List of Brother printers supported by PyKota : - HL3400C : - 'software()' - This printer supports both SNMP and PJL, but PyKota can't use either : hardware accounting fails because the internal page counter is not updated in real time. I may need to upgrade the firmware, or maybe using an external script to do hardware accounting is the solution. - HL2070N : - 'hardware(snmp)' : Worked so far with SNMP, but tested only for 1 week. I will correct the details if something is changing. PJL should work as well. - HL6050DN : - 'hardware(snmp)' - 'software()'
