Comment:
Thanks for your bug report.
gnome-cups-manager indicates the wrong printer model and driver because it looks under Manufacturer "HP" while hpijs drivers are listed under "HP (HPLIP)".
According to the Adobe PPD specification v4.3 the manufacturer indication for Hewlett Packard should be "HP" and gnome-cups-manager is following this specification. The problem is in PPDs of package hplip-ppds, here "HP (HPLIP)" is used as *Manufacturer indication. I have filled a bug report in Debian for this a while ago that can be found here: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=347264.
Feel free to add comments to it to get the problem solved as soon as possible.

Please note that it is only the model and driver indication in gnome-
cups-manager that is wrong. Printing works without any problems and the
right printer model and hpijs driver are effectively used for printing
as found inside the PPD set up for your printer in /etc/cups/ppd.

I also have this problem with my HP DeskJet 3820 printer when choosing
"Local Printer" in step 3, so it is not related to network printers.

In your case the DeskJet 612C with it's recommended driver cdj550 are
matched under "HP" because it shares the first 3 digits of the model
number with your DeskJet 6127 printer (closest match).

A simple fix is to replace "HP (HPLIP)" by "HP" for PPDs inside /usr/share/ppd/hplip from hplip-ppds package with following command in a terminal:
$ sudo sed -i 's/HP (HPLIP)/HP/' /usr/share/ppd/hplip/*

If you run gnome-cups-manager again after this fix you will see the
correct printer model and driver indication under Properties!
