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.
