We have seen the difficulties of having multitude of printer drivers in use today. If someone does not act now, the same is going to happen with cloud. Right now Google has a cloud proxy and it has its own protocol. Every other guy who enters this field is going to float his own protocol, proxy/client apps (like our drivers) and other specs. I feel PWG is the only forum which is in a position to do something to prevent this from happening. However, if PWG just stops at reviewing what is being used right now, it will not help us achieve the first aim. For this, it is essential that PWG makes some specification, even though it might be difficult to convince people like Google who are already in market. But, I feel PWG should give it a try and while doing that they should review the existing standards. However, this revision should be aimed at finding and specifying the lowest common denominator that can be extended in future with the cooperation of all the stake holders.<br>

<p class="MsoNormal"><span style="font-size: 14pt; color: rgb(31, 73, 125);">Although this is a great outline, it may give the impression that the PWG were intending to develop a Cloud Printing specification; from recent comments, it is not clear that we are or can. Indeed, there are already various Cloud Printing implementations deployed. I think that we are agreed that the PWG would like the basic printing semantics to be consistent with the PWG model, regardless of the implementation; this would not only provide a more consistent print capability for users, it would facilitate making the actual printers compatible with the various implementations. Hopefully, we could also encourage greater interoperability and thereby make more devices available to users (thereby increasing printer use).</span></p>
<p class="MsoNormal"><span style="font-size: 14pt; color: rgb(31, 73, 125);"> </span></p><p class="MsoNormal"><span style="font-size: 14pt; color: rgb(31, 73, 125);">We have already stated what we consider to be the basic characteristics of Cloud Printing. I think the next steps are to better understand the various implementations and consider, from the printer perspective, to what extent the semantics are or can be made consistent with the PWG model, and perhaps what must be added to the model. I would therefore cast this outline as a review of these aspects in extant or imminent Cloud Printing implementations rather than giving the impression that we intend to specify these things. Certainly, after we understand what has/is being done, we can consider from a printing viewpoint, to what extent they are compatible with the PWG model, what other solutions we might consider more compatible for interoperability, and indeed where our model may need to be improved.</span></p>
