Custom paper wallet designs
The photoshop source files used to create the wallet art are located here. When you're ready, you'll want to export your wallet image as a BMP and then put it on Piper in the folder /home/pi/Printer/Images. You'll want to overwrite the existing image in that folder, making sure that the filename of your new image matches the old image so the Piper software can find your image file. You can post your wallet art on the Piper subreddit linked above, under "Community".
You can find the latest software update zip files here. To update Piper, you need a USB flash drive. Download the update and extract the zip file and you'll see a file named "Instructions.rtf" which contains instructions on how to perform the update.
SD card images
You can find the source code at the Piper Wallet github located here.
