Somewhere in all the stuff I have read about Excel, I seem to remember that
it is not a precision measurement system. It is a number crunching
spreadsheet with some additional capabilities and features, one of which is
not CAD/CAM. For precision printing you will require special software with
matching hardware. The printer itself must be calibrated to the CPU
interface. Even if you had been lucky enough to get a precise measurement
using they standard Excel software and local printer, the very first time you
try to use it anywhere else would be a failure.

Hi,

If I create a rectangle shape with a width of 10 * 72 / 25.4 and then print
it and measure the width with digital calipers, the actual width is 10.27 mm
not 10 mm.

Can anyone tell me why please and how to print a rectangle of 10 mm width?

I actually want to get the precision down to under 1/2 mm.

TIA
Lisa
