Print a picture from a modern PC with an old-fashioned Commodore MPS 803 compatible printer - this is a very cool use for all those CBM printers you have in your closet!  Basically you use a XUM1541 cable or a Zoom Floppy along with the OpenCBMTools to send .png pictures straight to your Commodore printer.  For more details and the latest version check out the github page - HERE
