Resource Memory Management
Axis AFP is equipped with 700 kbytes of resource memory in which fonts, overlays
and page segments are stored to be transmitted to the printer when requested. The
PS VM Size parameter defines how much printer memory is available for Axis AFP
to use. When the printer memory limit is reached, unused resources are deleted
from the printer.
The minimum value of the PS VM size parameter is 200 kbytes. If down-loaded
fonts are used, this parameter has to be increased. The default value is 1200 kbytes,
corresponding roughly to the 700 kbytes available RAM in the Axis AFP.
The PS VM size parameter is printed on the lower half of the power-on page. It is
important that this value is lower than or equal to the actual PostScript VM Size
of the printer which is printed on the upper half of the power-on page.
Characters and Code Pages
The resident font characters offered are those in the PostScript character set (ISO
8859-1 and Symbol) with added cursor line-draw characters. To evaluate the char-
acters offered, use Function Mode option ‘2’, EBCDIC Character Table, to print
the character table.
See also Appendix B, EBCDIC Character Table, for the US English Code Page
37 EBCDIC character table characters.
The code pages supported are those in the US Language Group. A list of code pag-
es can be found in Appendix A, #50 System Language.
For host down-loaded fonts, all characters and code pages are supported.
Resident Fonts
The Axis AFP uses the resident fonts in the attached PostScript printer, supple-
mented with the OCR-B and Letter Gothic outline fonts (down-loaded from the
Axis AFP when needed). The PostScript font is scaled to be functionally equiva-
lent to the corresponding selected IBM font.
In addition, up to 128 user fonts can be defined to map to any PostScript font in
the printer.
See section 5, Fonts, for a listing of to which PostScript font a certain IBM printer
resident font is matched.
