I have an app that creates reports, which are basically HTML. The

I'm porting an older app - that is more of traditional web app.
Reports are displayed in a page - with a UI wrapped around them. When
a user wants to print a report, he clicks a "print" link, which pops
up a window with a printer friendly version (no UI elements). He can
then selects the browser's print command. Works nicely.
I'm trying to figure out how to do that in GWT. I can display a
report. Printing doesn't work well, because it prints all the UI
stuff too.
I've looked into separate popup windows. Most of the messages here
recommend against doing it. Instead they suggest using a Dialog box.
I've tried it and created a Dialog with simply an HTMLPanel. However,
selecting File->Print (in the browser) prints the entire page (the
entire window).
Any suggestions on a way to do this?
Here's one idea I've implemented. It's amenable to arbitrary levels of
complexity.
Your UI posts a request to your server on user action (e.g. a button
click event), and opens the result in a new window:
<button type="submit">
<form action="printTheCurrentReport" _target="_blank" method="get">
<!-- Depending on how you manage sessions, you might want a session ID
token in a hidden field -->
</button>
Reminder: you should have css for print media.
