Why are labels from Canon MB5400 printer only partially printing?

[SG12]

It seems all of a sudden I am unable to print labels correctly, direct from Shopify. If I print direct from Shopify, label is so big it only prints a portion of the entire label on the paper label. This occurrs with both USPS and UPS labels.

I have two printers: 1. Canon MB5400. 2. EPSON WF-3640

Same issue on both printers.

If I download the label from Shopify and print, it prints out just fine, both printers, both USPS and UPS.

Also tried test print through settings/shopifyshipping/print test label, still same issue.

Would have liked to provide screen captures, but this app does not like .pdf or .png files.

Any help would be appreciated...
