When printing from an application, make sure the selected printer is the correct printer you want to use to print your job.
It is useful to have the default printer set to be the printer you use most often for printing.
The font you are trying to print may not be available in the program font selection box. Not all fonts are designed to be printed; make sure the font is a TrueType font. See the program documentation for more information.
Most programs do not print a stretched or resized font.
