Changing the paper size on an HP printer is a straightforward process:
Open the document you want to print and select the “File” menu in the upper left corner. From the dropdown menu, select “Print” to open the print settings.
Select your HP printer from the list of printers available.
Navigate to Properties or Preferences, which usually opens a new window with more detailed settings.
Select the “Paper/Quality” tab in the new window.
In the “Paper Options” section, you will see a drop-down menu for “Size is”. Select the desired paper size from the list of options.
Click “OK” to save your settings, then click “Print” to start the printing process.
Please note that these steps may vary slightly depending on the model of your HP printer and the operating system of your computer.
