Can’t hide sections?

you can only use the do_not_print attribute once per shortcode. Try something like:

[print-me do_not_print=".entry-footer, #comments" /]

can you dig it?

Hmm… can you share a link?
do you have a caching plugin installed?

OK, it is working, it’s just that multiple articles are being printed.
try using the target attribute to print only the current article:

[print-me target=".post-%ID%" do_not_print=".entry-footer, #comments" /]

By the way, you can define both the do_not_print and target attributes globally in the plugin settings, so you do not have to include them on each shortcode.

Huzzah! Glad it worked out.
