Clicking the "Additional Printer Settings…" button launches system-config-printer multiple times

It looks like it's 7 instances every time.

Status changed to 'Confirmed' because the bug affects multiple users.

that's not important enough to be a milestoned -> rls-bb-notfixing

still worth looking at/fixing though, Till can you have a look?

sorry we changed our minds, this should be worked on please

For me it looks like a bug in gnome-control-center.

When clicking the button, it should be checked whether there is already a system-config-printer process running. If so, the window of it should be pulled to the front, if not, s-c-p should get started.

In addition, it must be made sure that the button action happens only once when one clicks the button once, and not repeatedly as long as the button is held down. The reports of some users that they get 7 instances of s-c-p with a single click on the button looks like that in the few milliseconds while they have the left mouse button down the action of starting s-c-p is repeated in quick frequence.

So these issues need to get fixed in g-c-c.

Till, is there any good reason a user would need to have multiple system-config-printer windows open. If not, I think you should leave the system-config-printer task open because the app should be converted to single-instance.

This bug was fixed in the package gnome-control-center - 1:3.28.0-0ubuntu4

---------------
gnome-control-center (1:3.28.0-0ubuntu4) bionic; urgency=medium

  * debian/patches/ubuntu-printer-support.patch
    - Connect to the system-config-printer-button{1,2} clicked signals
      during init rather than in update_sensitivity. This prevents us
      from connecting to the signal multiple times. (LP: #1755514)
