This procedure assumes you're using a recent Linux distro with CUPS >= 1.2

1. Download the modified PPD file: Konica-Minolta-C454e.ppd .  This is the PPD from Konica-Minolta with the following lines added to the bottom:

2. *cupsFilter: "application/vnd.cups-raw 0 minolta" *cupsFilter: "application/vnd.cups-command 0 commandtops" *cupsFilter: "application/vnd.cups-postscript 0 minolta"

   This edit sends printed files through a filter called "minolta".

1. Download the minolta filter.  Copy it into the directory /usr/lib/cups/filter and make the file executable (chmod +x).

2. Install the printer in CUPS. Use the new PPD. Then, make a file in /etc/cups/ppd named PRINTER_NAME.km, where PRINTER_NAME is the CUPS name of the printer. In that file, put the following:

   ACCOUNT_NAME="" ACCOUNT_PASSWORD="47235" ACCOUNT_COETYPE="0"

3. Print a test page to make sure everything works.
