• (2) Click on your Start button

• (3) Open Devices and Printers

• (4) Right click on your Deskjet 

• (5) Left click on Printing Preferences 

• (6) Click on the Paper/Quality tab

• (7) Select Advanced on the bottom right

• (8) Under the Paper Size drop-down select Legal 

• (9) Click OK

Now that the driver has been set to Legal, test printing. 🙂
