I just bought an GWP-80 portable thermal printer and I was trying to make it works in Ubuntu 14.04 OS (in Windows works perfectly)
when I plug it into usb the system recognize an unknown printer then I tried to install through the wizard a generic text only driver but it didn't worked.
So I tried to run lsusb comand here is the output for the printer
Seems that the printer even if it ONLY HAS A USB plug, has an embedded usb-to-parallel chip installed.
Bus 003 Device 004: ID 067b:2305 Prolific Technology, Inc. PL2305 Parallel Port
then I checked and /dev/usb/lp1 device is present on my system
Anyone has an Idea about how to make this small printer works in UBUNTU ?
