If you do parallel:, CUPS will issue ioctls that usblp cannot support (actually hardware does not support).

You can verify that by printing longer files with unix2dos|cat. -- Pete -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
