Tropy allows you to print out your items and their metadata using a standard print dialog box.
To print, select the item or items you wish to print. (To select multiple items, press Ctrl + click each item you wish to select.) Then navigate to File > Print. You can also press Ctrl+P to see the print dialog box. The print dialog box gives you many options for formatting and layout. Select the format you want and click Print.
Tropy's preferences give you options for what parts of your items you wish to print. To change these preferences, go to Preferences and scroll down to Print. In that panel you can select whether to print with notes, with metadata, and with photos.
