Scale Converter

I would like to add a word of caution about the printable scale idea.

 

Some printers do not print to scale. I had an expensive HP office laser printer that would print a 10.0 inch line from a CAD program as something like 9.94 inches with a 1.0 printing scale in the HP driver. To get it to print the correct length I had to adjust the printing scale to 1.064, and that still wasn't exactly the correct length.

 

It may not sound like much, but 0.06 inch (1.52 mm) is a significant error, and multiple errors can add up to a significant problem.

 

Before you print anything on any printer/plotter where you need a precise dimensions, be sure to test the printer/plotter to see if it actually prints to scale!

My plan is to print a reference line next to the scale line.
