Device Parameters
The currentdevparams operator returns a dictionary of the current values of the
system parameters.
The setdevparams operator sets the values of the specified device parameters.
•
This operator requires a password if one is set.
•
Values supplied to setdevparams that are outside the range or limits for the
specified integer parameter do not cause rangecheck or limitcheck errors.
The appropriate value is used.
•
Values supplied to setdevparams that do not match the type of the specified
parameter cause typecheck errors.
•
If a parameter name is not known, an undefined error occurs.
•
An attempt to change the value of a read-only parameter has no effect on the
parameter.
•
To specify the parameters for a specific communications channel, use the
appropriate suffix. For example, the serial channels are:
– %SerialA%
– %SerialB%
– %SerialC%
– %SerialD%
For some printers, no “A” channel exists. If %Serial% is specified, it refers to the
channel where the print job is sent.
