@vvPeterJones I switched Settings>Preferences>Print from “No background color” to “Black on white” and the print is much better.

Even if the shorter, similar string was after the longer string, the same Regular Expression (Regex) can be used to get the same result:- Input abcdefghijklmnopqrstuvwx abc Output abcdefghijklmnopqrstuvwx ABC Explanation: The abc.*xyz preceding the (SKIP)(*F) in the Regex helps skip the long string starting with abc and ending with xyz and matches the other abc in the shorter, similar string! By using that Regex (mentioned in my previous post, just above this), the abc after the (SKIP)(*F) is matched, found and replaced.
