If you have more parallel products than you have ports or if your parallel
port does not support ECP, consider buying an ECP card for your computer.

in your HP OfficeJet Pro Utilities program group/folder contains a list of
recommended ECP cards.

As part of the software installation process, a test is performed to confirm
communication between your PC and the HP OfficeJet Pro 1150C. Results
of the test will be presented on your PC monitor. If the bidirectional
communication test fails, it is highly recommended you read important
information about bidirectional communication and ECP in the ECP
document that is located in your HP OfficeJet Pro Utilities program group/
folder.
NOTE
If bidirectional communication is not established during the communications
test, you must manually set the front panel language and paper size. Refer
to “Change the Front Panel Language” in Chapter 2.
