Selecting Fonts; Printer And Screen Fonts - Epson EPL-N2700 Reference Manual

Selecting fonts

Whenever possible select fonts from the font list in your software
application. See your software documentation for instructions.
If you are sending unformatted text to the printer directly from
DOS or if you are using a simple software package that does not
include font selection, you can select fonts with SelecType when
in the LJ4, ESCP2, FX, or I239X menu.

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 in your
computer, are used to display text on screen to represent the fonts
that will be printed.
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.
