Cannot Access print-manager Interface In KDE

Question

Hello all,
First of all, I have print manager installed. I've tried uninstalling and reinstalling, but the problem still persists. The problem is that no matter what I do, there is no option in the System Settings app on KDE to manage printers. I realise that I can just use the CUPS interface, but that leaves a lot to be desired for me.
I have spent hours scouring the web for any information on this, and it appears that the most common reason for this problem is that people don't have print-manager installed in the first place. That is definitely not the reason I'm having the problem, however.

as unprivileged user, it won't open and returns the following:
$ kcmshell5 kcm_printer_manager
kf5.kservice.sycoca: Trying to open ksycoca from "/home/aaron/.cache/ksycoca5"
kf5.kservice.sycoca: Trying to open global ksycoca from "/home/aaron/.local/share/kservices5/ksycoca5"
kf5.kservice.sycoca: Trying to open ksycoca from "/home/aaron/.cache/ksycoca5"
kf5.kservice.sycoca: Trying to open global ksycoca from "/home/aaron/.local/share/kservices5/ksycoca5"
kf5.kservice.sycoca: Still no database...
Could not find module 'kcm_printer_manager'. See kcmshell5 --list for the full list of modules.
As sudo, it opens the window but says, "print service is unavailable. Bad file descriptor." and I am forced to exit the window. Outputs this in terminal:
$ sudo kcmshell5 kcm_printer_manager
kf5.kservice.sycoca: Trying to open ksycoca from "/home/aaron/.cache/ksycoca5"

Thanks for the quick help, by the way!
