Take a look at /etc/cups/mime.types and /etc/cups/mime.convs, and ensure the PDF definitions (there could be 2 or more) and conversion utility are correctly configured. It should be obvious what is needed, as the details are usually in the comments. You will need to do this on all systems running CUPS to/from you wish to print PDF documents. -- Regards, Dave [RLU #314465] == dwn...@ntlworld.com (David W Noon) == signature.asc Description: PGP signature

[gentoo-user] bypassing CUPS - howto
Hi, I'd like to bypass processing by CUPS and send some postscript/pdf file directly to a USB / network printer. Does anybody know how this can be achieved? Many thanks for a hint, Helmut. -- Helmut Jarausch Lehrstuhl fuer Numerische Mathematik RWTH - Aachen University D 52056 Aachen, Germany

Does anybody know how this can be achieved? Why do you need to bypass CUPS? If you have a raw print stream, just ensure you have application/octet-stream enabled. To do this, simply cd to /etc/cups on the machine that owns the printer(s) and edit mime.convs and mime.types. You will easily see the octet-stream support near the bottom of each of these files. -- Regards, Dave [RLU #314465] == dwn...@ntlworld.com (David W Noon) == signature.asc Description: PGP signature

I hope to use pyusb to print to a USB printer. There is a new version 1.0.0a0 on sourceforge. Some of my network printers accept file submission via ftp. But what for the other ones?
