Eu preciso monitorar o estado da impressora HP (tinta, papel, etc.). O Hplip tem a ferramenta hp-info com modo debug e saída muito detalhada. Mas não consigo encontrar nenhuma documentação com explicação de seus dados. Por exemplo:
hp-info[31896]: debug: printer_status=1
hp-info[31896]: debug: device_status=2
hp-info[31896]: debug: cover_status=4
hp-info[31896]: debug: detected_error_state=64 (0x40)
hp-info[31896]: debug: Printer status=1000
There is no complete documentation for hp-info command. All that you can find is in hp-info - -help (or) man hp-info command. HPLIP is a open source project and you can find the complete source code of hplip @ http://hplipopensource.com/hplip-web/gethplip.html. You can explore through the source code to get more info on the data listed by hp-info command. Most of it is contained in codes.py & models.dat file of the source.
