cups 1.2 - no output

[Rainer Heesen]

the permissions of /dev/ulp* are:

crw-rw----  1 root  cups        0, 169 Jul  3 20:35 /dev/ulpt0
crw-rw----  1 root  cups        0, 170 Jul  3 20:35 /dev/unlpt0

the directory /var/cache/cups is group writable

when I start a print job I get the message 

printer Minolta now printing Minolta-59.  enabled since Mon Jul  3 20:53:42 
2006
        USB port busy; will retry in 30 seconds...
Minolta-59              guest            18432   Mon Jul  3 20:53:42 2006

however, there is now output of fstat | grep ulpt0

'fstat |grep cups' gives this output
