Danish consumer organization just test over 50 inkjets. Most expensive
overall was Lexmark, with one having a cost per page of Photo around
$6 for an A4 / Letter sheet.
Average price was around $1, with Canon beeing cheapest, followed
by Epson and HP.
I have a Canon for bulk color prints, a HP laserJet for bulk BW,
and an Epson RX500 all-in-one for Photos.
