Printing packages for OpenWrt

This is a package feed aiming at providing a complete printing stack for OpenWrt.

Notably it has:

• Ghostscript 9.52
• Gutenprint 5.2.9
• Cups 1.6.3
• OpenPrinting's cups-filters 1.0.37
• poppler 0.24.1
• many other packages to make sure the ones above work...

To use this feed,

• set up your router to use external storage for its root file system, as these packages require more than a 100 MB of space.

• set up a [cross-compilation environment] [cross-compilation environment]: http://wiki.openwrt.org/doc/devel/crosscompile

• add this line to your feeds.conf or feeds.conf.default

src-git printing https://github.com/belphegor-belbel/openwrt-printing-packages.git

• to compile everything in this feed you should use the script setup-buildsystem.sh or some variation of those commands.

• copy compiled packages to your router (copy the whole directory as you need the files used to index the packages)

scp -r ./bin/$ARCH/packages root@openwrt.lan:/storage/printer/packages/

• add local package source to the opkg configuration /etc/opkg.conf with

src/gz printing file:/storage/printer/packages

• see opkg-install-printing-packages.sh to see a suggestion of what to install.

• tested against Attitude Adjustment (because that is what I have installed...).

• Avahi is notified of printers added to Cups, and these will appear as Air Printer's in iOS devices.

Issues / Missing / TODO

Caveat: Ghostscript lacks proper cross-compilation support. I used a patch taken from timesys.com. If your architecture is not there, compiling it just won't work for you.

The alternative for those who can't compile Ghostscript is to use a different PDF backend, in this case Poppler. For instructions of how to do this open the tar-ball of the cups-filters-*.tar.bz2 and check the section 1. Selection of the renderer: Ghostscript, Poppler, or Adobe Reader of the README.
