Pros: Compact Design, Lightweight/Portable, Easy Setup, easy to use
Cons: Slow Print Speed, High Ink Consumption, unreliable
I have used an iP1800 extensively over the last 3 or 4 months. While it's simple to set up and use, I find the ink consumption to be extremely high. Paper seems to never feed straight, so all printing is slightly crooked. Certain high-gloss, Canon papers, which I've used for printing certificates, smeared horribly during printing, making them embarrassingly unusable for my workshop graduates.
Overall, a huge disappointment and an unbelievable step down from my ancient BJC-210J (purchased in Japan many, many years ago).
