    GENICOM LN28 and microLaser 280 User Guide Connecting the Printer to the Host Computer Connecting the Printer to the Host Computer You must connect the printer to your computer using an IEEE 1284 parallel cable or a USB cable. These cables are user-supplied, the printer does not include either of these cables. The parallel and USB ports can not be used simultaneously, and the default configuration of your printer has the USB port turned off.

  • Page 33: Usb Port

    If you are using one of these operating systems, your PC may require an optional upgrade to work properly with USB. This upgrade is called USBSUPP.EXE and is provided in the \OTHER\USB directory of your Windows 95 CD-ROM. GENICOM does not supply this update. To find out if your hardware/operating system combination supports USB, run the free program USBREADY.EXE, available from www.usb.org.
  • Page 34 USB hardware, have an obsolete USB implementation . Your GENICOM USB printer will not work with these older systems unless a separate USB controller card is installed in your system. It is possible to have working hardware but not have a physical port, in which case the proper connector must be purchased from the system supplier.
  • Page 35 The keyboard USB port on an iMac can only source a minimal amount of power. Plugging a bus-powered device into this port can cause problems because of insufficient power. Since the GENICOM USB Printer draws no power from the bus, it should be possible to use this port without affecting other USB devices.
