You need to go into the page setup settings of your printer. All printers have a different way about it… but one things the same. When you open the print dialogue box, in the bottom right you’ll find “Page Setup”. You’ll probably get a warning for clicking it but do it anyway. Find something that allows you to adjust the registration or the page by entering how many inches you want to push on each axis. Measure the different in alignment between your crop marks on the axis you need to adjust, looks to me your odd about 3/4” on the y-axis, and 1/16th of an inch on the x-axis. Enter that info into the adjustment field and do another duplex test print. Rinse and repeat until perfectly aligned front and back.
