We have modified our QC labels to contain more information and changed from a 4" x 4" label to a 4" x 6 1/2" label changing the orientation from Portrait to Landscape. Printing on the label begins approximately 2" from the left edge of the label not the x-position of 0.080" from the left edge of the label. On the Zebra GX420d Printer Preferences "Options" the Paper Format has been set to inch and landscape. The Size is set to Width 4.00" and Height 6.50". Please see the attachment to better visualize the problem.
