parport0 error using my HP printer
 

Hi all,
i'm using Slackware 9.1 and i wanna try to use my HPOfficeJet G85 using parallel port.
My linux box is used also as samba server so i would like to print from any MS client
using the box as print server.
I recompile the kernel 2.6.6 and attach to parralel print port my HP.
At startup i see:
kernel: parport0: PC-style at 0x378 (0x778) [PCSPP,TRISTATE,EPP]
kernel: parport0: irq 7 detected
kernel: parport0: Printer, Hewlett-Packard OfficeJet G85

So i think it's all right. Then i install LPRNG software and create a queue.
When i check if it's all right after editing printcap file using checkpc -f command, it
gives to me that response:
Warning - HPDeskjet: cannot open lp device '/dev/parport0' - Permission denied

if i change permissione that respose:
Warning - HPDeskjet: cannot open lp device '/dev/parport0' - No such device or address

So when i try to print using a WindowsClient i obtein the same above result:

opening device '/dev/parport0' at 2004-05-13-19:11:32.335 ## A=nobody@nettuno+188 number=188 process=228
cannot open '/dev/parport0' - 'Permission denied', attempt 1, sleeping 10 at 2004-05-13-19:11:32.336 #

or with right permission:
opening device '/dev/parport0' at 2004-05-13-19:22:42.358 ## A=nobody@nettuno+443 number=443 process=468
cannot open '/dev/parport0' - 'No such device or address', attempt 1, sleeping 10 at 2004-05-13-19:22:42.359

I'm going mad =/ please any good advice will be very appreciated
Thanks a lot

Try (as root)
echo "hello" > /dev/lp0

root@nettuno:/# echo 'hello' > /dev/lp0
-bash: /dev/lp0: No such device or address

Very interesting. Try
mknod -m 666 /dev/lp0 c 6 0

root@nettuno:/# mknod -m 666 /dev/lp0 c 6 0
mknod: `/dev/lp0': File exists

the same thing if i use parport0 =/

Thank you very much fot your interesting about my problem, i don't know what else try. HEre i paste what kernel said at startup:

nettuno kernel: parport0: PC-style at 0x378 (0x778) [PCSPP,TRISTATE,EPP]
nettuno kernel: parport0: irq 7 detected
nettuno kernel: parport0: Printer, Hewlett-Packard OfficeJet G85
