A3 Printer Options
Regardless of your reasons for wanting or at least considering an A3 printer probably the deciding factor will be your budget. It is still quite possible to spend many thousands of dollars on a desk top A3 such as the C9800HDN Color Led Printer which goes for a cool $8200 but there are several on the market suitable for the home office.
For instance you can get the Canon BJC-5100 for under $50 from many retailers and granted, it’s a rather large bulky printer that will require some desk rearranging on your part but the price cannot be ignored and it makes an excellent entry level for anyone wanting to to print larger copies than normal.
