CUPS Does Not Start at Boot

I have a printer over a wireless connection (a HP Photosmart Insert-fancy-descriptors-here 7520). However, after configuring the printer, I realized that CUPS isn't actually running. In order to access the printer, I have to manually start the service with "rccups start" in root, every time I boot.

I have the service enabled under systemctl, and I've tried out a solution from this older thread, but that's gotten me nowhere. I'm currently on Tumbleweed. Is there any log file I should be looking at?

Thanks in advance.
