POST Sequence, LAN Connected

Power up the 4033 while it's connected to the LAN (or use the Reset Button). The following sequence should occur:

  1. Power LED turns On solid
  2. Print LED:
    1. Blinks several times in about 3 to 4 seconds
    2. Turns Off (blank) for up to 30 seconds
    3. Turns On (solid)

If both LEDs are NOT on after the 4033 completes POST, or the above sequence is not completed, then go to LED Sympom Index After Post.


The IBM LAN Connection for Printers and Plotters [4033] provides a direct connection of parallel and EIA-232-C serial printers and plotters to LANs. The 4033 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 utility redirects print data to the 4033's parallel or serial port. The printer attached to the 4033 receives data and prints it just as if it was attached to a server's printer port.

The software utility supports remote printing via an OS/2 Extended Edition and LAN Server for PS/2 server or AIX Ver 3.1.5 server connected to token-ring or Ethernet LAN.

The 4033 operates without noticeable degradation of printing performance and supports: IBM PPDS, HP PCL, IBM/HP GL, and Adobe PostScript (1).

LAN Cabling Requirements

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.
