screenshot
I want to put a (non-image) portion of my website on a t-shirt, and to do so I need a high-resolution image of the relevant part. My thought is to tell some utility "take a screenshot of this webpage at such and such resolution" and then cut out the part that I want.
Is this the right approach? Does anyone know of such a utility?
The free version of FastStone Capture will do this.
Use the 'Capture Scrolling Window' function (which also works on web pages):
You can do it with Firefox and 2 extensions: Web Developer and FireShot.
Once both extensions are installed, go to Tools - Web Developer - Resize - Edit Resize Dimensions... .
Add a new size, 4000 x 3000. check "Resize the viewport" if you want only the page content to be 4000x3000. If you don't check it, the complete window of Firefox (with toolbars, menu, ...) will be set to this dimension.
Once at the correct size, go to Tools - FireShot - Capture Entire Page and ... . Select an action, like Save for instance. It will save the page content that has been set by Web Developer to the desired size.

You could print the page to a PDF document. This way, the text is rendered using vectors and will hold up much better in high resolution print.
Most print is done in 300dpi. Text will go as high as 1200 or even 2400dpi sometimes. Your screen on the other hand is typically 72 - 96dpi. So, if your page is text-heavy, it'll end up looking a lot sharper and crisper printed compared to its on-screen version.
