My HP OfficePro Jet 8720 Printer allows me to adjust the paper tray for envelopes, in this case 6 3/4 size, but won't print them saying the printer only supports 3 different sizes of paper; letter, legal and A4.

Edits - Add example for 6x9 inch envelope - Windows, using Word
If you have the optional tray 2, this tray only supports plain paper.
If you are loading envelopes into the main tray, you need to tell the printer control panel about the paper type / size.
Check / Adjust / Retain the Paper at the Printer Panel
Open Printer Tray,
If you have not yet done so, add desired paper type
Close Tray
IF applicable for your printer:
On the printer control panel, Click Modify (wording varies), set the paper size and type, Click OK
NOTE: If the size of the Paper Size is not in the Drop-down list, Select Custom
Set the Preferences - Windows
- The following assumes the Full Feature Software has been installed.
- Check / enable the printer as the “Default Printer”
- Select and adjust settings in each category for the Media (kind of paper), source (tray), and paper size.
Control Panel > icon view > Devices and Printers > Right-Click on your printer > Set as Default
Control Panel > icon view > Devices and Printers > Right-Click on your printer > Printing Preferences >
Tab Printing Shortcuts > Click / Highlight preferred shortcut > Click Apply > Click OK to exit
If the printer software supports the feature, change the settings as desired, then use “Save as” to create a Custom Shortcut.
OR
Windows key + S (search for) Printers and Scanners
Left-Click on (your) Printer > Manage >
Printing Preferences
Select a shortcut and / or set “preferred settings” for paper, source (tray), other settings
Optional (if / as supported on the printer): Save As > enter a name for your custom shortcut
Click OK to save the preferences
=============================================================
If the size of the envelope you are printing is not in the standard size list for supported envelopes, you must create a Custom Paper Size form for your envelope.
Allowed custom size range noted in the Specifications

76 to 216 mm (3.0 to 8.5 inches) wide and 127 to 356 mm (5.0 to 14.0 inches) long | ☑️
