OK, here's the situation. I'm working on a thin-client app, so the user only has IE. The app renders large images (think 1000x2000 pixels), sometimes rotated. We are NOT using HTAs.
To print, we pop up a new HTML document with just the image, and send that off to the printer.
Now, as I mentioned above, the some pages may be rotated. It's these I'm having trouble printing-- the aspect ratio keeps getting screwed.
I don't know the size of the paper, so I can't scale against that. The document sent to the printer seems to be scaled according initial window, not the target media.
Here's a concrete example. Let's say I have an image that's 2000 pixels wide and 1000 pixels tall. Now, when I prepare my to-be-printed document, I have to scale the width of the image to fit the document-- 100% to maximize used space. Now, I have a choice.
I can say "make the height 50%" (as that maintains the aspect ratio), but that means that the image will be half the height of the document / paper-- no good. I can say, make it 500 pixels tall, which renders on the screen nicely, but on paper, it will be
skewed, because the paper it's necessarily 1000 pixels wide. Ah-hah, what about using an expression to set the height; surely that must work! No. The expression gets recalculated BEFORE the document is applied to the paper media, so it's just as before.
What the hell am I supposed to do here?

Sorry, but I'm really stuck, and I could really use some help with this. Or a pointer to somewhere I might get a little help.
Also, if the problem's not clear, please say so, and I'll try to restate it.
I can also provide some sample HTML, if that helps.
I THINK I understand what you're getting at, but just to be safe before we start assuming, can you just post a link to your app or the section that is doing the printing?
Let's give this a shot. Hopefully Channel9 won't munge up the HTML too much.
OK. The image itself should be 1500 pixels wide by 750 pixels tall, for purposes of this example. Give it a black border so you can clearly see what's going on.
The fact that there's a DIV, SPAN, and another SPAN there is due to supporting code-- stuff which handles rendering markups, etc. It expects a certain structure, and I can't toss that away.
The SPAN ID'd as FRAME frames the image (duh?). I can use this or the image style itself to control the size of the image.
If you fill in the image and try printing (at least with "letter"-sized paper-- 8.5" by 11"), the resulting image aspect ration will be skewed. On screen, the image is 2:1. On paper, it's more like 2.09677:1.
If I specify 50% height for the FRAME span, then the image is stretched to 50% of the paper or window height.
It's also worth noting that I have no control over the dimensions of the paper media-- it could be letter, but it could also be legal, or A4, or whathaveyou.
