Nothing is printed for any pages identified that do not exist in the Set/Document(s). Ranges MUST be in ascending order (1-3, 5-7, 15-19, etc.) and MUST NOT overlap so that a non-spooling Printer can process the Job in a single pass. If the ranges are not ascending or are overlapping, the Printer MUST reject the request and return the 'client-error-bad-request' status-code. The example in lp(1) is correct. The wisdom of justifying the entry by reference to an RFC is questionable. However, upstream listens and generally responds: https://github.com/apple/cups/issues Regards, Brian.
