[Plugin: WordPress Print This Section] Print This was unable to locate the section you requested.

Chiming in that I’m getting a similar issue: https://kpcw.org/community/coupons/

Just a quick update on what my issue was, and how I hacked the plugin to get it to work…

The site has a Coupons custom post type, and within each coupon I’ve added the [print_this] shortcode. I then have a page that displays each coupon.

The very first post would print correctly, but the remaining ones would give the error @creagtiondesignstudio mentioned. The plugin seems to be able to mark each section with a printsec variable. When I click on the print button for each individual coupon the link is taken to the single post page for that coupon. Coupon #2 would then have a printsec=2 when there’s only one section to print on that page… manually changing the variable in the url to 1 would allow the page to work correctly.

I ‘fixed’ it by editing class-wp-print-this-plugin.php. On line 170, change:

$print_this_link = get_permalink( $post->ID ) . '&printthis=1&printsect=' . $print_this_counter;

to

$print_this_link = get_permalink( $post->ID ) . '?printthis=1&printsect=1';

I don’t like editing plugins like this, but it works for me now…
