Welcome to the HP English Community --

There is generally only one fix for paper size / type mis-match.

Both the printer and the job configuration must be set to a compatible paper size / type.

The Paper Size / Type settings are available on the printer control panel right after the paper is changed or the paper tray is opened and then closed.

Alternatively, if the printer is on the network, use the Embedded Web Server (EWS) to view / adjust Paper Size / Type - Tray and Paper.

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

OR

Example - (Alternate EWS format - select new OfficeJet Pro printers and at least a few LaserJet printers)

Open your Browser > Type / enter the Printer IP address into URL / Address bar

Section Paper > Trays > click on Tray to configure

And (in addition and as available)

Section Print > Default Print Options > Select default tray

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.

Examples...

Certain paper sizes and types are reserved for the Photo Tray -

One Type > Photo Paper

Sizes (not at the same time) = 4x6 in, 4x5 in, 5x7in , 10x15cm

Tray 1 can handle a variety of paper sizes and types.

Example - EWS - Tray and Paper

Next,

As best can be done, the job configuration must reflect what the printer detects / has been set.

This means you cannot tell the printer it is set to Letter paper and then choose a different paper in your job setup.

and / or

If you have selected "Plain paper" in the printer EWS, you cannot select Photo Paper in the job configuration setup.

Sometimes the source of the mis-match is having not set the Source (Tray).

If -- in your job setup -- the Tray is set to Auto and that setting does not work as expected, select the Source / Tray.

Where you set the Paper Size and Type in the job depends on the application / software you are using.

The application / software that is available depends on your device (computer, tablet, phone) and the Operating System / version running on that device.

Example - HP Smart - Windows - Simple Photo Print - Select Photo Size on Letter Paper

HP_Smart_Win_Simple_Photo_Print_Letter_4x6_2

Example - HP Smart - Mobile - Photo Print
