Resolving Printer Issues: How to Fix Random PJL Print Language Printing

Introduction

Encountering random PJL print language output from your printer can be perplexing and disruptive to your printing tasks. PJL (Printer Job Language) is a language that provides a way for applications and printers to communicate. When PJL commands are printed as text rather than executing as intended, it indicates a technical issue that needs troubleshooting. This guide will walk you through steps to identify and resolve this problem effectively.

Understanding PJL and Its Role

PJL commands are typically embedded in print jobs to control various aspects of the printing process, such as paper trays, duplex printing, and job settings. However, when these commands are printed out as text instead of being processed by the printer, it suggests an interpretation error or miscommunication between the printer and the computer.

Steps to Fix Random PJL Print Language Printing

  1. Update Printer Drivers and Firmware

    Outdated printer drivers or firmware can cause PJL commands to print instead of being executed. Follow these steps to update:

    • Check Manufacturer’s Website: Visit the printer manufacturer's website and download the latest drivers and firmware for your printer model.
    • Install Updates: Install the downloaded drivers and firmware updates according to the manufacturer’s instructions.
  2. Check Print Settings and Document Properties

    Incorrect print settings or document properties can sometimes trigger PJL commands to print out. Here’s what to do:

    • Verify Print Settings: Ensure that the print settings, such as paper size, orientation, and print quality, are correctly configured in both the application and printer preferences.
    • Check Document Format: Ensure the document you are trying to print is in a supported format and doesn’t contain embedded PJL commands that might confuse the printer.
    • Check Printer Processor: Ensure that the print processor is set to winprint for most black and white default drivers. If your printer is printing out random PJL language it's best to start with the print processor setting. You can find this under printer preferences Advanced tab, then click on print processor and change to winprint. This should resolve the issue. 
  3. Clear Printer Spooler and Reset Printer

    Clearing the printer spooler and resetting the printer can often resolve PJL language printing issues caused by temporary glitches:

    • Clear Print Queue: Open the print queue on your computer, cancel all pending print jobs, and clear the print queue.
    • Restart Printer: Power off the printer, wait for a few minutes, and then power it back on. This action can clear any temporary issues and reset the printer’s internal memory.
  4. Check for Malware or Print Job Corruption

    Occasionally, malware or corrupted print jobs can inject PJL commands into print jobs. Here’s how to address this:

    • Scan for Malware: Use reputable antivirus software to scan your computer for malware that may be affecting print jobs.
    • Reprint Document: If possible, try printing a different document to see if the PJL language issue persists. This helps determine if the problem is with a specific document or a broader issue.
  5. Consult Manufacturer Support or IT Helpdesk

    If the issue persists after trying the above steps, contacting the printer manufacturer’s support team or your organization’s IT helpdesk may be necessary. They can provide specialized assistance and diagnose any hardware-related problems with the printer.

Conclusion

Resolving random PJL print language printing issues requires a systematic approach to identify and correct underlying causes. By following these troubleshooting steps, you can effectively restore your printer’s functionality and eliminate PJL print language errors. For further assistance or more complex issues, don’t hesitate to seek professional support from the printer manufacturer or IT experts.
