I am confused here.

The listings for both the HP and the Epson printers (which cannot be around at 
the same time! is coming from cups. If I attempt to probe the lp0: printer 
from hplip, it will not detect it. The very old version of hplip (from stable) 
did detect it and enabled me to try the functions (that the printer does not, 
in fact use).

Both printers are installed via cups. I switch the lp0: between them.

The URIs were assigned by the cups setup. I manually edited the 
/etc/cups/printers.conf and changed the parallel: prefix to hp:. This did not 
help hplip and the printers no longer worked. There are no underscores, just 
parralel:/dev/lp0.

Since the older (stable) version worked, I filed this bug. The suggestion was 
not mine but an earlier poster who found a similar problem.
