I was trying to figure out how to print a series of lines at a set measurement.
ex. 20 lines at 4.0123 inches. Anyone with some information that would help get me started would be greatly appreciated.
This would depend on the size of your screen which I'm fairly sure is impossible to reliably determine.
If you want to take a ruler to your particular monitor, you can write 20 lines and then modify the windows registry (windows only) to adjust the size of the font until you get the size you want.
Do this by typing "regedit" and going Computer>HKEY_CURRENT_USER>Console and play with FontSize.
