It may be very important to purchase a printer that has a wired network connection. It is not advisable to connect your printer wirelessly.
There’s nothing wrong with buying a printer with wireless printing capabilities, of course, but it’s very reassuring to have a wired connection as well. Wireless printing is still not as reliable as it could be. If you are working on your own in your business, you can connect your printer via a USB cable directly to your own computer.
As your business grows, a wired network connection is not a disadvantage. It would be possible to connect via a wired network from any workstation to print directly.
