The user has to be a member of the group lpadmin (something like
"Printer Administration" in the GUI [I don't have English locales])

No, you don't need to modify this. As the comment says this is the user
the server runs under.

Change it back to the default

What are the permission right now? It has to be writable for user cupsys

What's happening if you do something like (maybe use another file
instead  of passwd)
  cat /etc/passwd > /dev/lp0

Have a look at the logfile (/var/log/cups/error_log). Maybe change
LogLevel in /etc/cups/cupsd.conf to "debug" or even "debug2"
