Dear Mouser,
try changing the default DPI in the options to something smaller:
I think the smaller the DPI, the larger a screenshot will be considered when brought into your word processor.
You can also change the DPI of an existing image from within the SpecialFX -> Adjust color + dpi dialog.
Let me know if this solves it please

Hi. Your solution seems to be a workaround because it sacrifices print quality (i.e. DPI) for the image print size. Sorry, if you are offended.
I found out how the image print size is calculated. It's related to the DPI mentioned. This is tested using following settings: Image Format - PNG (max compression).
Let's say the image dimensions is 1024 x 768 pixels and Screenshot Captor's Default DPI is 100.
Image's Print Size
= (image width / DPI) x (image height / DPI)
= (1024/100) x (768/100)
= 10.24 x 7.68 inches
If Default DPI is the usual 300 for image dimensions of 1024 x 768 pixels, the image's Print Size will be around 3.413 x 2.56 inches.
This means the workaround is not that convenient if the screen captures size varies.
Looking forward to your reply. Thanks you for helping.
