Romeo, the pixelated output has nothing to do with the parallel port connection. The connection works absolutely correct according to your supplied information. Important is to investigate the print filter chain. For that please follow the instructions of the sections "CUPS error_log" and "Capturing print job data" on https://wiki.ubuntu.com/DebuggingPrintingProblems. Thanks.
