7 Using the SIMM for IPDS with a MarkNet Internal or External Print Server

7.1 IPDS in a LAN Environment

When using the SIMM for IPDS in a printer attached to a LAN with the MarkNet internal print server (Token-Ring or Ethernet), MarkNet Pro external print server (Token-Ring or Ethernet), or the MarkNet XLe print server (Token-Ring or Ethernet), the printer can receive, process and print AFP/IPDS print jobs over TCP/IP from the following IBM software:

PSF_/MVS 2.2 or greater

PSF/2 2.0 (or greater)

NPSF/AIX_V2.1 (or greater)

PSF/400 V3R1 V3R6, V4R1, V4R2, V4R3, or V4R4

The SIMM for IPDS adds support for the non-standard bi-directional TCP/IP PPD/PPR protocol allowing the IPDS data to be transmitted using TCP/IP.

Important: An IPDS host expects to have full control of IPDS resources and settings once it has established communications with the printer. More than one IPDS host may send jobs to a LAN attached IPDS printer. The second host job will be started by the printer after the first host job has been completed and the first host releases the printer. Release of the printer is controlled by the host "release timer" value, the printer IPDS Timeout value, and the MarkNet internal print server, MarkNet Pro external print server, or MarkNet XLe timeouts as specified in the following sections.

On IPDS code level 8223 and above, the IPDS emulation may be shared by IPDS hosts connected to the printer using the Adapter for SCS (Coax or Twinax attachment) and IPDS hosts connected to the printer using a MarkNet internal print server, MarkNet Pro external print server, or MarkNet XLe. When sharing the printer between these types of connections, the IPDS emulation will delete downloaded resources from one host session before beginning another session.
