[cups.general] need a debug/troubleshoot help [QNX 6.3]

[DoMinix]

hi there.

I have just compiled cups on QNX, including  espgs-7.07
everything went fine and is installed on /usr/local
cupsd run fine, got the web interface, created one or two device, OK
as soon as I try to print a test page I got a canceled job in the web
interface and a bunch things I'm not aware on the syslog.

I need advice to troubleshoot now,
I'm stuck with
    "Unable to convert file 0 to printable format for job 14!"
in the lo, how do I test if espgs work ?

thank for your time
