I am using Adobe Acrobat on Windows 11 to print an A4 document as an A5 booklet on a Lexmark MS317dn laser printer.
With default printer settings in the Adobe Acrobat dialogue, the document is scaled down to about 97% of the 70.7% that I would expect for A4 to A5 conversion and left-justified. This makes the printed A5 pages off-centre to the left by about 4mm. Up until a few months ago, selecting the "Use full printable area" in the Properties -> Paper/finishing dialogue corrected this and produced an acceptable result. Doing this now, however, results in a properly scaled A5 document but it is overly left-justified so I get a negative left margin (approximately -3 mm) which means, of course, that the pages are still about 3mm to the left of centre.
This applies to any document.
