The vertical point size is the real common ground. So to get a 12 point size, a fixed width font will use a
font width of 144; 10 cpi. A typographic font will use a font width of 80. To keep compatible sizes this is
also translated from 10 cpi. The FGID defines which range to use. For further details, refer to the LFE
and/or AR command sections of the IPDS architecture spec.
IPDS Bar Code Printing
To support the BCOCA tower for printing of bar codes, the OCR-A and OCR-B fonts and their
corresponding code pages (892 and 893) must be resident in the printer. These are supported as
shown in page 115 "4028 Compatibility Resident Font Set".
Code page 1303 is also resident to be used for printing code 128 bar codes.
IPDS Font Bolding
The Printer will accept the IPDS Load Font Equivalence command and support the bold and double strike
bits for both resident Type 1 and loaded raster fonts. No other bits within the LFE flags byte are
supported.
The bold/double strike attributes are handled the same way within the printer. The function is provided
by printing a text block multiple times, each time shifted an appropriate amount. Since the attributes are
tied to the font LID and not the font resource, the font resource is not affected.
