I am struggling to print out 1 inches square grid on A4-paper. The squares comes out about 1,8 inches.
I have tried on 2 different printers (Brothers DCP-L5500DN Laser printer, and a Epson ET-2820 inkjet). I also tried printing out different grids from Internet, and simple squares with Google Draw document.
When I print I made sure to set size to actual size, no paper margins, and used 300 PPI.
