Downloading Soft Fonts
The process of transferring soft fonts from a host computer to the
printer’s user memory (RAM) is called downloading. Designate a
unique identification (ID) number prior to the download of a font. This
number is then associated with the soft font. This number is assigned
using the Font ID command, described later in this chapter.
Subsequent manipulation of the soft font is accomplished using the
font’s ID number. If a font is already associated with this ID number in
the printer, the existing font is deleted during the download.
Several commands are required to define a font before downloading it
to the printer. These commands are described in detail in Chapter 11.
Hewlett-Packard font files include the necessary commands that
define the symbols of a font. Assigning a font ID number and then
copying the font file to the printer downloads the font. Scalable fonts
and typefaces may be prepared by font management software such
as HP’s Type Director. Once prepared, scalable fonts are downloaded
in much the same manner as bitmap fonts.
Once downloaded, a soft font occupies a portion of user memory
(RAM). The number of soft fonts that can be stored in user memory is
limited only by the amount of available user memory.
