[Coco] usb printers on a coco

[Josh Harper]

 hi guys
I used to do lots of printing with my dmp-105 printers but due to the ribbons being unavailable these days the 105 is prett useless
most of my software the printed worked on the dmp-105 
what I need to know is there any  dmp out there that will work that the ribbons can be gotten for or better yet has anyone been able to get a usb printer to work on the coco 
maybe a new project 
usb printer adapter that emulates a dmp=105 to keep it compatable with all coco printing software
any ideas
thanks guys
