Me neither :-)

Should work when adding a printer manually as well. Just the path where the 
grab the ppd from is different. And 'generic.ppd ' sounds like a very basic 
driver.

When you downloaded the ppd: 

> Deutsche Post recommends to use a driver for "Samsung SCX-6x55" from
> https://www.openprinting.org/ppd-o-matic.php?driver=Postscript-Samsung&print
> er=Samsung-SCX-6x55

you should be able to add the printer: 

docb@X1E:~> sudo lpadmin -p "Briefdruck" -P "/home/docb/Downloads/Samsung-
SCX-6x55-Postscript-Samsung.ppd" -v https://mailer-printer.epost.de/
kd5025991737/3025/test -E -o printer-is-shared=false -L "Deutsche Post AG"

Not sure that the Samsung driver is a good idea, as lpadmin reports back:

lpadmin: Druckertreiber sind veraltet und werden in einer zukünftigen Version 
von CUPS nicht mehr funktionieren.

[printer drivers are outdated and will not work in a future version of CUPS)

From here it needs a bit finetuning, test-print gives:
"Use "pdftops-renderer" option (see cups-filters README file) to use 
Ghostscript or MuPDF for the PDF -> PostScript conversion." 	
 
So maybe a very generic printer driver is a better choice

Hope that helps
Axel

PS: CUPS 2.4.2 on openSUSE Tumbleweed
