Printer And Screen Fonts - Epson EPL-N2010 Reference Manual

Read this section if you would like to know more about fonts and see samples
of the installed fonts.
To select a font, use your application program.
Font problems are uncommon but some may occur, such as:
The printer substitutes a font other than the one you selected
with your software.
The printed page does not exactly match what is on screen.
These kinds of problems usually occur if you use an emulation other than
LJ4 or when you are trying to print fonts that are not installed in the printer.
If you have font problems, read "Printer and Screen Fonts," below, to find
out how to fix them.

Printer and Screen Fonts

Fonts are installed on both the printer and the computer. The printer fonts,
which reside in printer memory, are used by the printer to print text. Screen
fonts, which are stored on your computer's media, are used to display text
on screen to represent the fonts that will print.
Two separate sets of fonts are needed because the monitor and printer have
different requirements for producing fonts. The monitor normally uses
bitmap fonts that are specially designed for the screen's resolution. A bitmap
is a dot-by-dot representation of an image or character. The printer, however,
uses an outline font that is created from a mathematical formula that
describes the outline of each character. Using outline fonts allows the printer
to render any character in the requested size.
Note:
The distinction between printer and screen fonts is not as important when you are
using TrueType fonts, which are included with Windows. TrueType is an outline
font format that can be used by both the printer and the screen.
