I already thought about using PrintServiceLookup. I could use it to show
the user the currently available printers, but I can't use it to create
a javafx.print.Printer instance without reflective access (JPMS).
At the moment I'm stuck with a an unmodifiable OberservableSet that
never updates.

Hi,
I use it through the javax.print API:
ObservableList<PrintService> printServices =
FXCollections.observableArrayList(
PrintServiceLookup.lookupPrintServices(null, null));
Maybe it may help for now, but to me it seems it should not be static.

Is there some way to update the ObservableSet of Printers once the

the same OberservableSet and it does not change - ever. [1]
We have an JavaFx based application running under Windows 10/11
that is
used to print on wireless printers, that are not always available.
Having to restart the the application every time a printer goes
away or
comes available is a serious pain for the users.
Is there any kind of workaround?
I doubt it will be fixed in the near future, since this comment is
