Using the PostScript page description language, I was able to create original graph paper designs.  For more information on PostScript, click here to visit an Adobe (the creators of PostScript) partner website.  Below are some graph samples converted to PDF (Portable Document Format) files which will require the Adobe Acrobat Reader or Exchange, however, in the original PostScript files, with a few parameter changes -- the whole grid size for the graph can be changed as well as the assumptions about the page size.  

Some possible graph sizes produce results which cannot be cut and tiled to manually make larger pasted-together sheets of graph paper.  The only real advantage of store-bought graph paper is the commercial printing process can use a particular shade of blue which does not photocopy -- the final work is seen but not the grid lines.  The advantages of unique, custom, printed when needed, helpful graph papers should be self-evident.
