My HP Deskjet D1420 Prints everything a half inch to the right. How can I fix it? -

I m printing to pages on one side so that I have two portrait pages on landscape. But the problem is that the two pages aren t seperated equally. The middle comes out a half to a full inch farther right than it should. Can I adjust it?

settings

you can see if you can change the margins in the settings or if you print a normal page and it comes out 1/2 an inch to the right and you do the above you printer may be broken

step1: buy a new one step 2: ??? step 3: Profit
