Printer error :Unable to open printer (read failure)!
I always could normally print anything via my printer Canon MP260. This printer is connected to the Apple Time Capsule. I print wireless from the imac. Since yesterday it will not print anymore and I get the following error message: Unable to open printer (read failure)!
Try a reset of the printing system. This will require you to add the printer queue again but you will not need to run the driver installation again.
*How to Reset the Printing System*
1. Open System Preferences > Print & Fax
2. Move your mouse over the Printers list
3. Hold down the Control button and click the mouse (or right click if supported).
4. Click "Reset printing system ..."
5. Restart your Mac
Try connecting the printer directly to your Mac via USB to see if you can print. If this works then move it back to the USB of the Time Capsule and try again.
