HashPrinter can be configured to print in two different ways:
Automatic - hashPrinter will print every image it finds that has your selected hashtag. You can toggle this setting under Printer Settings (make sure you're not in Full Screen mode - F11).
Manual - hashPrinter will only print images that are selected by your guests.
Before hashPrinter can print anything, it needs to know which printer you would like to use. To select a printer, press on Printer Settings, select your printer, and press PRINT to save your settings.
Currently, the generated prints are sized for printing on 4"x6" paper.
If the prints come out with the wrong orientation, change either or both your paper size and paper orientation under Printer Settings.
