Before that was something called "Tioga", and you will still find some vendors making Tioga printer drivers for Mac OS X which we still support up through 10.6 using a wrapper filter in CUPS.</div><div><br></div><div>The issue with target printing is that CoreGraphics always uses ColorSync and there is no simple API that allows an application to either a) specify the device color profile or b) get the device color profile in the print settings (job ticket) at print time.</div><div><br></div><div> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div>________________________________________________________________________<br>Michael Sweet, Senior Printing System Engineer, PWG Chair<br></div></span> </div> <br></body></html>
