We know you've got questions, and if you're brave enough to ask the world for answers, then here's the outlet to do so. This week's Ask Engadget inquiry is from Ryan, who needs a device that'll save him time out on the job. If you're looking to ask one of your own, drop us a line at ask [at] engadget [dawt] com.
"Hi. I'm an electrician that travels around in a van all day. Right now, I can either write receipts by hand or email to my customers after the fact. Is there any printer that I can use in the van and print from a phone or tablet? I only need to print out black and white on standard 8.5-inch by 11-inch paper, but nothing online seems to be what I need. Any help you can provide would be great, thanks!"
Well Ryan, we always feel a bit icky recommending printers, since we all know that they are the devil's work, but you've got a specific need, so we shall do our best. Assuming you can grab a power inverter and therefore use any consumer-level printer that runs WiFi Direct or AirPrint (if you have an iOS device). Some examples include Brother's HL5470DW or the HP 1102W. Beyond that? Well it's time to turn this shebang over to our commenters, who will be happy to share some knowledge.
