To increase the print speed when using Windows, see the tips described in this section.

General tips

Printing color images using higher print quality settings takes longer than printing black-and-white images in standard print quality, since the volume of data in high quality color documents is much greater. For this reason, it is important to be selective in your use of color and print quality settings if you also require a fast print speed.

Even if your document requires the highest print quality and extensive use of color, 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.)

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

*  Varies depending on the printer driver and application software you are using.

Using Speed & Progress

Note:

To enable the Speed & Progress button, open the printer software window as explained in Accessing the printer software for Windows, then click the Utility tab.

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.

High Speed Copies

Select this check box to turn on high-speed printing for multiple copies. This speeds up printing by using your hard disk space as a cache when printing multiple copies of your document.

EPSON Printer Port (For Windows 98 and 95 only)

Select this check box to enable the EPSON printer port, which is optimized for EPSON printers, instead of the Windows default printer port. This speeds up the data transfer rate to EPSON printers.

Show Progress Meter

Select this check box to display the Progress Meter. See Using the Progress Meter for more information.

Check Paper

Select this check box to enable the paper check function, which checks if the paper size and media type settings for the paper tray and printer driver software are the same.

Using DMA transfer (For Windows 98 and 95 only)

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

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

If you need to enable DMA transfer, follow these steps.

Double-click the My Computer icon and double-click Control Panel.

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

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

Click the Resources tab and click the Use automatic settings check box to deselect the automatic setting. Write down the Input/Output Range settings shown in the Resource settings box.

Select a basic configuration setting from the "Setting based on:" list that uses the same Input/Output Range settings as those you wrote down in step 4, and make sure the Direct Memory Access channel and Interrupt Request numbers are allocated and displayed. Confirm also that the Conflicting device list 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 manufacturer for information on the DMA transfer capability of your computer.

Using Port Configuration (Windows NT 4.0 only)

Note:

Port settings for Windows NT 4.0 are complicated and should only be made by experienced personnel with administrative privileges.

If your computer has a parallel port which supports ECP mode, you can make certain print speed settings in the Port Configuration dialog box. Before making settings, make sure that the ECP mode has been selected in your computer settings. For details about ECP mode, see your computer manual.

To access the Port Configuration dialog box, double-click the My Computer icon, double-click the Printer icon, right-click your printer icon, and select Properties. The printer driver window appears. Click the Port tab, then click the Configure Port button.

Click the LPT port tab for the port to which your printer is connected, then click the Port Configuration button.

Note:

If your printer is connected to LPT1, only the LPT1 tab is available.

Resources settings (IRQ and DMA)

If you have connected your printer to LPT2 or LPT3, making IRQ and DMA settings here may help you speed up printing. Input the same configuration numbers for IRQ and DMA which you have made with your expansion board. See your computer manual to determine the settings for IRQ and DMA.

Use DMA transfer

Using DMA transfer to send print data to the computer may help you speed up printing. If the Use DMA Transfer check box appears dimmed, you first need to enable DMA transfer in your computer settings. For details, see your computer manual.
