I remember I had a similar problem with my USB->parallel adapter with my
printer. I think the solution was a udev rule to change the group
ownership to lp instead of root. You could try this command:
sudo chown root:lp /dev/ttyUSB0
Then try again if you can use the printer.
Please note: this isn't permanent, so if you unplug the serial converter
or if you reboot the problem will be here again. However, if that works I
would try to find out how to make / change the appropriate udev rule.
