That is not what I am asking. The ink comes out of its cartridge via an aperture opening. The size of the aperture is going to be either designed in inches or millimeters. Which? The dot that is formed on the paper from the ink mist will also be in inches or millimeters.

I remember the old ink plotters that had pen widths in millimeters. One size was 0.35 mm. Even mechanical pencils have their lead sized in rounded metric. Always was that way. With laser and ink jet printers common, one would think the dot size would be naturally be in millimeters. Isn't it?

The way to metricate dot size in printers is to set it to a multiple or submultiple of 25 µm, which is used in plotters. PostScript doesn't care; you can set the font size to 2.718281828 points and scale the image by 1.618034/0.70710678. Pierre ________________________________ Windows Live Hotmail just got better.
