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. This will be helpful especially if you do much scanning. The ECP document in your HP OfficeJet Pro Utilities program group/folder contains a list of recommended ECP cards.
Communication Test
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.
