Creates device URIs for local and network connected printers for use with CUPS.

Usage: hp-makeuri [OPTIONS] [SERIAL NO.|USB ID|IP|DEVNODE]

[SERIAL NO.|USB ID|IP|DEVNODE]
  USB IDs (usb        "xxx:yyy" where xxx is the USB bus ID and yyy is the 
  only):              USB device ID. The ':' and all leading zeroes must be
                      present.                                             
                      (Use the 'lsusb' command to obtain this information. 
                      See Note 1.)                                         
  IPs (network        IPv4 address "a.b.c.d" or "hostname"                 
  only):                                                                   
  DEVNODE (parallel   "/dev/parportX", X=0,1,2,...                         
  only):                                                                   
  SERIAL NO. (usb     "serial no."                                         
  and parallel                                                             
  only):

  Show the HP Fax     -f or --fax                                          
  URI only (quiet                                                          
  mode):                                                                   
  Set the logging     -l<level> or --logging=<level>                       
  level:                                                                   
                      <level>: none, info*, error, warn, debug (*default)

  number):                                                                 

Notes:
1. Example using 'lsusb' to obtain USB bus ID and USB device ID (example only, the values you obtain will differ) :
    $ lsusb
    Bus 003 Device 011: ID 03f0:c202 Hewlett-Packard
    $ hp-makeuri 003:011
    (Note: You may have to run 'lsusb' from /sbin or another location. Use '$ locate lsusb' to determine this.)

CUPS URI: hp:/net/HP_LaserJet_4000_Series?ip=10.180.156.245

Done.

Copio la CUPS URI e faccio una query per vedere se la stampante che mi risponde e' quella che voglio io:

root@baix:~# hp-query  -dhp:/net/HP_LaserJet_4000_Series?ip=10.180.156.245 

warning: hp-query should not be run as root/superuser.
hp-query: error: Must specify key with -k/--key or specify -a/--all.
 

Vuole una chiave e gli specifico il parametro -a (all):

root@baix:~# hp-query  -dhp:/net/HP_LaserJet_4000_Series?ip=10.180.156.245 -a
