Hi, I am the maintainer of the cndrvcups-lb package. First, I apologise for breaking the thread but i had aur-general mailing options set to digest, so can't reply in thread (changed to single now). After I found out Allen Choong had uploaded the package canon-ufr and this provided the binary counterpart of my cndrvcups-lb (builds from source ) I contacted him and we discussed what name to use for both packages to make it easier for users to see they were alternatives. If you look into the source files, you'll see several things : the downloaded file is called Linux_UFRII_PrinterDriver_Vxyz_uk_EN.tar.gz (xyz = version number) Inside that file are canon supplied deb & rpm binaries. they use names like cndrvcups-common-foo and cndrvcups-ufr2-foo In the sources folder you'll find cndrvcups-common-foo and cndrvcups-lb-foo . When i started work on this package in 2012 there were already several (older) packages for these printers using cndrvcups in the name, so it seemed logical to stick to that. As my package builds from source, I decided to stay close to name canon used for the source files, not the binaries. This lead to cndrvcups-lb and cndrvcups-common-lb. (there was already another cndrvcups-common package in aur that was incompatible with my package). I suggested to Allen Choong we could choose between cndrvcups-lb / cndrvcups-lb-bin and cndrvcups-ufr2 /cndrvcups-ufr2-bin , he was ok with cndrvcups-lb . Lone_Wolf
