Since other applications show the same issue, and LibreOffice retrieves the
printers from CUPS, I'd be surprised if this was actually a LO problem and not
something on a lower level.

However, I'll be happy to test this further.
Can you give exact steps how to reproduce the issue? Can you reproduce this by
setting up a new local printer with a certain name and then delete it?

At a quick glance, LO uses 'cupsGetDests2' from the CUPS library to retrieve
available printers [1].

Can you run the attached sample program and paste the output here. It also uses
'cupsGetDests2' to retrieve and list printers (but might use different
parameters from what LO does, so the output may vary).

Also, do you have CPD (Common Printing dialog) libraries installed? (In this
case, LibreOffice uses those to retrieve printers instead.)
