48Enabling High Speed Printer CommunicationsYour Xerox WorkCentre XD Digital Copier/Printer has been designed to provideexcellent copy and print quality with high productivity. To ensure the highest printperformance, the Xerox WorkCentre XD Digital Copier/Printer was designed totake advantage of high speed parallel port communications between your personalcomputer and your Xerox WorkCentre XD Digital Copier/Printer. This can beaccomplished by enabling the Extended Capabilities Port (ECP) mode for yourpersonal computer parallel port (LPT1, LPT2 etc.).What is ECP?ECP is a particular type of personal computer interface for printers that wasestablished by the IEEE-1284 standard. Personal computers with this type ofprinter interface can enable printing up to four times faster than personalcomputers without ECP.How do you know if ECP is enabled on your computer?Many computers will give a status of the printer port settings through theWindows™ control panel and printer settings folders. Others may give the statusby special software on the personal computer to view BIOS settings or CMOSsettings. When you install the Xerox WorkCentre XD Digital Copier/Printer driversoftware on your personal computer, the install software will automatically checkyour personal computer for you. If your personal computer is not running in ECPmode, the driver software will remind you that higher printing performance wouldbe achieved if ECP were enabled.How will your printing performance be affected if you do not have an ECPcompatible personal computer, or if you do not enable ECP mode?Since the rated print speed of the Xerox WorkCentre XD Digital Copier/Printer hasbeen verified with ECP mode, the only effect you may notice is a slight reduction inthe print speed.Are there any other requirements for ECP mode?Always use an approved IEEE-1284 compliant cable (as the one supplied withyour Xerox WorkCentre XD Digital Copier/Printer). Never use (scanners, CDdevices, tape drives, switch boxes, etc.) attached to the same port as the XDseries operate. Each device should be on a separate parallel port (LPT1, LPT2etc.) for the greatest reliability.What can you do if your personal computer does not appear to have ECPmode enabled?1) Check your personal computer documentation for a description of this feature.Particularly look for BIOS and/or CMOS settings, etc.2) Call your personal computer’s manufacturer. Be prepared with the modelnumber and serial number.3) Contact a computer sales or service near you, and inquire about an ECP boardoption for your personal computer that will allow your personal computer tooperate in this mode.
