/*
* Sometimes the default password doesn't work, this is because people have moved the UB-04 card from one printer to another.
* when this happens, the printer retains the serial number from the old printer or sometimes the motherboard is replaced in
* the TM-L90. Either way the password wont work and you are not going to be able to config the network.
* This script starts at X2NJ00 0001 and works upto 9999. You might be able to start at 1000? but this should give you the serial
* number the printer wants as the default password.
* Hopefully this saves someones sanity.
