Heya, A fellow VCFer hooked me up with a ballin' thermal label printer. I was thinking... If someone could make an app that: 1. Consignment seller could plug in Item name, description, price - Could be done pre-event or on-site - Could be text based like a mainframe for that retro feel or webapp 2. Pile of thermal labels are printed with this info on site when attendee shows up. I think the 3" core direct thermal label rolls aren't terribly expensive - Could kick out a "seller" id card with a code as well for end tally Checkout: 1. Barcode read, item tally done, money tendered, etc 2. Maybe a dot matrix printer involved cause it sounds cool. Either for a receipt or sales transaction log. 3. Can print out end tally page Barcode readers act as keyboards usually with a tab or enter or whatever (configurable) so that part is easy. Could drive that side of it with a python/php/whatever script on a Pi. Text interface is probably easier. Thoughts?
