I had a Cannon Pixma printer for a year, my flatmate and I shared it for work etc (we worked in the same company) I believe we were using the cannon pixma MP 610.
to answer your question on comparisons of printers there is a decent article on this website (for the nitty gritty details)
http://www.tomshardware.com/reviews/color-laser-printers-2,1534-2.html
In short if you know what you are doing inkjets and laser jets are pretty much the same.
As for the Pixma printers I would have to say we had no issues with our printer, we had 2 (wired desktops), 2 (wireless laptops), and the printer (wireless) running off of a linksys n-router with no hiccups. The printer itself is easy to use and has the usual multi functions; again we never had issues with the wireless network, I am sure you would be pleased if you purchased a pixma printer.
However in closing I would have to say based on your usage is it really a bother wiring your printer?I mean if you are using the printer for a few black and white sheets a day why get another printer? If laying long cables though your home is an issue then there are other alternatives - you can set up a network through your home using your power cables too, the name of the set up escapes me right now, but this link shows you how it works based on something in the UK
