Abstract

Disclosed is a method which allows System/370* (S/370) host users to send data to a Local Area Network (LAN) printer. The printer is managed by a LAN file server that is channel-attached to the S/370 host.

Down Stream Printing in a LAN Environment

      Disclosed is a method which allows System/370* (S/370) host
users to send data to a Local Area Network (LAN) printer.  The
printer is managed by a LAN file server that is channel-attached to
the S/370 host.

      "Down Stream Printing" allows a great variety of Personal
Computer (PC) based printers to be supported in a distributed office
environment.  The user's PCs are connected to LAN file and print
servers that are located near their work place, not in a central,
possibly distant, building.  Down stream printing lets the S/370 user
direct his print data to any of these local print servers.  There are
several advantages to this scheme over traditional host-attached
printers:

o   User convenience
o   Data security
o   Better turn-around time
o   Greater variety of printer types

      This disclosure describes how IBM LAN Resource Extension and
Services/VM (LANRES/VM), IBM Program Number 5684-142, embodies Down
Stream Printing.  (LANRES/VM provides a interface to the S/370 user
for receiving print files and sending them to channel-attached
NetWare** file servers.

      In the figure, the Down Stream Print (DSP) Virtual Machine (VM)
on the S/370 host waits for print files from the S/370 users.  The
User sends the print file to the DSP VM using the normal VM system
spool.  Users on remote S/370 hosts can also send print files via a
wide area network, such as Remote Spooling Communications Subsys...
