Welcome to the HP Community --
A couple of points - Most important first...
Note that if I don't explain this properly, that's on me.
There is more than one thing going on -- what follows is an honest attempt to sort the bits.
1) The paper size 3.5 X 5 inches is not listed as supported in the Specifications.
Smallest Custom paper size = 3.85 X 5 inches
AND
Standard Supported paper sizes / types in EWS include 4x5 and 4x6 - the significance of this is illustrated in point #2.
Short answer: Get some 4x6 inch Index cards.

and
2) The printer must be aware of the paper size loaded in the printer.
Reminder:
Small paper in supported size > only paper type Photo is supported in the photo paper tray.
and
This is not related to creating a Custom Paper Size form -- such is supported. The issue, if there is one, is making the printer aware of supported (as standard or custom) paper sizes.
Next,
"Aware" means you must be able to select the paper size / type on the printer control panel right after changing the paper (or when you open / close the tray). For sizes not listed, look for -- and if available, select "Custom" size.
Yeah, but we know about EWS!
Normally you could use the Embedded Web Server (EWS) to view / adjust Tray and Paper Settings for paper sizes / types.
In this case, EWS is less effective or useful -- The EWS for this printer lacks the "Custom" size option.
Samples - FYI only
EWS – Tray and Paper Management
Original EWS
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 and EWS version Dependent: Advanced section
Click Apply to save changes
Tray and Paper – Paper Size / Paper Type / Paper Weight
Paper Size, Type, and Weight loaded in the printer tray must be supported for use in that tray.
EWS (Embedded Web Server) provides access and control for Settings, including Tray and Paper.
Reminder
HP Smart Mobile might require that paper size / type is rechecked / adjusted before the content is opened for print.
Notes
Depending on the printer model, the Printer Control Panel touchscreen might provide access to Paper Size / Type settings immediately after the paper is (re)loaded into the appropriate printer intake tray.
New printer? Touchscreen Printer Control Panel locked against making changes? Try username "admin" and the PIN located on the sticker on the inside of the front door of the printer.
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 your paper is a custom size, look for "Custom" in the full list of paper sizes.
Remember >> Printers with more than one tray might only support custom paper sizes and types in one tray.
If EWS does not allow setting the paper size or size “Custom”,
If the printer includes a touchscreen display printer control panel,
Look for the setting for “Custom” in the Printer Control Panel after (re)loading the paper to be used
NOTE: Size Custom is 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, perhaps in limited sizes.
OR
If the "Custom Paper Tray" is Tray 2, then Tray 1 might only support Plain paper / limited sizes.
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.
