How do I modify a printer's IP address in CUPS?

Question

I have a network printer with a static IP address. Recently I've changed my subnet and had to allocate it a new static IP address.

I've tried to update CUPS with the new IP address by going to Printers -> [Printer name] -> Administration -> Modify printer -> Current connection -> Continue. I'm presented with this screen but the connection string is not an editable box, so I can't change the IP address:

How can I modify the IP address?

I believe you can do it command line like in this answer: https://serverfault.com/a/36587/289128 — Terrance, May 09 '17 at 16:42

You can edit /etc/cups/printers.conf

In a terminal:
sudo systemctl stop cups

sudo vi /etc/cups/printers.conf - (or the text editor of your choice, I chose vi.)

locate the printer's URI (in bold below), it will be among all of your printers' profiles, they are arranged within tags like:

<Printer My Poop Laser Printer>
PrinterId 1
UUID urn:uuid:c41ca0c7-52f3-3448-5dfe-11281fc3ac2e
AuthInfoRequired none
Info
Location
MakeModel Generic IPP Everywhere Printer
DeviceURI ipp://192.168.200.2/printers/laser
State Idle
.
.
</Printer>

You can edit the IP there, save it.
And then restart cups...

sudo systemctl restart cups

I've never had much joy from the CUPS web interface.

You can change the printer URL here, at least if your setup is similar to mine.

Preferences/Printers, right click and choose Properties

Thanks. I'm using i3 on Xubuntu, so it isn't of much use for me, but might be useful for other users. What DE is that? Do you happen to know the name of the binary for that application? – Jon Bentley May 13 '17 at 21:58

I use Lubuntu, LXDE on Ubuntu, and stock Ubuntu; the printer dialog screen is the same for all. The name of the application is system-config-printer – Organic Marble May 13 '17 at 22:07

Great, I can confirm that I have that in Xubuntu (Xfce). – Jon Bentley May 13 '17 at 22:14
I've changed the accepted answer to this one as it more directly answers the question (modify the existing printer rather than delete/recreate a new one). – Jon Bentley Dec 19 '19 at 10:21

The IP address is not a modifiable field, because, if you changed it, it would describe a different printer.

Abandon the "Modify Printer" approach, and on http://localhost:631/admin, Find New Printer

This worked, but I also had to run my printer setup program after I "found" the "new printer". I have an HP printer, and in my case, I ran "hp-setup". – VectorVortec Jun 28 '17 at 04:09

I just went through the same exercise when my subnet changed. You can modify the connection. However, you will not be able to select current connection. You have to select a "new" connection, i.e., LPD or AppSocket or, for you, ipp. As your original/current connection is ipp, chose Internet protocol printing (ipp). Hit continue and fill out details the as current connection.

As root in a terminal window do, for example:

lpadmin -p HL2270DW -v http://192.168.1.102:631

Of course, substitute your own printer's name after -p. You don't have to do anything within the CUPS interface.
