Graphic designer here. I've used their shitty consumer grade laser and inkjet printers with USB and they have had many problems. I HATE their wide format inkjet printers with a passion..... They work great for a few dozen prints and then decide to have random problems that take a few hours to fix.
Their inkjet Indigo digital presses..... are freaking amazing. The color they produce is far better than any laser digital press I've seen. They required a trained operator and is MUCH more expensive than the shitty consumer level stuff but they last forever when easily maintained.
