Chapter 3 Using the Printer Driver 59
Increasing the Printing Speed
Faster printing with Direct Memory Access (DMA) is possible if
your printer is connected to your computer through an Extended
Capability Port (ECP), a type of parallel port with expanded
specifications. With DMA and ECP, you can send print-job data
directly to the printer without going through the CPU, which
increases the effectiveness of data flow.
Before using DMA to transmit a print job confirm the following
points.
❏
Check if your computer supports DMA. To confirm if your
computer has an ECP chip installed, contact the manufacturer
or look in the computer’s documentation.
❏
Confirm the parallel port setting is “ECP” or “ENHANCED”
through the BIOS Setup. Refer to your computer’s
documentation to set the BIOS. However, before setting the
BIOS, uninstall the EPL-1220 printer driver. After setting the
BIOS, reinstall the printer driver.
Confirming availability of DMA
Using DMA increases your printing speed. You can confirm if
your computer can use DMA by selecting the
Driver Settings
dialog box on the Optional Settings menu of the Properties of
your printer driver.
1. Click Start , point to Settings , and click Printers .
2. Right-click the EPSON EPL-1220 Advanced icon, and click
Properties in the menu that appears.
