I'm using this website to try and print a grid of squares on A4, but it doesn't seem to matter what I do, the grid will not print the full length of the sheet. https://incompetech.com/graphpaper/plain/ I set the border margins to zero on the website's set-up procedure (for some reason I can't choose borderless printing on the print set-up because it then assumes I'm printing photos and prints at a snail's pace). The grid prints to full width okay, but stops at about 1.5cm from printing to full length. Anyone know what I'm doing wrong, or need to do to compensate. There's a custom page size available, and I tried setting this to about 5cm longer than the standard A4, but got the same result.
