8) When the printer prepares to print, it will activate the print head power and charge
a bulk capacitor attached to the print head. This current spike can be up to 15
amps for up to 200uS depending on the charge state of the capacitor.
9) Make sure the power supply specification includes any bezel current
requirements.
10) Consider that the frame ground and the 24V return are connected together in the
printer.
11) Use connectors in the power interconnect that are rated for the maximum average
current.
