Editable Font Selection Strings (5219)
The AX-3 Cobra+ fully supports the system command for selecting
fonts, and this section gives an introduction to fonts and font
selections.
This feature is applicable only in 3812/5219 emulation mode.
Font Identification
Number
The system specifies which font the IBM 3812/5219 printer should
use by the Font Global Identifier (FGID).
The FGID specifies:
• Fixed pitch value (CPI value) / Proportionally Spaced Characters
• Typeface (character style)
A PC type printer cannot recognize the FGID. It has to be translated
into a Font Selection String, which is an ASCII string.
The Font Selection
String
The translation to recognizable font information is controlled by 50
string parameters (Parameters #150 - #199).
Each string parameter contains:
• FGID (two hexadecimal bytes)
• Character Spacing (one hexadecimal byte)
• ASCII Character Set (one hexadecimal byte)
• Font Selection Sequence (any number of hexadecimal bytes)
Example (HP LaserJet):
Bytes 1 - 2 are the FGID number.
‘$0055’ is the FGID for the IBM 3812/5219 font Courier12.
