Questions before you print
Does this change my shipment or locker booking?
No. It only changes the page layout of your local PDF.
Why can software decode the PDF but not the printed label?
Physical output adds printer heat, head condition, media, contrast and wrinkles that software cannot measure.
Is this tool affiliated with InPost?
No. LabelCheckup is an independent PDF utility.
