I'm definitly no expert, but I do miss the HP K5000 (or something like that) I had some years ago - the colors could be changed separately and it printed A3 (about 2 x letter).. at the moment I only have a normal table top printer, and thats anoying when you want to print maps... need more size... !
*in scottish accent*... I'm givin ya all the size she can handle captain....

also had a Canon MP500 a year ago - really good... until it broke
