Graph paper printing program
for Windows 95/98/NT/2000/ME/XP: excellent! Prints many different types of
graph paper. Graph Paper Printer is a program designed to
print out an amazing variety of graph papers, customized and impossible to find
in stationeries: lin, log, polar, axonometric, isometric, probability, square
root, quadratic, Rayleigh, Weibull, Smith, binomial, Mercator. A bonus is made
of music staff manuscripts, shapes, patterns, calendars, handwriting paper,
tables, lego paper, targets, dial indicators. You can add titles, captions,
copy/paste in your word processor. Printing is possible up to A3 format. Graph
Paper Printer is primarily an educational tool that is useful from the
elementary level to university, but will help at home for hobbies and in any job
related to sciences or designing. Definitely recommended. $20.
