Price: $799. Canon’s A3 inkjet printer is by far the biggest and most expensive of the pack. It offers Ethernet, automatic duplexing, great quality photos and three paper input options. However, there are plenty of downsides too: paper input can be fickle, A4 documents look inky and print speeds are quite slow overall.pson's Stylus Office T1100 A3+ inkjet printer lacks Ethernet connectivity, so it isn't as easy to share between multiple computers as some of the other printers.
