Q: If I have an LPD printer with IP Address 10.x.x.x, Can I print to this when I'm not on the network?

Where do you want to print from, the Internet? 10.x.x.x addresses are non routable private addresses. More details please.

You would need to establish a VPN connection to the network it is on when you are not, speak to your business IT dept, they may not allow it but it can be done.

Any address beginning 172, 192 or 10, these are private addresses, my network begins 10.xxx.xxx.xxx, as do thousands of others, they are local networks (LAN) as opposed to internet accessible addresses (WAN). Without them there would not be enough addresses for all of us.

But you can access them over a VPN, not technically difficult but businesses want to control who can get into their networks. So you need permission and a VPN to get in. Then you can print to the printer in your office.

Set up and use Back to My Mac - Apple Support

You're welcome.
