(Either the parallel card, or the cable is dropping the /ACK signal.) By fixing the hardware, you will gain another 5 times in printing speed. (Been there, done that. After being too lazy to open the case for placing the jumper, i've attempted to use the driver in polled mode first, but resorted to true interrupt mode rather quickly.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
