I'm having a hard time deciding between the Xerox Document Centre 4125 and the Canon IR 3110 printers.

I would suggest that you consider what features are important to you in a printer, then compare the specs of each printer. For example, if you need high quality prints, look for one with a higher resolution than the other. If color printing is important, make sure both printers can do it. You should also check customer reviews of the two models and decide which one has better ratings. Finally, think about how much you want to spend on the printer and whether the price difference will be worth it.
