I noticed someone mentioned HP OfficeJet's. I have a J4580, which is not supported under Centos-5.5. (In fact, very few OfficeJet's seem to be supported.)
However, Dag Wieers pointed out that one has to install the latest hplip (together with hpijs and libsane) from http://packages.sw.be/hplip/.
I did this, and find the OfficeJet works perfectly now under CentOS.
Yes, HP *InkJets* need 'bleeding edge' 'drivers' (which are really just means that the additional model *names* have been added to the 'driver'), along with the needed .ppd files for the new printers. I don't think the new printers require any new actual *code* -- they all use the same basic raster format and the same basic driver protocol (they all use the same GS ijs rasterizer).
