VARIABLES Category
The INFO VARIABLES command returns a list of the
environment and printer language-dependent variables.
Use this command to find a list of the variables, the current
setting for each, and the possible values.
The set of printer language-specific variables returned by
the printer depends on the current environment and the
printer languages installed. Each add-on printer language
has its own specific variables. Printer language-specific
variables are always indicated by LPARM:personality in the
response. Port-specific variables (HP LaserJet 4PJ only) are
always indicated by IPARM:port in the response.
One portion of the returned information is a list of font
sources (see the following example). This list varies
depending on which font sources, such as ROM SIMMs and
cartridges, are installed. Only those font sources which are
installed and contain valid fonts appear on the list. For
example, the S option appears only if one or more
permanent soft fonts currently exist.
The FONTNUMBER range lists the range of fonts for the
current font source only. The lower limit is 0 if the current
font source contains a default-marked font; otherwise the
lower limit is 1. The upper range limit varies depending on
how many fonts are in the current font source.
Note
For information about any of the environment variables
listed by the INFO VARIABLES command, see the
"Environment Variables" section in Chapter 6.
