Not sure I can help, but I throw in a couple of thoughts ...
    How did you configure the printer to begin with?
       through some GUI configuration tool?
       through the command line interface (cli)?
       just let CUPS find it and then try to use it?
       or something else?
    I used to always use cli, but I have been using GUI for years now, 
and I find (at least on my systems), that
       the newer HP printers and all-in-ones do really well under the HP 
Device Manager, using "HP jet Direct" as a connection type
       the older HP printers do better without the HP Device Manager, 
using "TCP/IP Host IP" as a connection type
          in either case, I configure them as "network" printers ... but 
then they are network printers, each with their own IP and Ethernet cable.
    I used to put the printer IP's in the /etc/hosts file, and use the 
name assigned there when configuring the printer ... now i just put the 
IP in the printer configuration.
       of course, if I had to configure a lot of printers again, I'd 
probably go back to using the /etc/hosts file again.
Does any of the help?
