thank you Perryg
Ok, Changing the version of VirtualBox and i can configured the LPT port but .....
put this "VBoxManage modifyvm "server" --lptmode1 "/dev/parport0",
"VBoxManage modifyc 'server' --lpt1 0x378 7"

and when run it say :

Parallel#0 could not claim parallel port '/dev/parport0'Be sure that no other process or driver accesses this port (VERR_DEV_IO_ERROR).

Parallel device 0 cannot attach to host driver (VERR_DEV_IO_ERROR).

This usually means you do not have permission to address the port. make sure you are a member of the lp group and lpadmin group on the host.

Note any changes to permission do not take effect until you have logged off and back o nor sometimes until a reboot.

Did you consider a network share for the printer?

[JulioRos]

tank's all

i adding my user call "usuario" to the group lp and lpadmin with "

Code: Select all

usermod -G lp usuario

" but i get the same error

Fallo al iniciar la máquina virtual server.

Parallel#0 could not open '/dev/lp0' (VERR_ACCESS_DENIED).

Parallel device 0 cannot attach to host driver (VERR_ACCESS_DENIED).

Julio

aditional info: i send "

Code: Select all

ls > /dev/lp0

" (like MS-DOS test port) and prints fine from the terminal , also login root and config the VM and take the same error ¿¿?? do you have any idea?

Did you consider a network share for the printer?

thank's for idea but i can't take the shared printer because the VM is a Novel Netware 4.2

Post the results of id from the terminal

[JulioRos]

when run from terminal say

• usuario@servidor1:~$ virtualbox

Let's try this again.
Open a terminal on the host and type id then press enter
Then post what that prints out on the screen.

[JulioRos]

as root say

Fallo al abrir una sesión para la máquina virtual servroot.

Parallel#0 could not get exclusive access for parallel port '/dev/lp0'Be sure that no other process or driver accesses this port (VERR_INVALID_PARAMETER).

[Perryg]

I can't help you if you do not do what I ask. I will await further assistance until you comply with my previous request.

[JulioRos]

this is a id

uid=1000(usuario) gid=1000(usuario) grupos=1000(usuario),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),109(lpadmin),124(sambashare)

thank's

[Perryg]

Add your user to the lp group and reboot. See if that lets you access the lpt port

[JulioRos]

take same error

usuario@servidor1:~$ egrep "lp" /etc/group
lp7:
lpadmin116:usuario
