Function address ox5aaf6fda caused a protection fault appears everytime i try to print since installing windows 8.1

Try Using the HP Print Diagnostic Utility in Windows - HP Customer Care (United States - English)

Uninstall all HP software. Then using regedit, go in there and delete any and all HP registry files that appear then reinstall the software and cross fingers.

Try staples or home depot if they are still open otherwise you have to order it from HP or you could try the new egghead. HP's address is www.hp.com

Re-install the software for your printer. Download the drivers from the HP website and use the most current drivers for your product.

Also, check disk needs to be run on your unit to verify there are not other issues with your OS(Operating System).

Given the types of codes you have provided, it looks like you are running a Windows OS.
To run the check disk option, press and hold down the Windows Insignia key +S. This will bring up the Windows search option. Type "command prompt" and there should be a secondary window that shows you the results of your search. Look for the Command Prompt option and right-click the option and select "Run as Administrator" by highlighting the option and then left clicking your mouse.

A black window will come up with a variation of,"C:\Windows\System32\"; at this prompt you will see a blinking line\cursor. Type "chkdsk /r" then press enter. A report will come back stating that chkdsk cannot be run on "mounted" volume. Do you want chkdsk to run the next time the computer is restarted? Y\N
Press Y then enter.

Close the command prompt window and restart your PC. *WHEN IT RESTARTS, IT WILL TELL YOU TO SKIP CHECK DISK WITHIN X AMT OF SECONDS... DON'T TOUCH ANYTHING!!!*
Once it has completed, it will boot into Windows normally and if there are any issues, it will tell you during the scanning process.

Hope this helps.

If not, then bring up google.com and download and run this: Downloads AdwCleaner ToolsLib
This may also help.

Check two areas
1.. It could be the software your using to print the envelops.

2...It could be the printer driver.
Go on HP's site, and check and see if there has been any updated printer driver, or patch file. Hope this helps.

Hi,

Here's your solution. Good Luck!

You didn't say what type of printer connection you have (Parallel Port, USB, etc) and this may not help any but I do know that HP Printers are VERY finicky about not pluging in your USB cable until told to do so.

Also, did you uninstall the printer software prior to doing the reinstallation? That can sometimes make a huge difference also.

Probably the best and easiest solution for your problem would be to buy an EDIMAX USB-Ethernet print server, or something equivalent. I have several of these running on the network at work. They're easy to setup and they work great.
