I use 'point size', instead of 'pixel size', when defining my fonts in Citect. The text displayed using these fonts is exactly the size I want, but the same fonts print very small size text when used with Plot functions. Why?  

Citect converts point size to pixel size just before creating a new font. When doing this conversion Citect reads the device capabilities of the display driver it is using to find out dots-per-inch (dpi). Typically, dpi for display drivers is between 70 to 100. If the same font is used with a printer whose dpi is 300 the text printed will be very small. The users should configure a different set of bigger fonts in Citect to use solely with the Plot functions. The point size of these fonts depends on the resolution of the printer in use, but as an example, the point size of a font to be used with a printer with 300 dpi should be about 4 times the size of the font used with VGA resolution display driver, ie. 300 / 72.
