5 Using the SIMM for IPDS with a
MarkNet Adapter or MarkNet Print Server
5.1 IPDS in a LAN Environment
When using the SIMM for IPDS in a printer attached to a LAN with the MarkNet S
(Token-Ring or Ethernet) internal network adapter, MarkNet Pro 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
• PSF/2 2.0 (or greater)
• PSF/AIX V2.1 (or greater)
• PSF/400 V3R1 (or greater), V3R6, V4R1, V4R2
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 S, MarkNet
Pro, 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 SCS adapter
(Coax or Twinax attachment) and IPDS hosts connected to the printer
using a MarkNet S, MarkNet Pro, 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.
