When your printer is printing ASCII characters instead of the print job you’ve sent, something must be off with your settings.

ASCII is a standard format used between printers and computers that ensures the commands sent to your printer are interpreted and translated to visual text you can understand.

Your printer may print ASCII characters instead of normal readable text if you’ve recently configured your printer settings, have outdated drivers, or your printer firmware is out-of-date.

It is also possible that you’re printing from an application that requires special ASCII character handling or the software itself has compatibility issues with your printer.
