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-9.
