Defining Channel Attached Printers Controlled by FSSs

To use the advanced printing functions of the 3800 model 3, you must run it under the control of an output writer FSS. An output writer FSS allows printers to process data containing control characters that format the data as a composed page. Running a printer in this way is known as running it in FSS mode.

You can explicitly define an output writer FSSs or you can let JES3 create a default FSS for each printer. If you want to run a printer under the control of a particular FSS, specify the FSSNAME parameter on the DEVICE statement.

To define the printer to run in FSS mode, define the printer on the DEVICE initialization statement as a shared device and specify the following other parameters:

Use the FSSNAME parameter to specify the installation-defined name of the FSS under which you want the printer to operate. You define the name of the FSS using the FSSDEF initialization statement. If you choose to let JES3 define the output writer FSS, omit the FSSNAME parameter.
Specify the MODE=FSS parameter.
Use the PM (processing mode) parameter to specify the types of data sets that you want the printer to process. Specifying PM=PAGE allows data sets with a process mode of ‘page’ to be printed; specifying PM=(PAGE,LINE) allows data sets with process modes of both ‘page’ and ‘line’ to be printed. The default allows the printer to process both types. You can change the processing mode if the printer is offline and not currently allocated. Use the *F,F operator command with the M= keyword. (See z/OS JES3 Commands for more information on the *F command.)

You should also specify any other required parameters on the DEVICE statement for the specific device.
