I have been waiting for this for years. I thought of this 5 years ago. But even though the are a lot of pros to the system there are also a lot of cons. You will need to run paper designed for inkjets that costs more because on plain paper the ink runs an you get jagged edges on you print. Ink prints do not have any shine at all, you will have to use gloss paper to get any type of shine on the print. The print heads will not last forever, Canon has the lifetime printheads on their inkjet printers and I can tell you from experience they do not last and they cost about half as much as the printer. My guess is the printheads will be so expensive that when they go it will be time to junk the machine and buy another one. It will also need to be programmed to run a test print daily to keep the ink from clogging the printhead. If the ink is water based it will evaporate even if you are not printing so people that go several days without printing will get very low yield. These are some of the cons I can think of off hand, and I'm sure there will be more, so I don't think we will be out of a job anytime soon.
