HTML Print and lose formatting

[Edward]

I am trying to use HTML print and have lots of problem.  I stored my data in HTML if that matters.

For example, empty paragraph break is missing.  I am using single line spacing, so if I press enter it will look exactly like shift enter.  However if I do:

Line 1 (enter, enter)

Line 2

but the print out will only show

Line 1
Line 2

I think this has to do empty paragraph <p> tag is ignored by IE in the HTML print.  By comparison, this will work:

Line 1 (shift enter, shift enter)

Line 2 (enter, space)

Line 3

I also tried to use native printing, and get this:

Hello Edward,

Unfortunately, we were not able to reproduce the problem you have described.

In our latest official version  - 2012 Q1 SP1 (2012.1.326) Html and Native print seem to work as expected. Could you please confirm that you are using this version in your project? For testing purposes I have used single paragraph line spacing and I have executed your steps, but the printed document looked correct. Could you elaborate more on your issues with Html print and the exception thrown by Native print? We will appreciate if you can send us sample project using a support ticket, so we can further investigate these failures.

Looking forward to your reply.

Regards,
Vasil
