Network Printing CUPS (Graphics Allowed)
825 Gen2 has CUPS (Common Unix Printing System). To enable cups use the "Setup Services" menu and select "CUPS Printing".
For web configuration and monitoring select "Yes" for "Web Access", "Main", "Admin", "Conf", and "Log". Press ENTER to save changes.
CUPS management web pages
The cups management pages should appear at http://<ip_address_of_indicator>:631
Check a Windows PC that is already configured to use the desired network printer.
This shows the IP address of the printer.
Click "Administration" on the 825 CUPS page.
Click "Add Printer."
Type the username and password. Click "Sign in".
Select the printer that looks correct in the list and click "Continue".
Make sure the IP address shown matches. The name and description may be changed if desired. Click "Continue".
Select the "Model:" "driverless" and click "Add Printer".
Click "Set Default Options."
The page should change to show "default options have been set successfully."
Select the maintenance drop down.
Select "Print Test Page."
This feature does not currently work. Will investigate further.

The PNG file did not print.

The cardinal_logo did print.
Maybe png files do not work, but bmp files do.

Technical information
From a terminal type /usr/sbin/lpinfo -v to show printers that are detected on the network in additional to local USB printers.

Many network printers support a protocol known as Bonjour. Bonjour is a combination of zero-configuration networking ("ZeroConf"), multicast DNS (mDNS), and DNS service discovery (DNS-SD) standards published by the Internet Engineering Task Force (IETF), the same group that defined TCP/IP and all of the networking we use today.
To just show only dnssd printers type /usr/sbin/lpinfo --include-schemes dnssd -v.

The line localhost:631 limits access so that the page could only be accessed from the 825 itself. Commented this out be placing # in front and added line Port 631 below it.
Added Allow @local just above each of the four </Location> lines.
Then restart the cups service
sudo systemctl restart cups
