Follow this procedure to switch to TCP/IP. It requires that you use the Remote Control Facility to type in a few commands as well as have Desktop Printer Utility at the Macintosh clients.
Note: These instructions are provided for LaserWriter Pro 810 printers with ROM 1.0 installed.
Step One
Obtain a maintenance cable or have one made. See the following Tech Info Library article:
Article 14020: "
LaserWriter Pro 810: Cables for Maintenance RJ12 Port"
Step Two
Connect the maintenance cable to the back of the printer as well as to the serial port on an Apple portable or desktop computer.
Step Three
Use a communications program to create a serial terminal session to the printer. A good example is AppleWorks using the Communications module and setting Communications to Serial Tool. Make AppleTalk inactive or set to Remote Only if necessary.
Step Four
Open a session to the printer. Press the return key a few times. Remote Console Facility will scroll a few lines of text on the screen. (If there is no response, turn off the printer then turn it on again.)
Step Five
Log in under superuser using "su". Password default is "system". You have successfully logged in when the
prompt changes to ">>".
Step Six
Type in the following command to set an IP address:
define server ip <assigned IP address>
Step Seven
To print Postscript files from Macintosh computers to the LPD virtual printer, you must change the Interpreter for this virtual printer. By default, it is PCL. Type in the following command:
set service lpd postscript
Step Eight
Confirm that changes are accepted by typing in this command to restart the printer:
shutdown -r
Step Nine
Upon restart, the printer should print out a Status Page with one page listing all virtual printers. The LPD virtual printer should list "PostScript" as its Interpreter.
Step Ten
At the Macintosh client, open the Desktop Printer Utility and Create a Desktop... for Printer (LPR).
Step Eleven
Click the top Change button to select the PPD file for the LaserWriter Pro 810.
Step Twelve
Click the bottom Change button to make your 'LPR Printer Selection.' In the window that opens, type in:
Printer Address: <assigned IP address for LW Pro 810>
Queue Name: PASSTHRU (this is case sensitive)
Step Thirteen
Save your settings and name your desktop printer file.
Step Fourteen
A Macintosh can now use TCP/IP to print a file to this printer.
