DocuPrint C525A on Fedora 11

[Pranas Baliuka]

Dear CUPS 1.4rc1 experts. I've tried using release on Fedora 11 x86_64 machine and stocked with problem:

...
D [23/Sep/2009:13:08:51 +1000] PID 2486 (/usr/lib/cups/backend/socket) exited with no errors.

After recompiling with gcc FXM_PF and replacing I am getting:
...
D [23/Sep/2009:16:30:45 +1000] [Job 18] printer-state=3(idle)
D [23/Sep/2009:16:30:45 +1000] [Job 18] printer-state-message="Ready to print."

E [23/Sep/2009:17:24:41 +1000] [Job 18] fxprefilter can not exec filter /usr/lib/cups/filter/FXM_MF.(errno = 2.)
...


Checking parameters of FXM_PF:
./FXM_PF
ERROR: fxprefilter job-id user title copies options [file]

Some ideas why fxprefilter can not invoke FXM_PF? I guess it is some cups.bug ...
Thanks!
