<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Based on existing implementations there appears to be some confusion around the use of the ‘custom_min’ and ‘custom_max’ name prefixes.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">There are two attributes that are associated with selecting the size of media. The first is “media” which is a type 3 keyword or name. The associated “media-size-supported” is a set of type 3 keywords or names. To specify a printer that
supports only specific media sizes within a given range, “media-supported” would contain the allowed values. The list can contain standard as well as custom names. To specify a printer supports any media within a given range the “custom_min” and “custom_max”
media values are used. As long as the media supplied by the client is within the range, the job is accepted.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The other attribute for specifying media size is “media-size” which is member attribute of “media-col” collection. The associated “media-col-supported” is a set of “media-col”. The "media-size-supported" is sort of a database of supported
media and each unique combination is explicitly enumerated. For this reason the “media-col-supported’ is specially handled when getting the printer’s attributes. To specify two different supported sizes and example would be {{x-dimension:210, y-dimension:297},{x-dimension:297,
y-dimension:420}} to show that it supports two values of "mediasize": A4 (210x297) and A3 (297x420). It does not support other combinations of "x-dimension" and "y-dimension" member attributes, such as 210x420 or 297x297, and it does not support non-enumerated
values, such as 420x595.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The mistake that has been seen in implementation in the field is that when a supported size range is specified, not all the media sizes within that range are actually supported.<o:p></o:p></p>
