Easy Post Label Size Adjustment For "Print Shipping Labels" Function

Hi Acumatica community,

Does anyone know how to adjust the file that is created when you click “print shipping labels” (from the easy post integration) so the size of the label works for a label printer? We use the zebra printers where the labels print directly to a sticker so we need to remove the extra white space on the page or have the page size adjusted to reflect the 4”x6” label size.

Our workaround is to print the labels one by one, but it seems unnecessarily time consuming.

Thanks for any advice or ideas!
