HP ENVY 7830 printing code-lines instead of file content

[AnnaEmma]

Hello

I've suddenly started having issue when trying to print files. Despite the status of the printer was marked as "ready" the files got stucked in the queue and an error message pop-up, impossible to print. Therefore I've downloaded the HP Print and Scan Doctor who suggested a couple of additional drivers. With those installed, the printer is now receing the print order, however it only prints non-sense code line (looks like programm language) instead of the file content. 

Any idea how to fix it?

Thank you

Hi @AnnaEmma

 I'd like to help!

I understand the printer prints unexpected texts.

To assist better-

1) Does the copy print out the same way? 

2) What's the application you are trying to print from? Have you tried printing from a different application or device? 

Try the below suggestions to resolve the issue-

Cancel the print job

Cancel the print job before performing a printer reset.

1. In Windows, search for and open Control Panel.

2. Under Hardware and Sound, click View devices and printers.

3. Double-click the printer icon, and then double-click See What's Printing.

   The print queue opens.

4. Click the print job you want to cancel, and then click Document.

5. Click Cancel, and then click Yes to confirm the selection.

   NOTE: 

   If the lights on the printer continue to blink after you cancel the print job, the computer is still sending the job to the printer. Either delete the job from the print queue or wait until the computer finishes sending information. The printer returns to its ready state.

Continue to the next step.

Reset the printer

Resetting the printer can often resolve printing issues.

1. With the printer turned on, disconnect the power cord from the printer.

2. Unplug the power cord from the power source.

3. Wait 60 seconds.

Print from another program

Print from a software application other than the one where the issue occurs to make sure the issue is not related to specific software.

1. Open any software application other than the software where the issue occurs. For example, if you used image viewing software when the issue occurred, try opening a word processing software application such as Microsoft Word.

2. Open a file in the new software, or create a new file for this step.

3. Print the file.

   • If the document in the alternate software prints successfully, do not continue troubleshooting. The software where the issue occurs might be the cause. Continue to print from different software, or contact the software manufacturer for help.

   • If the document in the alternate software also exhibits the unexpected text issue, continue to the next step.

     Print from another program

Uninstall the printer driver-

 Let's try and uninstall the printer software from the root level on your PC and install the full feature printer software.

--->In Windows, search for and open Programs and Features.

--->Select your HP printer.

--->Select Uninstall.

--->In Windows, search for and open Devices and Printers.

--->In the Devices and Printers window look for your HP Printer. If you see it listed, right-click on it and choose "Delete" or "Remove Device.”

--->Open up the run command with the "Windows Key + R" key combo.

--->Type printui.exe /s and click OK.

--->Click on the Drivers tab.

--->Look for HP Printer driver. If you see it click on it and click remove at the bottom.

--->Select OK.

--->Select Apply and OK on the Print Server Properties windows.

--->Close Devices and Printers.

And then reinstall the printer full-featured drivers from the software and drivers page 

Hope this helps! Keep me posted.
