The default configuration file of CUPS already has the raw data uncommented by default. From http://www.gentoo.org/doc/en/printing-howto.xml#remote_usage: Enable Support for Windows PCL Drivers PCL drivers send raw data to the print server. To enable raw printing on CUPS, you need to edit /etc/cups/mime.types and uncomment the line application/octet-stream. Then you need to edit /etc/cups/mime.convs and uncomment the line containing application/octet-stream. Code Listing 3.7: Enable support for raw printing # vim /etc/cups/mime.types (Uncomment the line so that the file contains:) application/octet-stream # vim /etc/cups/mime.convs (Uncomment the line so that the file contains:) application/octet-stream application/vnd.cups-raw 0 - Do not forget to restart CUPS after making changes to /etc/cups/cupsd.conf by running /etc/init.d/cupsd restart
Fixed in CVS, thanks for reporting.
