Add OFFSET printing to MS Access form for precise label printing

I have a bespoke (built 4 years ago by a freelancer.com expert) MS Access application. Amongst other things it creates labels (2 x 6 on an A4 sheet) for me to print out. The PROBLEM: my printer and the application are not in line with the printing margins so that the printing runs over the edge of the labels. The SOLUTION: I currently use a PDF editor to make offset adjustments but this is time-consuming. Better to add an OFFSET printing option to the application.
