Brother DCP-T420w

Hello guys…
I’ve got brother dcp-t420w printer in my office. The cups and the manjaro-printer can detect correctly the brother dcp-t420w printer. But, I can’t find the driver on their list.
I’ve tried to search the driver from the brother website and found only 2 types of packages which are .deb and .rpm. Download the deb type as in case must build from that.
Tried searching the driver in the aur and found a bunch of dcp-txxxx drivers but the right one isn’t there.
Because I don’t find the right driver, I pick the close one which is the dcp-t510w and installed it into my working laptop.
Finish installing and setting up the printer through cups, I do the test print and found the printer is working but the printing result is stretched, so it is not comfortable to read the printing result.
What is supposed to do to make the printer works? Can anybody here help me?
