I'm using https://github.com/hanazuki/docker-ubuntu-cups to run cups PDF on an ubuntu docker. I mapped like this:
sudo docker run -it -p 6310:631 -e ADMIN_USERNAME=admin -e CUPS_ADMIN_PASSWORD=admin -v $HOME/cups:/var/spool/cups-pdf/ANONYMOUS cups
so my 6130
port is 613
inside cups. I can access the web admin panel. However, I tried adding several printer types from this list:
Add Printer
Local Printers: CUPS-BRF (Virtual Braille BRF Printer)
CUPS-PDF (Virtual PDF Printer)
Discovered Network Printers:
Other Network Printers: Backend Error Handler
Internet Printing Protocol (https)
AppSocket/HP JetDirect
Internet Printing Protocol (ipps)
Internet Printing Protocol (ipp)
Internet Printing Protocol (http)
LPD/LPR Host or Printer
but none of them appears in my firefox (which is in the same machine) when I try to print something. I checked "share printer" in all of them.
How do I make a printer appear at firefox so I can print and get a PDF from it?
