<p class="MsoNormal">FWIW, CUPS previously supported two other attributes for scaling in the past - &quot;scaling&quot; (scale to a percentage of the media size) and &quot;natural-scaling&quot; (scale to a percentage of the document size). &nbsp;This allowed for &quot;poster&quot; printing over
 multiple media sheets, among other things, but had a lot of limitations and implementation issues. &nbsp;(BTW, we only ever supported symmetric scaling: scaling-width == scaling-height)<o:p></o:p></p>
