GridOMatic is a freeware program for creating and printing out your own graph paper. Lovely little utility, free for personal use (although the developer asks for contributions and contact for commercial purposes).
The only purpose of this little tool is to print graph paper, either as millimetric (with 10th divisions) or imperial (with 8th divisions). A laser or inkjet printer is capable of printing paper of a very high quality, and as a bonus you can adjust the scale, to enlarge/reduce the grid and suit your needs of any scale drawing.
Looks like it's windoze only. Try this – works on Macs also. http://www.incompetech.com/graphpaper/lite/
