Hi,
I've been asked to design a page for print on pre-printed
stationary.(dont ask). Anyway does anyone know of a pts to pixels
converter on the web or is it a simple ratio? Cheers.

Wouldn't that entirely rely on the DPI of your desktop? I've I have an
effective desktop res of 96dpi (say, 2580 x 1600 pixel desktop) with
an image on it, there are going to be a lot of pixels making up an
"actual" 12pt font on screen. If I move that to another screen, the
pixel representation of 12pt could be higher or lower... *shrug*

The DPI that the page will print will depend on the operating system.
PCs tend to print at 96 DPI. Macs tend to print at 72 dpi. Relying on an
HTML page to print as expected on stationary won't work.

If you need reliable page layout to print on stationary, consider PDF.

I did.Unfortunately the easiest way for me to create a PDF was to feed a PDF
component a URL, which brings you back to square one.

Not that I have extensive experience of printing from web applications (I
usually try to avoid it), but every encounter has been painful. Web
applications are a great way of creating maintainable applications, but
printing is the Achilles' Heel. Fingers crossed for better print support in
CSS version X.

Dead easy (for most of it), just use a CSS stylesheet with media=print
and set the units up in mm or pts as appropriate.

Your only real problem is the page print margins, which aren't
settable from CSS. Either make it clear how the users should manually
set this so that their browser print settings match those assumed in
the CSS page, or else use IE and MeadCo's ScriptX ActiveX control to
control them (there might be a more recent or more widely portable
solution too).

Such a thing is fundamentally impossible and inappropriate. It depends
entirely on the user's local environment and settings.
