My hp officejet 8600 plus will not print envelopes I am using #10 size envelopes, this is the size the box says they are and I remeasures them and they are the correct size. When I try to print on these envelopes I select the #10 size in Microsoft Word. Every time I try to print the Printer tells me that there is a paper mismatch and will not print on the envelopes? I have tried to adjust settings in Microsoft and loading the envelopes in different places but keep getting the same error message. Any help would be great

The following link is a downloadable Firmware flashing utility that will update the firmware in your printer:
Please note that your printer needs to be physically conencted to the computer to flash the firmware, either a direct USB connection or an ethernet connection. Your printer does not need to be installed with the above connection types, just simply hooked up in that fashion.
If that doesn't work, trying printing envelopes from a different text editing program to determine whether it's an issue with Word or not.
If it's happening from multiple programs then I would suggest a complete unistall of all HP Printer software from your computer and then try to reinstall.

Thank you for that info. Interestingly enough, I think it's a bug on Stamps.com because when I have had this issue of not printing on #10 envelopes (still do) it was only on Stamps.com. The printer does an excellent job printing from word.

Hi, I just purchased the 8600 Premium. Its installed and prints fine...but. Even though it recognizes that I have two trays, I cannot seem to get it to print from them both. I have gone into preferences in the printer software and changed the top tray to envelopes #10. However every single time I do this, it also changes the bottom tray to the same thing, abandoning the setting for letter size paper. Now when I go to the bottom tray and enter letter size paper, it changes it AND the top tray from envelopes to letter size paper ! Its like all or nothing !!!
Now I have changed the settings in word 2010 to reflect where the enelopes are and the fact that the printer pulls from the center...and envelopes now print just fine. However I can no longer print letters! It wants to pull from the top tray all the time and it says 'paper mismatch' error every single time i try. I am NOT trying to print envelopes and letters at the same time.
I do not know what to try now at this point. Thanks !

With all due respect to the folks who post our here, it would be good to be able to find a post that is a solution. All that seems to be presented is the problem. Too many people are experiencing the same problem when trying to print a #10 envelope from MS Word on their 8600 all-in-one HP printer. Clearly, there is either a serious bug, or is this is simply not well documented. Where is the fix for this problem. I bought this printer so I could print envelopes and can guarantee I have spent more in time than the cost of the printer, and still can't print an envelope. The time invested hasn't yet exceeded the cost of ink for the printer, but we are getting close on that front as well.
My error message continues to be a paper size mismatch?? **bleep**? I have loaded the size 10 envelopes as instructed into the paper tray, and when the print options are selected, I am telling Word that I want to print a #10 envelope. Nothing works. Initially, was getting an error message that said a section of what I was wanting to print fell outside the print boundaries...seem to be past that now but why the paper size mismatch? How many knobs are there to turn to set the paper size, and where are they?
