This is a brief tutorial to make the Brother DCP-7065DN printer/scanner work on Arch. It is largely a duplicate of the tutorial for the Brother HL-2030, with changes specific to the Brother DCP-7065DN.
Download Printer drivers
If you previously tried to install the printer in CUPS, remove it.
Install the necessary dependancies :
$ pacman -S cups ghostscript gsfonts
Then create a temporary directory. Then you must download the official LPR drivers from the Brother website into that directory. Click here (and agree to their terms). This is an RPM archive. You have to download the cupswrapper file here (and agree to their terms). This script creates the filters and PPD file for CUPS automatically. It's an RPM archive too.
Extracting the RPM files
Now you need a small script called rpmextract which allows you to get the files included in the RPM you've just downloaded. Log in as root and execute :
# pacman -S rpmextract
Extract both RPM files :
$ rpmextract.sh dcp7065dnlpr-2.1.0-1.i386.rpm $ rpmextract.sh cupswrapperDCP7065DN-2.0.4-2.i386.rpm
It should give you two directories : usr and var.
Editing files to make it work with Arch
Arch Linux uses its own file system organization, so you have to edit some files. Use your text editor (i.e. vi) to open the file named cupswrapperDCP7065DN-2.0.4 If you created the temporary directory "tmp" in your home, this file will be in /home/(your user)/tmp/usr/local/Brother/Printer/DCP7065DN/cupswrapper/cupswrapperDCP7065DN-2.0.4
In this file, you must replace all the /etc/init.d/ occurrences by /etc/rc.d/ and /etc/init.d/cups by /etc/rc.d/cupsd.
Once you've finished this step, copy all of the files to their corresponding directories in your file system :
# cp -r /home/user/tmp/usr/* /usr # cp -r /home/user/tmp/var/* /var
Installing the driver and printer
Go into /usr/local/Brother/Printer/DCP7065DN/cupswrapper/ and run the cupswrapper file as root :
# cd /usr/local/Brother/Printer/DCP7065DN/cupswrapper/ # ./cupswrapperDCP7065DN-2.0.4
It will stop the cups daemon if it's running, and restart it.
Configure the Connection
Now go to the CUPS page : http://localhost:631/
Under the Printers tab you should see a DCP7065DN printer automatically installed and configured.
Click the printers name (DCP7065DN) and in the administration drop down choose "Modify Printer"
Select "LPD/LPR Host or Printer". The next page prompts for the connection string. Enter: lpd://<Your Printers IP Address>/BINARY_P1
And thats it. Check out pages for similar printers for Scanner setup.
