System Parameters
The
setsystemparams
operator sets the values of the specified system parameters.
This operator requires a password if one is set. The
currentsystemparams
operator
returns a dictionary of the current values of the system parameters.
Values supplied to
setsystemparams
that are outside the range or limits for the
specified integer parameter do not cause
rangecheck
or
limitcheck
errors. An
appropriate value is used. For example, if you set JobTimeout to 14, it is actually set
to 15, and no error is generated. The exceptions are noted in Table 4-10.
Values supplied to
setsystemparams
that do not match the type of the specified
parameter cause
typecheck
errors. Parameters that are not supported by the printer
are ignored. An attempt to change the value of a read-only parameter has no effect on
the parameter. Write-only parameters are not returned by
currentsystemparams
.
To determine which parameters your printer supports, see Table C-4 on page C-10.
