Solved issue

I have the drivers downloaded via tarball, as that's the only option they give for .deb files. I'm not too familiar with tarballs, and often avoid them, because I've found them annoying to work with (as you'll see). I follow the instructions on Brother's website (as seen here: https://support.brother.com/g/b/dow...s&os=128&dlid=dlf006893_000&flang=4&type3=625) and they tell me to open a terminal and go to directory I downloaded the drivers to using the CD command. I type in CD Downloads and I somehow get an error message saying CD: command not found. I've been using Linux (particularly Mint) for about 12 years, so I know it sounds silly and amateurish for me to get stuck on a problem like this, but I honestly can't understand what I'm doing wrong, being that's a extremely simple command. Just to make sure I am doing nothing wrong, I went to this forum to verify I typed it correctly, https://askubuntu.com/questions/179681/cd-and-cd-commands-not-found-how-do-i-use-the-cd-command, and then I tried using the examples they gave: david@david-ThinkPad-X200-Tablet:~$ CD Downloads CD: command not found david@david-ThinkPad-X200-Tablet:~$ CD Downloads CD: command not found david@david-ThinkPad-X200-Tablet:~$ CD .. Downloads CD: command not found david@david-ThinkPad-X200-Tablet:~$ CD-Downloads CD-Downloads: command not found david@david-ThinkPad-X200-Tablet:~$ cd downloads bash: cd: downloads: No such file or directory david@david-ThinkPad-X200-Tablet:~$ cd-downloads cd-downloads: command not found david@david-ThinkPad-X200-Tablet:~$ cd ..downloads bash: cd: ..downloads: No such file or directory david@david-ThinkPad-X200-Tablet:~$ cd dirname bash: cd: dirname: No such file or directory david@david-ThinkPad-X200-Tablet:~$ cd ~/downloads/ bash: cd: /home/david/downloads/: No such file or directory And they still somehow don't work. Does the terminal in Mint need to be configured a certain way before typing this command?

you got pretty close with a couple of those. you should be able to use either of these:

Code:
cd Downloads
cd ~/Downloads

I used the first one and got it to work. Thanks! Its amazing how a simple miscapitalization can trip people up.

Now I'm confused on this part where it wants me to specify the device URI. Here's a list, but I don't know what to choose:
0: beh 1: cups-brf:/ 2: https 3: ipp 4: ipps 5: lpd 6: socket 7: serial:/dev/ttyS4?baud=115200 8: serial:/dev/ttyS5?baud=115200 9: http 10: hp 11: smb 12: hpfax 13: ipp://Brother%20MFC-L3770CDW%20series._ipp._tcp.local/ 14: ipps://Canon%20TR4700%20series._ipps._tcp.local/ 15: dnssd://Brother%20MFC-L3770CDW%20series._ipp._tcp.local/?uuid=e3248000-80ce-11db-8000-b422009d5c50 16: dnssd://Canon%20TR4700%20series._ipp._tcp.local/?uuid=00000000-0000-1000-8000-0018dc0071fe 17: socket://192.168.1.65 18: lpd://BRWD88083B041E2/BINARY_P1 19 (I): Specify IP address. 20 (A): Auto. (ipp://Brother%20MFC-L3770CDW%20series._ipp._tcp.local/)

it's been a while since i set up a printer so i don't recall a lot about the different protocols designated by the different uri's. this page has some info about them in the "Choosing a Network Protocol" section: https://www.cups.org/doc/network.html

i seem to recall IPP being recommended because:
IPP is the only protocol that CUPS supports natively and is supported by most network printers and print servers. IPP supports encryption and other security features over port 631 and uses the http (Windows), ipp, and ipps backends.

That didn't work because I got this error message lpadmin -p MFCL3770CDW -v ipp -E lpadmin: Bad device-uri "ipp".

are you running that lpadmin command manually or does the driver installer run it after you choose a uri? this is an example from the lpadmin manual page (man lpadmin):

lpadmin -p myprinter -E -v ipp://myprinter.local/ipp/print -m everywhere

so it looks like you would want to choose this option from the ones you listed: ipp://Brother%20MFC-L3770CDW%20series._ipp._tcp.local/

It runs it after I choose it. I'll try your recommendation.

I did it, but whenever I enter my IP address after being prompted to, it sends me back to creating the bash script

i'm not familiar with the installer you are running nor do i have a printer to test it with so i would need the following info to try and help further. does it say why it needs your ip address and what bash script does it send you back to create? does mint mate have a Printers program in the menu (mint xfce does) and, if so, is your printer listed there?
