Like when Americans say "guys", perhaps no discrimination was intended.

It shouldn't matter how the poster is assembled, assuming it will not
resample the image in some gross way like Internet Explorer does, for
instance.

You might discover even more flexibility if you use Image Magick. The
'import
command, to be more precise.

The scanner is able to handle a greater density of pixels; printers
likewise. The screen will output the contents of the frame buffer and
unless you use vector graphics, your image will always be discrete. Put
differently... [see below]

11cm (in terms of width) is the most you can get on the paper while
retaining the information in the original image.

This may still be better than another program that will not interpolate the
image. I don't know Scribus, but it might have that undesirable effect. I
suggest that you rescale your screenshots in the GIMP before importing them
into Scribus. That'll make more or less the best-quality screenshots you
can hope for.

In that case, Scribus does not shrink the images gracefully (much like in
the Internet Explorer analogy mentioned above). You need to pre-process
(downsample) the image/w in the GIMP before importing it/them. Set it to
the desired size so that you don't have to re-size any objects in Scribus.

Hope it helps,
