This article discribes the communication switch settings on the LaserWriter IIf and LaserWriter IIg printer.
DISCUSSION The LaserWriter IIg contains an ethernet port, the LaserWriter IIf does not, so when the chart indicates ethernet, it only applies to the LaserWriter IIg printer. The following table shows the communication settings in effect when the printer is new. The push-button switch on the printer's connector panel can be set to positions 0-9. Switch positions 0-5 are fixed, and the settings for these positions cannot be changed. Positions 6-9 are user-configurable; you can change the settings for these positions to match the needs of the computer you are connecting. The section "Available Settings," at the end of this article, lists all the options available for each setting. From a Macintosh computer, you use the LaserWriter Utility program to display and change communication settings. From a computer other than a Macintosh, you can send PostScript commands to the printer to change the communication settings.
