<p class="MsoNormal">Michael and all,<o:p></o:p></p>
<p class="MsoNormal">I am not sure exactly when my membership in PWG lapses, but it may have done so already.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">That being said, I read with interest the specifications for thermal / Label devices. There is one attribute that I suggest you consider.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Labels come out of high-speed label printers in a direction that, when many labels are printed as a stream, appear to the operator to be printed backwards. Vendors provide a way to simply flip the labels 180 degrees and this “fixes” the
perception problem. In ZPL, that is ^POI. DPL and IPL have similar bits, but if these mime-types are not in play, perhaps an attribute at the IPP level might be considered.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Another common situation we see is “job interweaving”. Zebra devices are multi threaded, and can accept two or more jobs simultaneously. The problem is that there is no concept of a job. If I have two ZPL data streams coming at the same
time, labels from one stream may print between labels of the second stream. ZPL has no concept of a job, so anything between the initial ^XA and ^XZ which constitutes a single label is the only thing that is considered. I am not sure that this is fodder for
a specification, but it is a problem in many high-speed environment where labels are generated from multiple sources.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for taking time to read and consider this.<o:p></o:p></p>
