It appears there’s an issue when printing directly from an iPad to a Brother 5900 printer, specifically concerning incorrect scaling of the printed document. This problem has been observed across different Brother laser printers and even an Epson printer when using AirPrint, suggesting it’s not isolated to a single printer model or brand.
The user initially encountered this while trying to print a document designed in Affinity Designer on an iPad Pro. Upon printing, the size was unexpectedly wrong. Interestingly, printing the same document from a Mac computer resulted in the correct output. This indicates the issue might be related to the iPad printing process, possibly in conjunction with the Brother printer.
Further investigation revealed a consistent workaround. By exporting the document from the iPad as a PDF file first, and then printing the PDF, the scaling issue is resolved, and the document prints at the correct size (100%). This suggests the problem lies in the direct printing process from the iPad, not with the document itself or the printer’s basic functionality.
While the exact cause remains unclear, this PDF export method provides a reliable solution for users facing incorrect print scaling when using an iPad with a Brother 5900 or similar printers. If you are experiencing this issue, exporting your document to PDF before printing is a recommended step to ensure accurate print sizes.
