AutoShipFlow online tools can adjust PDF pages, crop blank space, resize labels, merge files, and generate printable PDFs. They cannot read or change the actual paper loaded in your printer.
If the processed PDF preview looks correct but the physical print is shifted, scaled incorrectly, or cut off, check your printer paper size, scale, margins, calibration, and driver settings.
