Welcome to the HP Community --
This might be faster if we knew where you are seeing the Drop-Down menu.
What else?
- The Operating System / version is important because different devices (computers, tablets, phones) run different Operating Systems.
- The Operating System impacts which applications and software are available.
- The applications and software dictate which settings are available.
OK - Moving on.
Using what we have:
HP ENVY 6458e All-in-One Printer
A9 envelope measures 5-3/4 × 8-3/4 inches (146 × 222 millimeters)

Printer - Tray and Paper
EWS > HP Document / How-to
Use the HP printer Embedded Web Server (EWS)
NOTE: Find printer IP address
Section How do I manually assign an IP address to my printer? Items 1-2
EWS – Browser – Tray and Paper Management
Open your Browser > Type / enter the Printer IP address into URL / Address bar
Tab Settings > Preferences > Tray and Paper (Management)
Select / Adjust settings for Paper Size / Type
Model Dependent: Advanced section
Click Apply to save changes
Tray and Paper – Paper Size / Paper Type / Paper Weight
Reminder
HP Smart Mobile might require that paper size / type is rechecked / adjusted before the content is opened for print.
Paper Size, Type, and Weight loaded in the printer tray must be supported for use in that tray.
EWS provides access and control to check / adjust Tray and Paper Settings.
Notes
Depending on the printer model, the Printer Control Panel might provide access to Paper Size / Type settings immediately after the paper is (re)loaded into the appropriate printer intake tray.
Trays
- If the printer lacks a second tray, all paper / types are supported in the single available tray.
- Printers that include a Photo Tray generally restrict the paper sizes and paper type supported in that tray.
Custom size?
If EWS does not allow setting the paper size or size “Custom”,
If the printer includes a touch display printer control panel,
Look for the setting for “Custom” in the Printer Control Panel after (re)loading the paper to be used
NOTE: Not available for all printers
What?
Paper Size, Type, and Weight must be appropriate for the tray in which that paper is to be used.
Depending on the printer model, Tray 1 might be used for Custom media.
In this scenario, Tray 2 might only support Plain paper.
OR
If the "Custom Paper Tray" is Tray 2, then Tray 1 might only support Plain paper.
Printers that include a Photo Tray generally limit the size and type of paper that the Photo Tray supports. Example: Depending on the printer model, the Photo Tray might support only 4x6 inch photo paper.
