[cups.general] lpadmin Issue need to be fixed

[Michael Sweet]

What version of CUPS?

What OS/Linux Distribution?

Does "lpinfo -m" list "Generic-PostScript.ppd"?

Do you see any other errors, particularly from cups-driverd, in the error_log file?

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.
