Which drivers are you using ? How did you go about installing it exactly ?
it says hpijs/hplip drivers work best.
Sorry to hear that about the yikes ... that's quite tragic
... I hope he gets better.
EDIT: What I would do is:
1) Download the hpijs ppd file here
2) gunzip it so it is Brother-HL-1430-hpijs.ppd.gz
3) copy it into '/usr/share/ppd'
4) restart cups like this '/etc/rc.d/rc.cups restart'
5) make sure the printer is on, and try adding it again on here:
