The paper was close enough for the purposes of doing a sketch; but if I had wanted to do precise work or make a pattern that could be pasted on a piece of work for making parts, I would have been in deep dodo!! Since both programs returned the same result, I am assuming the problem lies with the scale in my printer rather than the software,itself.
Now for the good part. In the program that Alfred linked to, there is some flexibility and this type of difficulty can be corrected. Since I was getting 5.5 rows for the desired 5, I set up a little ratio and calculated that I needed to ask for 4.545 rows per inch. Plugged that figure into the program and got a perfect 5 rows per inch or at least as close to it as I could measure with my machinists scale!!
Maybe others have printers that print closer to true scale or maybe no one has checked to see if their graph paper really is accurate?? Regardless, there is an easy way to adjust for scale problems if you should run into same!!
Alfred: Thanks again for that link.
