A recent issue on the Javascript IPP project (<a href="https://protect-us.mimecast.com/s/QAYgC82A5Ah69A6zBI233N3?domain=github.com" class="">https://github.com/williamkapke/ipp/issues/72</a>) highlights an issue with the "page-ranges (1setOf rangeOfInteger)" Job Template attribute, namely that a Client cannot discover how many ranges a printer supports. The existing "page-ranges-supported (boolean)" attribute only specifies whether the "page-ranges" Job Template attribute is supported and not the maximum number of values a Printer supports. Moreover, existing Printers seem to ignore extra values without reporting this in the unsupported attributes group of the Create-Job/Print-Job/Print-URI/Validate-Job response, so from the perspective of the Client nothing has gone wrong.<br class="">
<br class="">
For other attributes we have a "max-xxx" Printer Description attribute that tells the Client how many values can be specified, e.g., "max-stitching-locations-supported" and "max-materials-col-supported". I therefore propose to register a new "max-page-ranges-supported (integer(1:MAX))" Printer Description attribute that a Printer can return to specify the number of page ranges the Printer supports.<br class="">
<br class="">
Here is the registration template:<br class="">
