Wow, this is very good and helpful. Thanks for this! I use the PDF on a tablet.

This is actually very helpful, thank you. I don't need graph paper often, but my kids are old enough now that school assignments require it, and having to go to walmart for a book of graph paper is annoying.

I tried printing Gray, Dark, and Black on an HP LaserJet, but the colors were very faint in all cases. It was hard to see the grid.
