lpadmin Issue need to be fixed

[chandrashekar]

Hi,

I am working on non-mac os, where in I dont have /dev/fd/ folders for file descriptors except for stdout, stdin, stderror.

I am trying to add printer with existing ppd from /share/cups/model folder. As soon as I enter lpadmin -p <printer> -v http://<ip>:631 -m Generic-PostScript.ppd. I am getting below issue

cups_model: empty print file.

I traversed through the code I saw cups-driverd is writting PPD to temporary output fd, which is taking 16 or 17 value in my pc. which my non-mac os is not recognizing. I have seen similar hurdle in case of foomatic-rip filter where in they are redirecting the output to /dev/fd/3 if not supported then they are directing to %stdout. Why cant cups server redirect the same to %stdout. I am pasting code snippet of schedular/ipp.c. Please let me know if i understood correct, is there any solution for this.

copy_model() Method:

if (!cupsdStartProcess(buffer, argv, envp, -1, temppipe[1], CGIPipes[1],
                         -1, -1, 0, DefaultProfile, NULL, &temppid))
  {
    close(tempfd);
    unlink(tempfile);

    return (-1);
  }
