Changing Parallel Port Settings
If you add a parallel adapter or use special hardware or software that causes a
configuration conflict, you might need to change the parallel port settings.
The parallel port can operate in several different modes. The default mode for your
computer is SPP (standard parallel port). However, your computer also supports
the ECP/EPP (extended capabilities port/enhanced parallel port) mode. ECP/EPP
has two advantages over SPP. When your computer is in ECP/EPP mode, you can
print documents faster than when the computer is in SPP mode, and you can attach
devices other than printers, such as communication and storage devices, to the
parallel port. You can set modes of operation for the parallel port using the
Configuration/Setup Utility program.
The parallel port can use any of the following settings:
Ÿ
The three available port addresses are (in hex): 3BC, 378, and 278.
Ÿ
The two available IRQ assignments are: IRQ 7 and IRQ 5.
To change the parallel port settings:
1. Start the Configuration/Setup Utility program (see “Starting the
Configuration/Setup Utility Program” on page 39).
2. Select Devices and I/O Ports from the Configuration/Setup Utility program
menu.
3. Select Parallel Port Setup.
4. Use the arrow keys to select the settings.
5. Press Esc to return to the Configuration/Setup Utility program menu.
6. Before you exit from the program, select Save Settings from the
Configuration/Setup Utility program menu.
7. To exit from the Configuration/Setup Utility program, press Esc and follow the
instructions on the screen.
Note:

Computer.
