I have not tried yet fw received from you because I removed the printer from the network and I connected it via USB to a PC in another location. When I manage to do tests with fw that you kindly sent me, I will post the results here.
Hello @ZeroHour,
unfortunately I met myself a printer HP Laserjet P2055dn which has problems with networking, so, please be kind and send me the firmware that solves the problem to me.
Thank you very much
