Can't get QR code to print centered

Hi everyone!

Having a really hard time trying to get QR Codes to print centered from Preview. I also tried printing from the web browser and Photoshop. So far, Preview gets closer than the rest. I'm just wondering if I have some silly setting. I that is wrong. I have attached a photo of the best version I have printed so far. I need to print 10-20 a day so I'm sort of panicking at this point. I would greatly appreciate any help at all resolving this! The printer is a Zebra ZM600 and I am printing from an iMac 18,3 (10.13.4). Thank you!
