As soon as you see the “The Print Spooler service was started successfully” hit the Yes button on your open dialog box. In the command prompt windows we need to restart the print spooler service through the command “net stop spooler & net start spooler”.More often than not you’ll be prompted that you can’t remove it because it’s in use, regardless of whether it’s in use by a connected printer. Now you would think that being simply clicking that big Remove button shown below would have the desired effect, but no. This will list any and all print drivers that are installed on your local machine. I've found the easiest way to do this is to open an elevated command prompt and type in “printui /s /t2”. The first step is opening up the Print Server Properties UI in admin mode.The long version is where all that athletic training we never got comes into play, because this is 100% a timing issue. The short version of the fix is entering Print Manager, restarting the print spooler, and then just as the print server is starting, backup delete the driver in the instant before the printer is active.

Unfortunately, dealing with the issue isn't as simple as right-click delete, so it's once again time for documentation.

Recently, we've been running into an issue with the Canon drivers getting corrupted by recent Windows 7 updates. The old workplace is a mix of HP printers and Canon copiers that also serve as network printers.
