DownloadCUPS back-end for the canon printers using the proprietary USB over IP BJNP protocol. This back-end allows Cups to print over the network to a Canon printer. The design is based on reverse engineering of the protocol.
Version 2.0 adds ink-level reporting and improved out-of-paper detection.
Version 2.0.1 is now released under GPLv2 or later to be compatible with the changed cups license. No other changes.
Version 2.0.2 fixes a compile error with GCC9
Version 2.0.3 Fix GCC10 compile errors. increase status buffer size for newer printers that send larger status messages

Very happy with this software. Enabled me to use my Canon MX870 printer with Linux over a wireless connection.

Thanks so much!

On FreeBSD 8.2, the distributed cups-bjnp v0.5.3 ID'ed my Canon PIXMA MP990 via IP4/ethernet, but CUPS gave "Failed to read side-channel request!" Reading here about 5.5, it appears that bugs specific to the MP990 might remain in v0.5.5. So I tried enabling the MP990's optional 'lpr' support and Gutenprint's "Canon PIXMA MP990 - CUPS+Gutenprint v5.2.7" driver started working. Thumbs up and thanks for the effort, but not necessary for this printer.

Got 0.5.4 detecting Canon PIXMA MP980 (initial printer WiFi setup done from Windows) with CUPS 1.4.2 under Gentoo amd64 after creating a symlink from /usr/libexec/cups/backend/bjnp to /usr/lib/cups/backend/bjnp (might be good to update install for this). Now to test the actual printing all I need is to find an amd64 filter/PPD (or setup a 32-bit chroot for cnijfilter hoping it works with MP980).

Absolutely brilliant: does what it says on the tin, has a clear README, and a quick and simple diagnostic check before installation. Thanks so much to the authors; it was considerably less effort for me to install for a Canon MX-850 than for my housemates to install the Windows driver!
