Trying to get a brother laserjet working with CUPS on a raspberry pi 3

I have a raspberry pi 3 with laterst raspberry pi OS, webmin, samba, and cups installed on it. Have a brother HL-L2300D laserjet hooked up with USB. The printer is listed on the printers page of CUPS. I am having issue with getting the right driver installed on the CUPS server. Downloaded the CUPS driver from the brother website and it had a PPD file that I could use, print test pages doesn't work and when I try to use my tablet I can see the printer listed but again not printing occurs. I know that I am in kind of unchartered territory here. But any help would be greatly appreciated. Doing this for my mom, she got rid of all her PC's and get a new iphone and IPAD so trying to setup this web print server for her so she can print from these devices to this brother laserjet.
