Hi

i want to enable a parrallel port LPT1 on Host Ubuntu 12.04, print ok from on linux but i don't enable it in the vbox using this command
VboxManage modifyvm 'server' --lptmod1 LPT1

i had this error

VBoxManage: error: Unknown option: --lptmod1

known why this error?

my version is 4.1.12_Ubuntur77245

Thank's for all

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).

Código Resultado: NS_ERROR_FAILURE (0x80004005)

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?

tank's all

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

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

when run from terminal say

• usuario@servidor1:~$ virtualbox

  usuario@servidor1:~$

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.

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).

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.

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

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

take same error

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


thank you so much for help
