Bug ID: 521508
Summary: "Printer/Device Admin Page" points to wrong URI for
IPP devices
Classification: Applications
Product: systemsettings
Version First 6.6.4
Reported In:
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: kcm_printer_manager

Target Milestone: ---
DESCRIPTION
when running an IPP server on e.g. localhost, connected to cupsd,
the kde printer settings dialog shows:
"CUPS Printer Overview Help" -> http://localhost:631/help/overview.html
"Printer/Device Admin Page" -> "http://brother_td_2020_usb";
despite the actual printer admin beeing:
http://127.0.0.1:8142/Brother_TD-2020_(USB)
the IPP server is exposing the information correctly via:
printer-more-info (uri) = http://127.0.0.1:8142/Brother_TD-2020_(USB)/
printer-uri-supported (uri) =
ipp://127.0.0.1:8142/ipp/print/Brother_TD-2020_(USB)
and CUPS reports:
printer-more-info (uri) = http://localhost:631/printers/Brother_TD_2020_USB
printer-uri-supported (uri) = ipp://localhost:631/printers/Brother_TD_2020_USB
device-uri (uri) = implicitclass://Brother_TD_2020_USB/
so from my point of view, the issue is in ui/PrinterSettings.qml:90
```qml
const url = new URL(devUri.text)
```
for IPP printers it should use "printer-more-info" instead of `device-uri`
STEPS TO REPRODUCE
1. run a PAPPL(https://www.msweet.org/pappl/) app (e.g.
https://github.com/arminfelder/br-thermal-printer-app)
2. add a printer to the PAPPL app
3. go to KDE printer settings dialog, and check the printers Device Admin Uri
OBSERVED RESULT
device-uri is used instead of the actual admin webpage of the IPP printer
EXPECTED RESULT
"Printer/Device Admin Page" points to the endpoint defined in
printer-more-info
SOFTWARE/OS VERSIONS
Operating System (available in the Info Center app, or by running `kinfo` in a
terminal window):
KDE Plasma Version: 6.6.4
KDE Frameworks Version: 6.24.0
Qt Version: 6.10.2
ADDITIONAL INFORMATION
```
printer-more-info (uri)
This RECOMMENDED Printer attribute contains a URI used to obtain more
information about this specific Printer. For example, this could be
an HTTP URI referencing an HTML page accessible to a web browser.
The information obtained from this URI is intended for End User
consumption. Features outside the scope of IPP can be accessed from
this URI. The information is intended to be specific to this Printer
instance and site-specific services, e.g., Job pricing, services
offered, and End User assistance. The device manufacturer can
initially populate this attribute.
