain english (lol) would be appreciated, actually any help at all would be appreciated. I would rather not have to buy yet another printer if I can avoid it. Many thanks and I hope I have included everything I need to in this post, which btw is my very first one!!

No system changes or anything else occured between installation and when the problem occurred, have had the printer 2 weeks and it seemed to work for 1 week. The computer is less than 4 months old and is running the Windows 7 upgrade. No issues at all with it til now (depending of course what the problem is).

Many thanks in advance.

More things I tried, totally reinstalling the drivers, other devices work fine on that USB port, tried in another port, new USB cord didnt make any difference. Fresh install from disc, install from web site, drained power from the computer, multiple restarts etc etc. Just seems odd that the printer worked for a week and then stopped communicating (sounds like an old ex lol) and in my basic knowledge of such things am at a complete loss.

Am astounded!!! after 2 weeks of frustration, countless hours searching for a solution, I finally just unplugged everything, power lead and USB and left it for several hours. I decided to have one more go at this tonight and went to add a printer, and connected everything back up and it reinstalled with no problem at all!!!!! Have even printed something (just to make sure it wasnt my imagination lol). Although on the surface it appears to be 'fixed' am not going to hold my breath lol thanks to all who read this and scratched their heads but for now it appears this problem is solved (watch this space)
