KDE Live 64bit

skanlite does not detect Canon printer which is installed and printing.

Installed simple-scan and get following error:

Code: Select all

one[~]$ simple-scan

** (simple-scan:3934): WARNING **: Unable to get open device: Invalid argument
process 3934: arguments to dbus_message_iter_append_basic() were incorrect, assertion "_dbus_check_is_valid_utf8 (*string_p)" failed in file dbus-message.c line 2749.
This is normally a bug in some application using the D-Bus library.
  D-Bus not built with -rdynamic so unable to print a backtrace
Aborted

Cannot open scanlite or simple-scan as sudo to check if in that mode it would find the printer.

Which would be the device /dev/ for the printer to give as an option with flag -d?

I do not know. If it is a usb printer look on /dev/usb/ to see what ports are there. Or see dmesg output ( sudo dmesg | tail) for errors.

It is a usb connected printer. Tried some /dev/* and nothing doing. dmesg does not tell anything and does not change output.

sudo simple-scan or sudo skanlite gives me:

Code: Select all

sudo skanlite
No protocol specified
skanlite: cannot connect to X server :0
[/code/
How can I then open as sudo?

If I start simple-scan as root-dolphin printer still not found and output of dmesg is:
[code]

Add user one to lp group. Log out and log in again. Then run simple-scan as user.
