45Enabling High Speed PrinterCommunicationsYour Xerox WorkCentre has been designed to provide excellentcopy and print quality with high productivity. To ensure thehighest print performance, the Xerox WorkCentre was designedto take advantage of high speed parallel port communicationsbetween your personal computer and your Xerox WorkCentre.This can be accomplished by enabling the ExtendedCapabilities Port (ECP) mode for your personal computerparallel port (LPT1, LPT2 etc.).What is ECP?ECP is a particular type of personal computer interface forprinters that was established by the IEEE-1284 standard.Personal computers with this type of printer interface can enableprinting up to four times faster than personal computers withoutECP.How do you know if ECP is enabled on your computer?Many computers will give a status of the printer port settingsthrough the Windows™ control panel and printer settingsfolders. Others may give the status by special software on thepersonal computer to view BIOS settings or CMOS settings.When you install the Xerox WorkCentre Digital Copier/Printerdriver software on your personal computer, the install softwarewill automatically check your personal computer for you. If yourpersonal computer is not running in ECP mode, the driversoftware will remind you that higher printing performance wouldbe achieved if ECP were enabled.How will your printing performance be affected if you do nothave an ECP compatible personal computer, or if you do notenable ECP mode?Since the rated print speed of the Xerox WorkCentre DigitalCopier/Printer has been verified with ECP mode, the only effectyou may notice is a slight reduction in the print speed.Are there any other requirements for ECP mode?Always use an approved IEEE-1284 compliant cable (as the onesupplied with your Xerox WorkCentre Digital Copier/Printer).Never use (scanners, CD devices, tape drives, switch boxes,etc.) attached to the same port as the WorkCentre operate.Each device should be on a separate parallel port (LPT1, LPT2etc.) for the greatest reliability.
