Ipds Emulation Mode - IBM 6400 Programmer's Reference Manual

Low (Default) Accepts images with 144 by 144 and prints images at 120
by 144. With this setting, the image is converted from 144
by 144 to 120 by 144. Since there is some conversion
required, there may be some differences between the
original image and the printed image. Review the note
below for more information.
Note: There is one bit of image data per pel. If your print job contains an image
created to print 144 by 144, which is very common for IBM 4234 printers, some
bits of data will be dropped out to support the best fit resolution, which is 120 by
144.
When printing jobs with images created for an IBM 4234 printer, you will want to
print a few samples to ensure the results are satisfactory.

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. 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 as PSF/MVS provides support for this printer.
Note: You can only use IPDS Emulation Mode with a coax interface.
4234 (Default) IPDS supports 4234 printer functions. This is the default
which should be used most often. If you are using IPDS
with PSF applications, except PSF/MVS, make sure you
select 4234.
Please review Chapter 3, "IPDS Commands Reference" on
page 23 for information on using IPDS commands when
you select 4234 from the IPDS Emulation Mode menu.
6408 IPDS supports 6408 printer functions. Use this value when
you are using IPDS with PSF/MVS. This value enables
IPDS and PSF/MVS to take advantage of 6408 printer
functions which are supported directly by PSF/MVS. (Other
PSF applications only support this printer as a 4234
printer.)
Please review Chapter 4, "IPDS Command Differences" on
page 135 for information on using IPDS commands when
you select 6408 from the IPDS Emulation Mode menu.
Note: If you want to use the value 6408 as the default value, you will need to
select 6408 as the default, save the value as a custom set, and then power the
printer off and then power the printer back on.
