Not an issue here as the OP stated the images are In Line with Text. What
you're referring to is floating images (those with some form of Text Wrap
applied). Using text wrapping effectively removes the images from the
content layer of the document & places them in the Draw layer. Sections
really don't have much to do with it unless there is some corruption.
Section breaks can corrupt & result in the graphic content within failing to
print. That would explain why removing the section breaks enabled printing
the graphics. Any time there are images in a document which contains section
breaks the breaks are "around" the images -- an image has to be in one
section or another whether it's In Line or not. If the image is In Line it
is in the same section as the line of text in which it appears. Floating
images, OTOH, can appear in one section but actually be anchored to a
paragraph in a different section. If the anchor paragraph isn't included in
the selection the graphic won't print.
Without specific insights it's difficult to speculate as to exactly what
factors may have been working against you. Objects in a linear flow of text
can be very difficult to control even when everything is going well. The
fact is, however, there are quite a few variables that can make it
exceedingly difficult to manage them. This web page along with the links at
the bottom of it may provide some useful information:
