When adding a printer a list of discovered printers is shown. If there are duplicate entries, for example if the same network printer is discovered with different network protocols (LPD, IPP, ...), these entries are usually grouped into one by using the D-Bus service of system-config-printer. system-config-printer groups entries coming from the network connection of the printer and groups entries coming from the USB connection of the printer, but it does not group network results with USB results, as system-config-printer separates them by a tree view. This means that when one connects one printer by both network and USB one gets two entries, one generated from all appearances under the discovered network printers and one from all appearances under the discovered USB printers (and if theis printer does Bluetooth there would be a third entry). Now the g-c-c printer tool lists these entries as
<model name>
<model name>-2
This way the user does not know which is the network printer and which is the USB printer. The results dhould look like
<model name> (USB)
<model name> (Network)
To reproduce connect a printer with both network and USB (or Bluetooth) input by both network and USB, then try to set it up with the preferred connection type.
This is a regression compared to Quantal. There system-
