We are using StaticReceiptPrintJob to print receipts and we add the signature as an image file using footerUris(). This was working months ago and at some point it stopped working in production. Our URI is similar to file:///storage/emulated/0/saved_images/filename.jpg. I have verified the file contains the image needed to be displayed, but it does not get printed on the receipt.
Any/all insights as to why the image is no longer printing are appreciated.
