HP Proprietary plugin require message showing..
 

Hi all, My OS is CENTOS 6.5 and i am trying to access a HP printer through CUPS in my lan...i have installed hp-plugin 3.12 version...but when i try to print a test page it ask for propietary binary plugin requires message. However I can print from the same printer using windows machine.My printer is HP 1108 usb printer and it is connected to our cups server.
By the way, the installed printer automatically appears in my printing menu and i can print with no problem if i am on same lan.But if i try to add the printer manually..it adds successfully,but not able to print.My problem is i am moving behind squid proxy network and when i change my network,i am unable to view the printer that appears automatically.So i need to install the printer manually, so if my proprietary plugin problem resolve, i can shift my current network behind the proxy.Please guide.

The required proprietary firmware is usually installed automatically when installing using 'hp-setup', but it can be done as a separate step using the 'hp-plugin' utility.

Hope that helps.

was the printer pluged in when you installed centos6 ?
if so all the needed hp/hplip software should have been auto installed
( the "HP control center" might be an exception to that)

the best way to set up the printer is using the CUPS web interface
http://localhost:631/
the link above is for your system

just set up the printer
fallow the on screen instructions

Thank you guys for your answers....I can print directly if i connect the printer usb in my Linux desktop,it wont ask for any plugin...but when i manually try to add the printer (by ipp or https) i face the plugin requiremnet problem.By using windows machine i can successfully print from cups server.I have opened all the required ports ie 631,161,162,9100 (both tcp and udp),but till now no luck :(

Strange.... maybe consider reporting the behaviour
