This is not an issue with QuickEMR or Uniprint.
If you see these error codes pop up while trying to print it is a communication error between your computer and your printer or scanner.
The first step is to power down both your scanner and computer. Then turn your scanner on and then your computer. As the computer boots up it will try to reestablish its communication with the scanner.
If this does not work try to up date your scanner driver through your computer.
If this does not work use the set up disc that came with the scanner.
If this does not work contact the manufacturer of the scanner.
