Compare Documents - Print Side by Side view of both documents on one page.

Post by Mirage »

Hi there,

I am trying to print the compare document side by side.
For example, when I compare documents, it gives you a side by side view of left being the old document and right being the new document and it highight the differences on both sides. which is great.

I want to print that view with both documents on the one page having both comparisons instead of only printing the new document with the changes.

Is there an option? or a script? or a function that can be added? or have i missed something here?

Thank you :) :)

Hello, Mirage

This may be difficult to offer, since there are going to be many cases where the page order is changed, or the content shown is not a direct 1-1 for such a simple comparison output, as an example, in some cases, due to duplicated pages, you could see a result like this:

In such a case, simply printing both pages 1:1 side by side may not be the correct method to offer that comparison, instead printing page 1 and 5, then page 2 and 10, side by side is correct, but for pages 3-10, which do not exist in the original, how would we prepare those. Do they print as standalone items, with a blank comparison... sometimes a single page can be detected as a match for multiple pages as well, perhaps in doc B 4 pages were tiled into a single page, so from Doc A, page 5 matches all of pages 5-8. In this case, the connection lines would be crisscrossing and only add confusion on the printout.

Practically speaking, comparison is a process that is only intended, and only presents well in a digital format. It is not designed for, and will not work well in a physical format. We may consider some options, but in practice, I do not foresee this happening.
I will of course pass this along to the Dev team for consideration, but below I have an option you can use to some effect in the meantime:

What you can do instead, if you do wish to a 1:1 page comparison, is a manual visual comparison. Use the "resize pages" tool, and double the width of your pages in both documents. (If the either document has more pages than the other, you will want to add new blank pages to make up the difference before we start)
Choose the "scale" type and set the left (x) value to 200%, then uncheck the scale content option, and snap the content to the one side:
In Document A, snap to the left

In Document B, snap to the right (the other options remain as is, so no need for a change:

Then you use the overlay function, to impose one of these onto the other, and the two will become a single document:

Do not save these documents, since that would overwrite the originals, but you can print a copy of it, before closing them without saving, to see a visual side by side on each page.
When printing, since these pages may be abnormally sized, you can use the "reduce to margins, auto center, auto-rotate" options to ensure that all page content is visible, no matter what paper sizes your printer offers:
