How do I change paper size manually on HP 8600 printer?

[emzie8]

I am trying to print 4x6 pictures from my phone on photo paper and every time I load the paper and try to print it says there is a paper mismatch. How do I change the paper size physically on the printer? I see a lot on how to do this from a laptop, but I need to do it manually on the printer or through my phone and there doesn't seem to be an option for it.

Hi@emzie8,

Welcome to the HP Support Community! I'd like to help!

I see you are looking to change the paper size on the HP Officejet Pro 8600 Printer.

I have a few recommendations 

• In the Print window, click Preferences, Properties, or Printer Properties. Click the Paper/Quality tab, and then click Custom. Click New, type a name for the custom paper size, select the width and height, and then click OK to save the paper.
• Click Start, point to Settings, and the click Printers. Right-click the appropriate printer, and then click Properties. Click the Paper tab, and then click the paper size you want to use in the Paper Size box. Click OK, and then close the Printers folder.. 

Hope this helps! Keep me posted.
