network printing

[kinmun]

I have a web application for customers to order food & beverage items through a mobile app.

the web application is sitting on the DMZ segment.

printing of orders is to be done through printers in the LAN print/print server.

Can this work ?

DMZ web appication through tablets/smartphones -> LAN printer 

normal printing protocols like smb, tcp/udp 137/138.

or can i do wireless printing

Certainly... assuming customers can get to the DMZ web app, you'll just need to allow your DMZ IP to your LAN printer IP over whatever protocols you need for your print server. 

Wireless is irrelevant, unless wireless traffic doesn't go through the Firewall.

Network printing is such a useful feature, especially for offices or homes with multiple devices. In my recent blog, I shared some simple insights about how it works and why it saves so much time. Along with that, my site also covers updated Mixue menus and food prices, a mix of tech tips and dining info all in one place. It’s always fun to explore both sides!
