Printing Gantt/Exporting to PDF Not Working

I've been trying to print my gantt chart and all that happens is a new window will pop up in my browser and never load anything.

I'm not sure what to do -- it's a brand new sheet with not a lot of data on it, I've changed the print settings multiple times, I've adjusted the gantt view.

The only thing that has worked was selecting individual rows to print, but I couldn't get it to print (or even load in the separate browser window it opens) more than 14 rows (2 parent, 12 children) at a time even though there is plenty of room left on the paper. It will also only load specific combinations of rows.

For some reason it will export to JPG, but it looks very low quality.
