How we can print an image saved as base64 in our Rhoelement App using APD. Printer is a Zebra GX 420t.
Thanks in advance.
You can save your data uri (base64 string) to a file, like
File.open('your_image.png', 'wb') do |f|
Then use PrinterZebra Api's function PrintImageFromFile('your_image.png') to send it to your printer.
