Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
usb_printerid -V (return code: 1)
Error: No such file or directory: can't open '--version'
usb_printerid (return code: 1)
Error: usage: usb_printerid /dev/usb/lp0
