Loading fonts
DocuPrint NPS/IPS accepts downloaded legal Type 0, 1 or 3
fonts through the standard means used on other PostScript
devices for downloading fonts. Type 0, Type 1, or Type 3 fonts
may be loaded permanently on the system by the system
administrator using the font installation utility. This method
ensures that the desired fonts are available on the system and
saves time later by avoiding the repeated transfer of fonts
through the network.
NOTE: Only Type 0 OCF fonts are supported. Type 0 CID fonts
are not supported.
CAUTION
Downloading fonts with a PostScript file is discouraged because
printer performance may be degraded significantly. Instead,
install the desired fonts on the controller, then reference them
from within the PostScript file.
User-defined fonts
User-defined fonts can contain bitmaps or define the shape of
characters through PostScript operators (
lineto
,
curveto
,
fill
).
User-defined bitmap fonts are not portable across different
output devices. You may notice a marked difference in the quality
of rendering for bitmap fonts as printed on different laser printers.
The differences are attributable to device-dependent features
such as resolution, shape of device pixels, and other
characteristics. For further information on these characteristics,
refer to “Scan conversion details” in this chapter.
Type 1 fonts
Type 1 fonts are base fonts with character shapes defined by
using specially encoded PostScript procedures. Because
characters are drawn by PostScript procedures, many visual
elements that are not associated with fonts can be represented
as characters in a Type 1 font.
The multiple master font format is an extension of the Adobe
Type 1 font format and is supported by DocuPrint NPS/IPS.
