Previously, I had sorted out my home printer to use a RaspberryPI as a print server and so offer shared printing services on my home wi-fi. However, my printer is a Canon MP630 which is a printer and scanner.<\/p>\n

I have a need to scan some old photographs but do not want to mess around disconnecting the MP630 from the RPi and reconnecting it to my main computer. I need to turn my RPi into a network printer and scanner controller that can be built as an embedded system using Buildroot.\u00a0 With this as my main requirement, I ‘googled’ ‘network scanner linux’<\/em> software and in the search result was the name ‘saned<\/em>‘ .<\/p>\n

A bit of investigation followed; could sane<\/em> be easily configured in Buildroot? what supporting files did I need to create?. There is a ‘sane-backends’<\/em> directory in the Buildroot ‘package’ directory, so after 30 minutes or so of reading I decided to give it a try. The steps needed were:<\/p>\n

    \n
  1. enable ‘sane-backends<\/em>‘ in the root system configuration to be used by Buildroot to create the root file system<\/li>\n
  2. create an overlay file saned.conf<\/em> which determines who can access the network scanner<\/li>\n
  3. create a startup file in \/etc\/init.d<\/em> called S91scanner<\/em> which starts\/stops\/restarts the sane network daemon to automatically start the network daemon at startup.<\/li>\n
  4. define the sane network port in a \/etc\/services<\/em> overlay file<\/li>\n
  5. then tell Buildroot to build me a new root file system.<\/li>\n
  6. move the image to a micro-SD card and boot the RPi<\/li>\n
  7. On any client system install something like xsane which is a scanner front end.<\/li>\n<\/ol>\n

    Amazing, I was able to scan photographs in remotely on the scanner, and then print them from the remote printer\/scanner using the RaspberryPi 0W as the print & scan server.<\/p>\n","protected":false},"excerpt":{"rendered":"
