+# Introduction
+
+For those of you who don't know, Student Finance England provide free printers to more or less all disabled students
+via their Disabled Students' Allowance (DSA) funding. The printer they provide is a Canon PIXMA TR4755i (or at least,
+it was for me).
+
+Printers are known for being rather unreliable pieces of technology, particularly on Linux (although, historically,
+I've honestly found printers to work much more reliably and without need for troubleshooting on Linux than Windows).
+So I was quite concerned when the government sent me a free printer, that I would not be able to use it. Luckily, after
+a few short hours of wrangling things, I managed to get it working via USB (I've not tried network printing, but will
+update this post once I do). I wanted to make this post to save people time if you are also a disabled student, or
+happen to have this model of printer for another reason.
+
+# Guide
+
+## Install CUPS
+
+Firstly, install CUPS and run the CUPS daemon. The commands for this will depend on your distro and how you are
+managing services/daemons, so I will leave this to you to figure out. Your distro's wiki or forums should have info on
+how to set up CUPS.
+
+## Install the Canon InkJet Printer Driver for Linux
+
+Then you will need to install the Canon InkJet Printer Driver for Linux. Depending on how this is installed, you will
+connect to the printer in two different ways.
+
+### Without a package manager (RPM or DEB)
+
+Canon have Linux driver downloads [here](https://www.canon.co.uk/support/consumer/products/printers/pixma/tr-series/
+pixma-tr4755i.html?type=drivers&os=all). They provide downloads for systems using .debs and systems using .rpms.
+
+For setup, you should ideally refer to Canon's own manual, which is provided as a tarball [here](
+https://www.canon-europe.com/supportproduct/tabcontent/
+?type=manuals&detailId=tcm:13-1641056&productTcmUri=tcm:13-2320166). However, as this is not the most accessible
+format, I'll provide the current version of instructions here on my blog:
+
+Firstly extract the tarball downloaded from Canon's website, and change directory into the newly expanded directory.
+
+    $ tar xzvf cnijfilter2-versionNumberHere-rpmOrDeb.tar.gz
+    $ cd cnijfilter2-versionNumberHere
+
+Canon provide an install shell script which will walk you through setup:
+
+    # ./install.sh
+
+When installation is complete, you should be walked through registering the printer. Afterwards, the printer should be
+recognised by CUPS, and you can use any system print dialogues to print to the printer.
+
+### Via the AUR
+
+The AUR provides a `cnijfilter2` package. Installing this package provides the `cnijlgmon3` utility, which you should
+run as root:
+
+    # cnijlgmon3
+
+The output should say something like:
+
+    direct cnijbe2://Canon/?port=usb&serial=60-12-81-A7-7D-34 "Canon TR4700 series" "USB Printer #1 with status readback for Canon IJ"
+    direct cnijbe2://Canon/?port=usb&serial=60-12-81-A7-7D-34 "Canon TR4700 series FAX" "USB Printer #2 with status readback for Canon IJ"
+
+Copy and paste the URL starting with `cnijbe2://Canon/` into the following shell command:
+
+    # lpadmin -p PrinterNameHere -p /usr/share/cups/model/canontr4700.ppd -v "URLhere" -E
+
+`PrinterNameHere` can be whatever you want; it's just how the printer will be named in any print dialogues.
+
+The `.ppd` file should have been provided by `cnijfilter2`.
+
+Replace `URLhere` with the URL you copied above, from the `cnijlgmon3` output.
+
+Afterwards, this printer should have been added to CUPS, and you can print to the printer using any system print dialogues.
