I want to print using CUPS while keeping SELinux enabled. (Linux)

  1. Backup the "/etc/selinux/targeted/contexts/files/file_contexts" file before making any changes to the original file.
  2. Check "/usr/local/Brother/" folder to find what folders are under it.
    1. If your system has "inf", "lpd","cupswrapper" folders under "/usr/local/Brother", add the following 3 lines to the end of the file ( /etc/selinux/targeted/contexts/files/file_contexts ).

      /usr/local/Brother/inf/.* -- system_u:object_r:cupsd_etc_t:s0
      /usr/local/Brother/lpd/.* -- system_u:object_r:bin_t:s0
      /usr/local/Brother/cupswrapper/.* -- system_u:object_r:bin_t:s0
       
    2. If your system has "inf", "lpd","cupswrapper" folders under "/usr/local/Brother/Printer/[your printer's name]/", add the following 3 lines to the end of the file ( /etc/selinux/targeted/contexts/files/file_contexts ).

      /usr/local/Brother/Printer/(printer name)/inf/.* -- system_u:object_r:cupsd_etc_t:s0
      /usr/local/Brother/Printer/(printer name)/lpd/.* -- system_u:object_r:bin_t:s0
      /usr/local/Brother/Printer/(printer name)/cupswrapper/.* -- system_u:object_r:bin_t:s0

    The part after the doble hyphen can differ between distributions. Refer the followings to confirm the correct statement for your distribution.
     

    • For "lpd" and "cupswrapper", the part should be the same as the configuration for "/usr/lib(64)/cups/deamon/.*" in the "file_contexts".
    • For "inf", the part should be the same as the configuration for "/etc/cups/ppd/.*" in the "file_contexts".
  4. Run the command "restorecon *" in the following directories:
    (For step 3-a.)
    /usr/lib/cups/filter
    /usr/lib64/cups/filter <===This is necessary only for 64bit OS users
    /usr/local/Brother/lpd
    /usr/local/Brother/inf
    /usr/local/Brother/cupswrapper

    (For step 3-b.)
    /usr/lib/cups/filter
    /usr/lib64/cups/filter <===This is necessary only for 64bit OS users
    /usr/local/Brother/Printer/(printer name)/inf
    /usr/local/Brother/Printer/(printer name)/lpd
    /usr/local/Brother/Printer/(printer name)/cupswrapper
     
  5. Restart the PC.
