IMHO you should point out that weakening encryption server-side is
nothing but a workaround, valid until the problem has been solved at its
root: The barcode scanners need to be upgraded.
If you rely on trusted CA certs instead of self-signing them, you might
be out of luck when the current certs need to be extended: *None* of the
OS's trusted root CAs will issue any SHA-1 certificate any more as of
this year. Doublecheck if the scanners can operate on a currently issued
cert. Alternatively you will need to roll out your own CA with - more or
less - self-signed certificates. Any one of these solutions will do, but
they might bite you if they come unsuspected and at an inconvenient time.

well... at least you can mention it - make an impression by pointing to
an insecure requirement that has been made under the assumption of
adding security.

I've mentioned "Apache httpd (or equivalent webserver of your choice)".
In this case IIS seems to be the webserver of your choice.
