Of course, I know it needed samba, but I had difficulty sharing one to Windows PC which I didn't really get into much since the day I moved away from Windows. This was what I did to get it work.
$ /etc/samba/smb.conf
Find these lines and uncomment them; if you can't find, type.
printcap name = cups
printing = cups
`[printers]` section should look similar to this
[printers]
comment = All Printers
browseable = yes
path = /var/spool/samba
printable = yes
public = yes
guest ok = yes
create mask = 0700
use client driver = yes
path = /tmp
Then you have to restart samba.
$ sudo service smbd restart
For some, you might have to use `samba` instead of `smbd`. That's varied by distros. However, after adding printer to your Windows box, you should be able to print. I find it's easier to navigate to ```\\linux-box-name``` in file explorer. Find printer there, then right-click to connect and add there. Add printer via Devices and Printer and auto discovery thing isn't impressed me 99% of the time.
