IPDS Emulation Mode

Select which type of printer you want IPDS to support. You can choose either to
emulate a 4234 or you can choose 6408/6412. You should choose which mode you
use based on your software applications. For instance, if you are using PSF/MVS,
then you would choose 6408/6412 as PSF/MVS provides support for this printer.
v 4234 (the default). IPDS supports 4234 printer functions. This is the default

are using IPDS with PSF/MVS. This value enables IPDS and PSF/MVS to take
advantage of 6408/6412 printer functions which are supported directly by
PSF/MVS. Other PSF applications only support this printer as a 4234 printer.
