Some labels are not on an 8.5 x 11 sheet. When I try to change the paper size in page set up to my labels...the labels print to the left as opposed to the center based on the printer's feed tray. Any ideas how to solve this issue?

I am not sure am following you exactly. Two general notes for printing labels:

1. The FileMaker label templates are not perfect. They often require some setup of the layout print settings. Go to Layout Setup... > Printing tab to set the print area parameters.

2. If the print setup is changed, the script storing the print settings needs to be replaced with the new print setup.

Trying to print labels. The labels are on paper size 8.5 x 5.5. However when a custom paper size is defined and an attempts to print the labels they do not line up properly. Filemaker shifts the printed text.
