Parallel Printer cant configured

[Perryg]

Not sure what you mean. I see the group listed and I see you are not in it. What exactly is the question?

[JulioRos]

Sory, i cut and paste anything.
i create another machine with ubuntu 12.04 and virtualbox 4.2.12 r64980 and get the same error.

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

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

[Perryg]

And again what groups are you a member of?

[JulioRos]

yes this is a group members(my user is 'usuario')

Code: Select all

adm:x:4:usuario
tty:x:5:
disk:x:6:
lp:x:7:usuario
mail:x:8:

and change permission of lp0 chmod -c 777 /dev/lp0

and geting same error, i don't understand, post this in a linux forums

Hi, sorry to revive this old thread but I don't see it solved and I am having the same problem (I believe is the same).
My goal is to use an old scanner that only has parallel port. The only driver I was able to find so far is for Windows XP and the only computer I have with parallel port has to stay the way it is now (linux). I am running VirtualBox 4.3.32 under Gentoo Linux Distribution.

So far I haven't even connected the scanner since I am first dealing with forwarding the parallel port to the Windows XP virtual machine

My user is member of the lp and lpadmin groups:

tatoringo@garza-server ~ $ id
uid=1000(tatoringo) gid=1000(tatoringo) groups=1000(tatoringo),7(lp),10(wheel),1
8(audio),19(cdrom),27(video),80(cdrw),85(usb),100(users),104(vboxusers),105(scan
ner),106(lpadmin),250(portage),1001(plugdev)

I checked the Kernel and believe I have all set although I don't get a /dev/parport* but I do get a lp0, and that is the one I am trying to use by:

VBoxManage modifyvm "XP V machine" --lptmode1 "/dev/lp0"
VBoxManage modifyvm "XP V machine" --lpt1 0x378 7

right now I am getting:

Failed to open a session for the virtual machine XP V machine.
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).
Parallel device 0 cannot attach to host driver (VERR_INVALID_PARAMETER).
