Displays printouts directed to esc/pos standard mode printers. The printouts are shown on screen in a scrollable view and as scrollable list of thumbnails. Selecting a thumbnail shows the full printout. A thumbnail can be removed from the list helping management of printouts.
Every time a new printout arrives an alarm sounds, and an alarm icon is displayed.
This app can be especially useful in restaurant kitchens, bars, cafes etc. since no more paper orders are lost and the list of outstanding orders can be easily managed from the thumbnail list.
It’s also useful for programmers that can test their printouts without a printer.
