I dont have a HP but it might be PCL4. However ghostscript doesn't use many features (at least not on epson-24 pins) it just sends a coded bit image. If most of the page is OK, the problem may be elsewhere - unless the printer is being switched mode every pixel! The second is the comms (eg are you using polled or interrupt - see lptune). A good test is to generate the output data using ghostscript manually to a file (and view the contents of the file if you have a manual to make sense of the escape sequences). Then manually send the file to the printer, using a range of commands cat file > /dev/lp1 -or- dd if=file of=/dev/lp1 bs=1k varying the bs on a monchrome epson gave a 50% speed difference on a polled driver. Also out-of-paper errors (manual feed) gave me a 10 second delay, maybe the language used causes errors that get fed back to /dev/lpt1 that cause errors! If the cable is too long, you may get errors on the line. No answers - just more questions!
