Assigning and Selecting Font Files
Each font file stored in printer ROM includes data for one of the three
standard character sets: ASCII, DEC Supplemental, and DEC Technical.
Each font file also includes data for one font, which is part of a type family.
You can identify font files by type family ID, font ID, and font file ID. (Refer
to Appendix E.)
The type family ID consists of seven characters. The type family IDs for the
standard type families used with ROM–resident font files are listed below.

The font ID has 16 characters (no lowercase letters permitted) and describes
the seven basic font attributes (including type family) of the ROM–resident
fonts. Appendix E lists the standard type family, font, and font file IDs for
the ROM–resident files.
To make a font file available for printing, you must assign a Select Graphic
Rendition (SGR) number (page 7–93) to the file. Then you can select the
SGR number for printing (page 7–95).
Default Fonts
When you power up or reset the printer, it selects SGR number 10 for
printing and data processing, and SGR number 19 for plotting and LG Near
Letter Quality, unless you have selected and saved another default.
