Can't switch from 4x6 to letter

[AwkaMonster]

I have the all in one remote and the hp plugin service. I printed some photos the other day, now I'm trying to print on letter paper. However, it won't let me switch the paper size. When I go to printer settings and press tray & paper settings, it doesn't load. It says there's a security risk. Also, when I want to print something it doesn't give me any other option then 4x6.

Hey there! @AwkaMonster, Welcome to HP forums.

I understand that you are unable to change print settings on your printer.

Please try few steps recommended below.

In the program, you want to print from, click File, and then click Print.
Make sure your printer is in the Name or Printers drop-down list box, and then click Properties, Printer Properties or Preferences.
Click the Paper/Quality tab.
Click Advanced, if necessary, and then click Paper Size.
Select the paper size that matches the size and type of paper loaded in the printer tray, and then click OK. If there are no matching paper sizes, select the size from the list that is closest to the size of the paper loaded in the tray.
Click OK, and then try to print.

If you are printing envelopes, you might need to change the mail settings of the program you are printing from in addition to adjusting print settings in the driver. For information on changing envelope settings in Microsoft Word, see How do I adjust the envelope settings in Microsoft Word? in the FAQ section of this document.

Refer this article to further troubleshoot paper mismatch error.

Also, refer this article to know creating custom size paper.

I'll watch your reply.

Have a beautiful day ahead! 🙂

I figured it out. I had to move the guide all the way to the left and then back to where the paper was. Not sure if that was exactly what I had to do, but it worked.
Have a good day!
