[STR New]

Johannes, what I could do to improve that is making the after-job reset a
quirk option, currently only applying to the Prolific USB -> Parallel
adaptor.

The quirk behavior is hard-coded, it is the same as in the usblp kernel
module with some added quirk rules. For some quirk time there are also
admin-settable options:

- Forced uni-directional communication: "lpadmin -p <printer> -o 
  usb-unidir-default=true"

- Suppress re-attachment of the usblp kernel module after the job:
  "lpadmin -p <printer> -o usb-no-reattach-default=true"
