These are really the types of printers I'm referring to. Any system like the
Riso ComColor,
Kyocera Taskalfa Pro 15000c, or the
iJet envelope printers all use low-quality, high speed memjet-type print heads with aqueous dye/pigment inks. The quality is only good for transactional forms, envelopes, and school classroom handouts. They aren't meant to compete with the quality of toner and offset presses.
I'm referring to systems like the
Konica Minolta AccurioJet 3000, the
Ricoh Pro Z75, and the
Canon VarioPress iV7. These all produce very high quality prints that can compete with offset, and can print on a wider range of substrates. They are all in the B2 size. However, Canon recently announced the
varioPrintiX1700 which handles smaller sheets (14.33" x 26").
