This because I fixed the interrupt handling of lp some days ago. Before
2.1.9? (I don' t remeber the exact release that apply my lp patch) the lp
interrupt printing was mainly polled for my stupid error. That wasn' t a
big bug but lp didn' t take the full interrupt advantages and so the load
of the CPU pratically was the same of a polled printing while now an
interrupt printing load only the 0.xx % of the CPU. Now the interrupt
printing works fine (as in 2.0.3x) and if your printer don' t work using
interrupt it should be buggy. Can you print using interrupt in other
operating system?
