      The IBM LAN Connection for Printers and Plotters provides a direct connection of parallel and EIA-232-C serial printers and plotters to local area networks (LANs).  The IBM LAN Connection for Printers and Plotters consists of a network printer adapter unit that attaches to a LAN and a software utility that resides on the LAN print server.  The adapter unit has both a serial and a parallel port that can be used simultaneously to support two printers or plotters.
       The software utility takes the print data normally sent to the print server's parallel ports and redirects it to either the parallel or serial port of the adapter.  The appropriate printer attached to
the adapter receives the data and prints it just as if the printer were attached to the server's printer port.
       The IBM LAN Connection for Printers and Plotters software utility supports remote printing via an IBM OS/2 (R) Extended Edition (EE) and IBM OS/2 LAN Server for PS/2 (R) server or IBM AIX (R) Version 3.1.5 for RISC System/6000 (TM) (AIX/6000) server that is connected to either a token-ring (IEEE 802.5) or Ethernet LAN.
       The IBM LAN Connection for Printers and Plotters operates without noticeable degradation of printing performance and supports the following data streams: IBM Personal Printer Data Stream (PPDS), Hewlett-Packard Printer Control Language (HP PCL), IBM/HP Graphics
Library (GL), and Adobe PostScript (1).  A user-friendly interface allows the user to easily configure and maintain one or more adapters on the network.
       The IBM LAN Connection for Printers and Plotters supports the following:
o   4033 Model 001 -- Token-Ring (4/16 megabits/second), IEEE 802.5
o   4033 Model 002 -- Ethernet 10BaseT, IEEE 802.3
o   4033 Model 003 -- Ethernet 10Base2 and 10Base5, IEEE 802.3


1333561 Used for -001 / -002
104V to 127V AC, 60Hz
5V DC +/- 5% at 1.5A

1333563 Used for -003 only (BNC Version of 4033)
90V to 265V AC, 50-60 Hz
5V DC +/- 5% (2.0A) 12V DC 

o   IBM 4033 Model 001, Token-Ring:
    -   IBM Token-Ring Network PC Adapter Cable (IBM part #6339098),  if the LAN segment uses IBM Cabling System data grade media and operates at a ring data rate of either 4 Mbps or 16 Mbps.
    -   Type 3 Media Filter Cable, if the LAN segment uses telephone twisted-pair media and operates at a ring data rate of 4 Mbps.
