Sharp also make great commerical-grade printers that are 100% Linux compatible, we’re using these at work: http://global.sharp/products/copier/products/bp_70c65/index.html
They don’t really make anything small enough to be a “home” model, this looks like their smallest printer: https://global.sharp/products/copier/products/mx_c358f/index.html (and that’s around $1000, if you could even find someone to sell you one).
Interestingly, looking at Gentoo’s package, they have both the github and tukaani.org URLs listed:
https://github.com/gentoo/gentoo/blob/master/app-arch/xz-utils/xz-utils-5.6.1.ebuild#L28
From what I understand, those wouldn’t be the same tarball, and might have thrown an error.
