Hi Michael, I am printing postscript files. Used 'magicfilterconfig' to configure it. Just changed the resolution from 300 to 600 in /etc/magicfilter/... I had another off-list answer to this question. Ben told me to check http://www.linuxprinting.org/show_printer.cgi?recnum=62816 and I discovered that this printer is very slow with ghostscript versions prior to 5.50 "potato" gs is 5.10, so I changed this printer to another machine that is "woody" (gs 5.50) and it worked very fast. I think gs 5.10 uses PCL4 to send data and gs 5.50 uses PCL5, that supports some compactation while sending the data. > > It seems that the faster driver implements some data compression and > > data is sent quickly to the parallel port.
