Hi
OK I undertand the limitations.
I have done some research and found a BRILLIANT solution for you. Using Infopath 2003 you can go into form options and firstly enable "export to web" function you can find out more about this here:
http://office.microsoft.com/en-gb/infopath/HP010967451033.aspx
Enabling this creates an .mht file an exact copy of your current view as a read-only file that is viewed through IE. Send this file as an attachment that they can open through IE and print. The view matches exactly the view you are on at the time of export so could include all the formatting. It does not have any sender information when printed AND it does not require the install of any other product.
Downside is that the process is a bit more manual. You could through some effort find a way to code the export to web function, save the result locally, and open an outlook window with the .mht file already attached so your user jsut has to click 'Send' to mail the file.
Coding is not my thing but in the mean time this provides you with a useful solution to clumsily satisfy the remit.
I hope this helps
