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may print ASCII characters instead of normal readable text if you’ve recently configured your printer settings, have outdated drivers, or your printer firmware is out-of-date.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.
How can I fix my printer printing ASCII characters?
1. Run the Printer troubleshooter
- Hit the Windows key and click on Settings.
- Select System on the left pane, then click Troubleshoot on the right.
- Click on Other troubleshooters.
- Find the Print troubleshooter and click the Run button next to it.
2. Update your printer software
- Navigate to your browser and go to the Software and Driver Downloads page for HP printers.
- Click on Printers, enter the required model number, and press the Submit button.
- Expand the Firmware category on the printer’s software page.
- Click Download to save the firmware listed there to a folder.
- Open the folder that includes the downloaded firmware. Then open the firmware file and follow the on-screen instructions to install the latest firmware.
3. Update the Printer drivers
- Hit the Windows key, type Device Manager in the search bar, and click Open.
- Navigate to Print queues, locate your printer, right-click on it, and select Update driver.
- Select Search automatically for updated drivers.
- Windows will find the most suitable driver and recommend you install it.
4. Run your printer’s maintenance tool
- Download the HP Print and Scan Doctor application.
- Open HPPSdr.exe from the download location. You might need to be an administrator to be able to do this.
- Click on Start and select your printer. If your printer is not present, reboot your printer, then choose Retry.
- Follow the prompts the application gives you and choose Yes if it asks to turn on printer updates. Then set your default printer.
- Now, select the printer that the Problem with printhead error arises for, and click the Next button.

Most printers have their own maintenance and troubleshooting tool but if it doesn’t, move on to the next solution.
