A4 measures 210 × 297 mm. Letter measures 215.9 × 279.4 mm. Letter is slightly wider, while A4 is taller. A layout that fits one may not fit the other. Always choose the format you actually load and check the preview again after changing it.
Before you print
Use Actual size or 100% in the PDF print dialog. Match the paper format and disable any further resizing in the printer driver. The preview shows the PDF layout, not a guarantee of your printer’s printable area. Start with ordinary paper and measure before using photo paper.
The 20 mm scale check
The optional control square is 20 × 20 mm. It reserves space at the bottom of every sheet, so enabling it may add a page. Compare both measured sides with 20 mm. For example, a 19 mm side indicates 95% scaling. Do not enlarge the photo to conceal a scaling problem.
