+== CUPS management web pages ==
+
+
+The cups management pages should appear at http://<ip_address_of_indicator>:631
+
+It is showing "Not found" but it is shows "CUPS v2.4.2" so it seems the cups web server is running but some page information is missing. 
+
+Adding "/admin" to the url shows the administration page, but it is missing style information.
+
+After some research it seems the Yocto recipe "cups-doc" is needed to provide the static page information such as index.html and cups.css. This was added in the 825 image build 2024-01-16. This fixed the problem.
+
+[[Image(cups_mainpage.png)]]
+
+
+Check a Windows PC that is already configured to use the desired network printer.
+
+[[Image(windows_printer_properties.png)]]
+
+This shows the IP address of the printer.
+
+Click "Administration" on the 825 CUPS page.

+
+Click "Add Printer."

+
+Select the printer that looks correct in the list and click "Continue".
+
+[[Image(cups_add_printer_name.png)]]
+
+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".
+
+[[Image(cups_set_printer_options.png)]]
+
+Click "Set Default Options."
+
+[[Image(cups_set_default_options_success.png)]]
+
+The page should change to show "default options have been set successfully."
+
+[[Image(cups_printer_info.png)]]
+
+Select the maintenance drop down.
+
+[[Image(cups_maintenance_dropdown.png)]]
+
+Select "Print Test Page."
+
+[[Image(cups_unable_to_print_test_page.png)]]
+
+This feature does not currently work. Will investigate further.
+
+Maybe printer test page is also part of cups-doc recipe.
