Canon's older laser mfps do not support Mac printing; hopefully the Gutenberg drivers helped. If not, and you need to replace, the newer models will work. Look for the MF4000 series (MF4150, 4270, et al) which is about the same size as your 3110, or for heavy duty office use, the larger MF6500 series. The current models won't scan to a Mac, but it's lo res anyway. The newer ones that were just announced may.
