Enabling High Speed Printer Communications - Xerox WorkCentre XL2120 User Manual

Enabling High Speed Printer
Communications
Your Xerox WorkCentre has been designed to provide excellent
copy and print quality with high productivity. To ensure the
highest print performance, the Xerox WorkCentre was designed
to take advantage of high speed parallel port communications
between your personal computer and your Xerox WorkCentre.
This can be accomplished by enabling the Extended
Capabilities Port (ECP) mode for your personal computer
parallel port (LPT1, LPT2 etc.).
What is ECP?
ECP is a particular type of personal computer interface for
printers that was established by the IEEE-1284 standard.
Personal computers with this type of printer interface can enable
printing up to four times faster than personal computers 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 the Windows™ control panel and printer settings
folders. Others may give the status by special software on the
personal computer to view BIOS settings or CMOS settings.
When you install the Xerox WorkCentre Digital Copier/Printer
driver software on your personal computer, the install software
will automatically check your personal computer for you. If your
personal computer is not running in ECP mode, the driver
software will remind you that higher printing performance would
be achieved if ECP were enabled.
How will your printing performance be affected if you do not
have an ECP compatible personal computer, or if you do not
enable ECP mode?
Since the rated print speed of the Xerox WorkCentre Digital
Copier/Printer has been verified with ECP mode, the only effect
you 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 one
supplied 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, LPT2
etc.) for the greatest reliability.
