Overflowing dialog

STEPS TO REPRODUCE

Comment 1 Mike 2025-07-07 18:50:55 UTC 
I'm wondering which notification message you're seeing here?  When I attach the printer, the kcm appears automatically (no clicking needed) and defaults to the "Set up a printer..." dialog and the buttons/lists are sizing properly. 

Curious, if you open system settings, size it to it's minimum, then goto Printers and choose add..., what do you see?
Comment 2 Mike 2025-07-07 20:58:45 UTC 
Looks like with `kcmshell6 kcm_printer_manager --args --add-printer` it definitely overflows, however, when using the notification or running system settings directly, I get proper sizing of the controls, even when the system settings windows is resized (previously) to it's minimum.

Running kcmshell6 is clearly not working the same way as the system settings main window, meaning it will not save it's size when closed (it always defaults to quite small).

I guess the other question is are you scaling your display at all or just 100%?
Comment 3 Mike 2025-07-09 14:22:10 UTC 
I whipped up a branch (kind of rough) that ports the dialog to a kcm page, see if it solves it for you.  Drops some duplicate code and there's probably some tweaking to be done as well: https://invent.kde.org/plasma/print-manager/-/commits/work/noee/find-printer-page
