Microsoft Windows 10 in S Mode

I try to print and I keep getting the PAPER SIZE MISMATCH.  I have tried several things but nothing changes.  I use the 8.5 x 11 inch paper.  I have changed all settings to LETTER and it still will not print.  I have the HP Office Jet Pro 6978.  I bought June 23, 2021.

Welcome to the HP User Community.

 

Windows S mode is particularly limited in what is allowed.

For example, applications can only be installed from the Microsoft Store

What?

This means you cannot install the Full Feature Software / full driver printer software in Windows S mode.

You can install and use the HP Smart application.

 

 

HP Smart (Windows) and the Embedded Web Server (EWS) can be used to check / modify the Paper Size and Type settings.

EWS can be reached from your browser and / or from within the HP Smart application.

What else?

A printer that includes a printer display panel (like your printer) provides access to the paper size / type setup.

 

Examples and how-to

 

Check / Adjust / Retain the Paper at the Printer Display Panel

 

Open Printer Tray,

If you have not yet done so, Remove / add desired paper size - type

else

Wait a few seconds

Close Tray

IF applicable for your printer:

On the Printer Control Display Panel,

Click Modify / Change / No-Yes (wording varies), adjust the paper size and type, Click OK

 

No Size?  If the size of the Paper Size is not in the Drop-down list, Select Custom

Note:  Not all printers allow selection of “Custom”
