When we 1st started in buissness we tried computers in the vans. We had some trouble. I think the biggest was cheep printers and humid or very cold weather. That really played havock on the printer. Since I started using inuit quick books on line and I've been emailing more bills. I would like to try having a computer in the van with the internet card and see if I could enter bills immediatly even if I have to write a hard copy that would be O.K. I just don't think a printer would work good for us in the trucks yet. maybe I'm wrong.
