Comment 16 for bug 564917

HP Laserjet 4 printer has only parallel and serial ports. It does not have native USB port. I am using Prolific Technology adapter cable that has parallel connector at one end (which is connected to parallel port on printer) and USB connector at other end (which is connected to computer). This equipment setup previously worked for me on all Ubuntu releases prior to 9.10.

Removing the usblp module did not solve printing problem when HP Laserjet 4 was added as a "parallel" printer, even though it was actually connected via USB adapter cable.

I have also tried connecting HP Laserjet 4 to computer using standard parallel cable that has parallel connectors at both ends. Although printer seemed to be properly recognized and added to system, nonetheless all print jobs would still freeze for hang up in "processing" status. However, this is a different issue or problem and belongs in a different bug report, which I may or may not open as a bug report in the future,

My main concern is to try to get the printer to work with Ubuntu via USB adapter cable. The USB adapter cable offers more flexibility for me because I can also use it to connect to other computer equipment that I have, such as Apple laptop computers that are lacking in parallel ports. So far, I have encountered no problems printing out documents when my Apple laptops, running under the Mac operating system, are connected to the printer via USB adapter cable.
