Okay, this looks typical except that you don't have the full networking part of the driver. 

It's recommended that you download and install the Solution:

Completely remove hplip and hplip-data (also completely removed hpijs, foomatic-db-hpijs and hpijs-ppds),
downloaded hplip-2.8.7.run from hplip.sourceforge.net and ran the automatic installer.

Note that there are 7 missing "optional" dependencies which it automatically downloaded & installed; two of these were marked as "REQUIRED dependency for option 'network'", so attend carefully as you install.

After building, a setup wizard runs which did almost everything by itself (but for some reason doesn't find the printer by itself -  you will have to enter its ip address manually), whereupon it will give you a choice of 2 drivers - choose the first one that is listed (not the one called 'recommended').

Printing to this printer now should to work perfectly.

Go into the CUPS "modify printer" process to see what is are now 2 new items listed in the "device" drop-down menu that were not there before:
HP Fax (HPLIP)
HP Printer (HPLIP)

Also, the device uri that the wizard entered is now:
hp:/net/Photosmart_C7200_series?ip=[my printer's ip address]
and the driver it is using isL
HP Photosmart c7200 series Foomatic/hpijs (en)
I was trying to use "HP PhotoSmart C7200 Foomatic/hpijs (recommended) (en)". Note that the slight differences in upper/lowercase are not accidental - compar';

Okay, so this is a printer shared through another computer, right?

Youubuntu can see the printer, but it says it's not plugged in.  What is the other computer?

Can you see logs from the other computer of access attempts.
What is it whining about?

That means basically it's "unplugged or turned off".  Check the cabling.

Here's whats happening: I have a printer connected to the desktop in my office. That prints fine.... all is good. I have a laptop that used to print to the printer but ever since the hard driv e crashed and I re-installed the OS it hasn't. I go to cups and go through the printer-discovery process (and it does find it). But it will not print.

# ps -ef }grep cups
# netstat -antp | grep 631
