Comment # 1 on bug 1232209 from Johannes Meixner

Leap 15 base system packages come from
SUSE Linux Enterprise Server (SLES) 15
and SLES 15 has CUPS 2.2.7.

To get a more recent CUPS version for Leap
you may use RPMs from the openSUSE Build Service (OBS)
development project "Printing", see the project info at
https://build.opensuse.org/project/show/Printing
which reads (excerpt):
--------------------------------------------------------
The "Printing" development project may contain
new software or work-in-progress changes of
existing software that might neither be in
a stable state nor fit well into currently
installed systems.

Have this in mind if you think about to install
packages from the "Printing" project into your
currently running system.

Do not use "Factory" if your system is not "Factory".
Use the matching packages for your particular system.

The packages in the "Printing" project are without
any guarantee or warranty and without any support.

As an extreme example, this means if your
complete computer center crashes because
of those packages, it is only your problem.

On the other hand this does not mean that those
packages are known to be terrible broken but
they are not thoroughly tested so that any
unexpected issue can happen.

In the end all software in the "Printing" project
are only applications which means that your system
should not "explode" when you upgrade with packages
from the "Printing" project (provided you use the
matching packages for your particular system).

If a new version does not work it should usually
help to downgrade (and to reconfigure as needed)
to get it working again.
--------------------------------------------------------

Currently the OBS development project "Printing"
provides CUPS 2.4.11 for Leap 15.6 which you may get
e.g. as RPM packages for the x86_64 architecure from
http://download.opensuse.org/repositories/Printing/15.6/x86_64/

Alternatively if you need in general recent software
versions, use openSUSE Tumbleweed, see
https://www.opensuse.org/

In particular openSUSE Tumbleweed currently
provides the same CUPS version 2.4.11
as in the OBS development project "Printing".

Regardless that the issue here is not invalid
I can only close this bug report as "invalid" because
"the problem described is not a bug", see
https://bugzilla.suse.com/page.cgi?id=status_resolution_matrix.html
because the CUPS version in Leap 15 is the one that is
intended for Leap in general - i.e. the one from SLES 15.
