| 10 | == CUPS management web pages == |
| 11 | |
| 12 | |
| 13 | The cups management pages should appear at http://<ip_address_of_indicator>:631 |
| 14 | |
| 15 | 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. |
| 16 | |
| 17 | Adding "/admin" to the url shows the administration page, but it is missing style information. |
| 18 | |
| 19 | 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. |
