If your HP printer is printing random characters, symbols, or garbled text instead of your intended document, it can be frustrating. This issue usually arises due to driver problems, incorrect printer settings, or corrupted print data.
What Causes HP Printer to Print Random Characters?
Before fixing the issue, it’s important to understand the common reasons why HP printers print random characters:
- Outdated or Corrupted Printer Drivers: Incompatible drivers may send incorrect commands to the printer, causing garbled output.
- Incorrect Printer Language Settings: Some HP printers support multiple page description languages (PCL, PostScript). Wrong settings can produce random symbols.
- Faulty USB or Network Connection: Poor connectivity between your printer and computer can corrupt print jobs.
- Corrupted Print Queue: Pending or stuck print jobs can send incomplete data, leading to random characters.
- Software Conflicts: Conflicts with applications, antivirus, or firewall settings may interfere with printing.
