CHAPTER 4 CONTROL PANEL s Parallel Interface When you use the parallel interface, you need to set the communications mode in the following sub-setting menu. Display Message HIGH SPEED=ON BI-DIR=ON High Speed and Bi-directional Parallel Communications Turns on or off the high speed parallel communications. Turns on or off the bi-directional parallel communications. The above high-speed and bi-directional settings are used for the bi-directional parallel interface of this printer. The bi-directional parallel interface is compatible with the IEEE 1284 standard. Although it uses the same cable, hardware, and software as the bi-directional parallel interface, to use its enhanced capabilities-such as bi-directional communication between the computer and printer and faster transmission of data-you need a printer driver or software that supports these features. Check with your software vendor to see if your software supports bi-directional parallel features. s Serial Interface When you intend to use the serial interface, be sure to select the same communications parameters on both the printer and computer. You must set them for the automatic interface selection, too.
