Hi, it is a usb local printer that is recognized by system but not found when I try to add it by running localhost:631>manage printers or >find new printer

I tried many ways and I noticed the print is recognized:

bash-4.3# /usr/lib/cups/backend/usb       
DEBUG: Loading USB quirks from "/usr/share/cups/usb".
DEBUG: Loaded 114 quirks.
DEBUG: list_devices

when I run the command below the return is :

bash-4.3#  lpinfo -v
network socket
network ipps
network https
network lpd
network ipp
network http
bash-4.3#

I have downloaded the driver and installed it. it was useless...

tks in advance for those who print and maybe have an idea.
