Printer And Screen Fonts - Epson EPL-N2000 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 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.
