Increasing the Print Speed

General tips
Using the Speed & Progress dialog box

Follow the instructions in this section to increase the print speed of your printer.

General tips

Just as printing at a high resolution requires more processing time than printing at a low resolution, printing in color takes longer than printing in black-and-white because the volume of data in a color document is much greater. For this reason, it is important to be selective in your use of color printing if you also require a fast print speed.

However, even if your document requires the highest resolution and extensive use of color — for example, when you are printing a camera-ready composite that includes color photographs — it may still be possible to optimize the print speed by adjusting other printing conditions. Keep in mind that changing some conditions to increase the print speed may also lower print quality.

The following table shows the factors that inversely affect print speed and print quality (increasing one will decrease the other).

Print quality Print speed		Lower Faster	Higher Slower	Printer software menu
Printer software settings	Paper & Quality Options	Economy, Normal	Photo	Advanced dialog box
Printer software settings	High Speed	On	Off	Advanced dialog box
Data characteristics	Image size	Small	Large	-
Data characteristics	Resolution	Low	High	-

The table below shows the factors related to print speed only.

Using the Speed & Progress dialog box

You can make certain print speed settings in the Speed & Progress dialog box. Click the Speed & Progress button on your printer software's Utility menu. The following dialog box appears.

The available settings that are related to print speed are as follows:

High Speed Copies

To print multiple copies of your document faster, select High Speed Copies. This speeds up printing by using your hard disk space as a cache when printing multiple copies of your document.

EPSON Printer Port (Windows Me, 98,and 95)

For printer models that use the parallel port, select this check box to enable the EPSON printer port optimized for Epson printers, instead of the default Windows printer port. This speeds up the data transfer rate to Epson printers. Parallel port users can further increase print speed by enabling DMA transfer, as explained below.

Enabling DMA transfer

If your computer has a parallel port that supports ECP mode, you can enable DMA transfer to speed up printing. See your computer manual to determine if it supports ECP mode and DMA transfer.

To determine whether you need to enable DMA transfer, compare the message below the EPSON Printer Port check box to this table, and take the recommended action.

Message	Action
High Speed (DMA) Transfer enabled.	DMA transfer is already enabled. Click OK to close the dialog box.
For higher data transfer rates, use DMA Transfer.	Follow the steps below this table to enable DMA transfer.
(No message)	Your system's parallel port setting does not allow DMA transfer. However, if you change the parallel port setting to ECP or Enhanced using your computer's BIOS Setup program, you may be able to use DMA transfer. Consult your computer manual or computer manufacturer for instructions. Once you change the parallel port setting, follow the steps below this table to enable DMA transfer. Note: Before you run the BIOS Setup program, uninstall the printer software using Add/Remove Programs in the Control Panel. After running the BIOS Setup program, reinstall the printer software.

If you want to enable DMA transfer, follow the steps below.

Double-click the My Computer icon on your desktop, then Control Panel.

Double-click the System icon, and then click the Device Manager tab.

Double-click the Ports (COM & LPT) icon, then the LPT1 icon. If your printer is connected to a port other than LPT1, double-click the appropriate port icon.

Click the Resources tab, and then clear the Use automatic settings check box. Write down the Input/Output Range settings shown in the resource settings box.

From the Setting based on list, select a basic configuration setting that uses the same Input/Output Range settings as those you wrote down in Step 4, and make sure that the Direct Memory Access channel and Interrupt Request numbers are allocated and displayed. Confirm also that the Conflicting device list text box shows No conflicts.

Click OK to save the settings.

Reopen the Speed & Progress dialog box to verify whether DMA transfer has been enabled.

Note:

You may not be able to use DMA transfer on some computers even after you make the settings explained above. Consult your computer maker for information on the DMA transfer capability of your computer.
