Oh sure, inkjets are "green". Pull the other one, it has bells on it.
From my personal experience :
I've bought Epson inkjet printers. About every two years when I was still using inkjet. Heads clogging, ink drying, etc, as has been said above, I've wasted God knows how much ink on so-called "cleaning" procedures.
Inkjets may be fine, but only at the condition that you are printing many pages every day. If you are printing a dozen pages a month, you're up shit creek without a paddle.
I bought a Samsung laser printer in 2010. It's still working fine, even when I only print a page a month.
Inkjets are green my ass.
