@isaac_1753 I would also check to see if your printer paper tray size has A4 paper in it. For example, I am in Canada, and the paper size for us is letter size at 8.5" x 11" (portrait mode) while an A4 size is 8.27" by 11.69" — if anyone sends this to an office printer, or personal printer, and sent the A4 to the printer, it won't print, bcause the printer doesn't have the correct paper. Secondly, verify your document's resolution is appropriate for print (e.g., 300 PPI). And make sure "Scale to Fit Media" is unchecked, and the print scale is 100%. Select "A4" as the paper size. Also, disable any "fit to page" scaling. Load actual A4 paper into your printer. Hopefully, you should be able to get your A4 Photoshop file to print at its exact intended size.
