CUPS does not recognize bluetooth receipt printer I've been given for testing purpose a mobile receipt printer and I am trying to set it up in cups. I've successfuly connected to it via `lubuntu blueman-manager` and printed test page via `cat testfile.txt > /dev/rfcomm0` and for the sake of some java application that will use it I need to set it up in cups. I get into cups web admin page, click `add printer` but the printer neither port are not found. Why? I've changed permissions under `/usr/lib/cups/backend/` and now I have situation from screenshot!!\[None printers available]1Now what?!

Does CUPS not have an option for "generic serial printer"?

Then point it to /dev/rfcomm0

Have you checked the rights on: /usr/lib/cups/backend/serial and /dev/rfcomm0

May only root accessible?

Found this on Arch Linux Forum: (Solved) Generic Serial Printer
