Media origin

The Printer Inventory or Exit 7 can aid in migrating from a 3800 printer to a 3835 or 3900 printer by setting the media origin of the destination printer to match that of the 3800 printer. The location of the media origin is one of the main differences between the 3800 and other AFP continuous-forms printers. For information about the media origin a printer supports, see the documentation provided with the printer.

When you are migrating 3800 print jobs, you can provide a compatible media origin by including the proper presentation options in the form definition for each job. Alternatively, you can tailor the Printer Inventory or Exit 7 to enforce a 3800-compatible form origin for any designated job.

Note: The media origin override is only offered as a migration tool to aid the user in migrating from a 3800 to a more recent printer. As applications are developed or modified to take advantage of new functions, the work must be done to remove the need for the 3800 origin override. Jobs that are designated by this override must not specify capabilities that are not supported by the 3800 printer, such as N_UP, Page Modification Controls, Post-processing controls, Presentation System Setup IDs, or Presentation Fidelity Controls. If, for example, N_UP is specified in the form definition of a job that is designated as 3800-compatible, the 3800-compatible override is ignored. PSF processes the job by using the N_UP capabilities of the 3900 or 3835 printer to which the job is sent, but issues a warning message that notes the conflict between the override and the form definition.

If the media origin is set for a job that is routed to a cut-sheet printer or routed to a continuous-forms printer that does not support changeable media origin, the media origin is ignored, but no message is issued.

You can use the Printer Inventory or Exit 7 to control whether to set the media origin to the 3800 media origin (see Table 1):

Table 1. Setting media origin options
Printer Inventory	Exit 7	Description
Set media origin to 3800 origin for: Data set	XTP738MO	Controls whether to set the media origin to the 3800 media origin.
Set media origin to 3800 origin for: Data set header	XTP7DHMO	Controls whether to set the media origin to the 3800 media origin.
Set media origin to 3800 origin for: Job header	XTP7JHMO	Controls whether to set the media origin to the 3800 media origin.
Set media origin to 3800 origin for: Job trailer	XTP7JTMO	Controls whether to set the media origin to the 3800 media origin.
Set media origin to 3800 origin for: Message data set	XTP7MDMO	Controls whether to set the media origin to the 3800 media origin.

These options default to NO, which specifies that PSF is not to set the media origin to the 3800 media origin. If any option is set to YES, PSF sets the media origin to the 3800 media origin for that particular page or pages.

If you set one or more of the 3800 media origin options, use wide paper on the 3800, and use cut-sheet emulation, the media origin is not in the correct position. PSF assumes narrow paper (portrait pages are generated for printing in cut-sheet emulation mode).

You can also use the Printer Inventory or Exit 7 to control whether PSF sets the media origin for wide or narrow paper (see Table 2):

Table 2. Setting media origin for wide or narrow paper
Printer Inventory	Exit 7	Description
CSE orientation	XTP7WIDE	Controls whether to print portrait or landscape pages when you are using cut-sheet emulation and 3800 media origin.

This option defaults to NO, which specifies that PSF is to print portrait pages. If the option is set to YES, PSF assumes wide paper and prints landscape pages. This option is only valid when you are using cut-sheet emulation with one or more of the 3800 media origin flags set in the Printer Inventory or Exit 7.
