Reports are designed to fit specific page sizes for optimal presentation. However, the client printer fails to maintain the designated page size, resulting in cropped/misaligned or distorted content.
Are you printing from a PDF or directly to the printer?
One area to check could be the “Printing Preferences” of the printer itself. Below is a snip from one of our label printers… you can set the label size here… as well as “unprintable area” which (I think) acts a default margins. So, if you values in there, it could be skewing/misaligning your print out.
