HP Designjet 455CA/488CA Printers - MacOS: Connecting to a Macintosh

Issue:
How do I connect the HP Designjet 455CA and 488CA printer to a Macintosh computer?
Solution
Connect an HP Designjet 455CA and 488CA printer to a Macintosh in the following manner:
Required accessories
  • HP Jetdirect EX Plus external printer server (HP part number J2591A)
  • HP IEEE-1284 compliant Bitronics parallel cable (HP part number C2950A)
  • 10 Base-T Crossover Ethernet cable (HP part number C6080-60015), or a standard 10 Base-T Ethernet cable.
  • DC Power converter
Steps for connecting to a Macintosh
  1. With the HP Designjet 455CA and 488CA printer and Macintosh computer disconnected from the power supply, connect the HP Jetdirect EX Plus print server using the Bitronics cable supplied with your printer.
  2. Connect the HP Jetdirect EX Plus print server to your network using either the 10Base-T or BNC connector and the appropriate cable. See below:
      note:
    If connecting the HP Jetdirect EX Plus print server directly to a Macintosh, use the "crossover cable" supplied with the printer.
    If connecting the HP Jetdirect EX Plus print server to a hub, use a normal 10Base-T twisted Ethernet cable (not supplied with the printer).
    If connecting the HP Jetdirect EX Plus server to a MAU (using a co-axial cable), use a normal BNC cable (not supplied with the printer). Be sure to use T-connectors, and to terminate both ends with 50 ohm resistors.
  3. Connect the DC jack plug of the DC power converter to the HP Jetdirect EX Plus server.
  4. Connect the DC power converter into the main power supply. The "status" light indicator of the HP Jetdirect EX Plus server box should begin to flash indicating that the printer is properly connected. The "status" light will then go steady and the "activity" light may or may not flash, depending upon your network connection.
The HP Designjet 455CA and 488CA printer can be switched between HPGL and HP/GL2 language using the Setup Page. The printer default is HPGL, the Macintosh RIP, Jet Direct EX box, and the Designjet may function better when the printer is set to the HP/GL2 language. See the User’s Guide for details on the Setup Page.
