Hi TaylorLee,
Welcome to the HP Support Forums! :) I understand you are having problems printing A4 full size paper on your HP Deskjet Ink Advantage 2060. I notice where you are given the option to select Media Size it is listed as Defined by Driver, are you able to change it A4 paper size?
Also the only difference in the 2 I am seeing is the height it is off by 0.0042cm, can you change this to match the height settings of the Epson?
Please let me know which Operating system you are using, I will watch for your reply.
Thank you,
