Increasing the Print Speed

Using Speed & Progress
Using Port Configuration (Windows NT 4.0 only)

Printing color images using higher print quality settings takes longer than printing black-and-white images with normal print quality, because the volume of data in a high-quality color document 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 faster 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).

Using Speed & Progress

You can make certain print speed settings with the Speed & Progress dialog box. To access this dialog box, click Speed & Progress on your printer software's Utility menu.

High Speed Copies

Turn this on to print multiple copies of your document faster.

Show Progress Meter

Turn this on to display printing progress while printing.

EPSON Printer Port (For Windows 95 and 98 only)

Turn this on to speed up the data transfer rate to EPSON printers.

Enable DMA transfer (For Windows 95 and 98 only)

If your computer has a parallel port which supports ECP mode, you can enable DMA transfer to help you 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 setting 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 maker 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 driver using Add/Remove Programs in the Control Panel. After running the BIOS Setup program, reinstall the printer driver.  

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

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

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

3. 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.

4. 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.

5. 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.

6. Click OK to save the settings.

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

images/note.gif 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.

Using Port Configuration (Windows NT 4.0 only)

images/note.gif Note:
Port settings for Windows NT 4.0 are complicated and should only be made by a qualified person with administrative privileges.

If your computer has a parallel port which supports ECP mode, you can make certain print speed settings with 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.

images/note.gif 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 is dimmed, you first need to enable DMA transfer in your computer settings. For details, see your computer manual.
