PSM font is the same width as the W in every other PSM font. Therefore, it is possible to have
only one character-width table that applies to every PSM font.
Posture
Refers to a character's incline, or tilt. Roman posture is upright. Italic posture is inclined to the right.
Type Size
Also called point size. Specifies the overall height of the font, measured in printer's points. A point is
1/72 inch. For example, a 12-point font is 1/6 inch high.
Typeface
Also called type style. Specifies the shape and design of each letter of the alphabet. A complete
alphabet of letter designs makes up one typeface.
Weight
Refers to the thickness of the strokes that make up the characters of a font, as in a bold font weight.
Font and Code Page Selection
Printers with an IPDS feature receive IPDS commands to specify fonts. The IPDS command set can select
any font or code page supported by the printer. See the printer User's Guide for a list of the IPDS fonts
supported. However, host software may restrict the actual fonts or code pages that can be selected. This
includes typographic and nontypographic fonts in all pitches, point sizes, and widths. The information
provided to the printer to select a font is called a GRID (Global Resource Identifier). The GRID consists
of the following (See page 93 "Font Terms" for a description of these terms):
•
FGID (Font Global Identifier)
• GCSGID (Graphic Character Set Global Identifier)
• CPGID (Code Page Global Identifier)
• Font Width
For typographic fonts with the same FGID, specify the FONT WIDTH parameter to the printer. The
printer needs the font width parameter to identify the font in order to specify the point size. The FONT
WIDTH parameter is described in detail in the IPDS section.
You can select the code page and code page version from a configuration setting. Refer to your printer's
User's Guide for instructions on changing code page and code page version configuration settings.
Some system software does not allow you to change code pages by software and uses the printer
default code page for printing. The printer factory default character set is 0697 and the code page is
00037 version 1.
This may require you to change the printer code page to match the system software.
• When using an application that does not allow selection of font width, use the alternate FGID when
available to access typographic fonts.
