mobile laser printer

Hi all,

At present I'm using a Hp Officejet Mobile 100 in my Jeep in the field fro my work.  I egt tired of changing ink, not to mention the expense.  I want to install a small laser priner.  I purchased a Laserjet Pro 1102w and a Schumacher 1500 watt inverter.  Specs on the inverter says its 150 amps this thing is huge but it won't run the printer. Anyone know of an HP Laser that will run off that inverter or have any advice.  I do a lot of printing in the field and my mobile struggles to keep up.  Any help is appreciated.

Thanks in advance.
