I disconnected the usb cable and reconnected it and now they appear:

quadcore# lpq -a
lp:
Warning: no daemon present

quadcore# ls /dev/unlpt0
ls: /dev/unlpt0: No such file or directory
quadcore# ls /dev/ulpt0
ls: /dev/ulpt0: No such file or directory

reconnected it :

quadcore# ls /dev/ulpt0
/dev/ulpt0
quadcore# ls -l /dev/ulpt0
crw-r--r--  1 root  operator    0, 148 Jul 27 16:27 /dev/ulpt0


quadcore# ls -l /dev/unlpt0
crw-r--r--  1 root  operator    0, 149 Jul 27 16:27 /dev/unlpt0

I changed /etc/printcap, and two blank pages came out but blank :(

Thanks,

Antonio
