I am using a PC with Windows 10 connected to a Brother HL L2320D Printer. At the beginning I simply used the default printer driver in Windows (as I did not download and install any driver from the Brother printer website), however, I found the printer did not print A4 documents in the correct size, the documents tended to automatically shrink by around 5%, leaving an unexpected margin on the left and bottom.
Then I tried to download the printer driver from Brother website, installed it and replaced the original driver. The problem was rectified when the documents were printed on paper.
But then when I tried to generate a PDF file from an A4 sized Word document (I am using Word 365) using a free PDF driver, the resulting PDF was in the wrong size -- the PDF size became 21.59 x 27.94cm (which is the size of Letter instead), and worse still, the contents were shrinked once again by around 5%. If the page had a colored background, a 1cm margin was clearly seen on both the left and right sides.
I checked the Printer Property settings from the and Word Print settings, both were set as A4 already. The stranger part was, I tried different PDF printer driver software, such as Microsoft Print to PDF (which was available in Windows 10), FlexiPDF, PDF Creator, all of them had the same problem, the only exception was PDF Architect 8, which could generate the correct A4-sized PDFs without shrinking the content.
Thinking it might be these PDF drivers were affected by the default printer driver as I installed them before correcting the problem I mentioned in the first paragraph, I uninstalled the PDF driver software and re-installed them again, but the same problem still exists. What can I do to correct this problem?
