While contemplating buying a much larger, way more expensive Canon or Epson or Hp.(for the larger, more economical ink carts.)....I wondered if anyone has figured a way to put larger inkcarts in the venerable HP B9180...which has been known to make some pretty decent 13x19" prints. The largest and only ink carts available are 28 milliltre pigment "Vivera" units, and sell now at about $ 41. inc. Ca. sales tax....if ya do the math, you can see why I wanna get a big Epson or Canon with huge ink carts ...but may wanna take a 2nd look at "mcGyver ing" some larger ink carts on to this rig. Anybody done something with this printer like this?? I am presently "stuck" with the B9180.
