Kodak ESP 2150 AIO Printer & Scanner Setup for Linux

The drivers and instructions were originally written by Paul Newall and obtained from Sourceforge (which requires an obscene amount of 3rd party scripts to be whitelisted just to get to the downloads) - so I'm posting these to Github incase anyone else with this printer needs easier access to the install instructions. I also had to do a few extra steps to get the scanner working on Debian, so I compiled my steps with Paul's.

These are the steps taken to get both the printer and scanner working on Debian; if running a Debian derivative like Ubuntu or Mint, the steps should be identical.

Although these steps were for the Kodak ESP Office 2150, nearly any supported printer should work with these steps (except for the part where you obtain & upload the .ppd driver; if using a different model printer, snag your particular driver from the project's Sourceforge page).

Instead of logging into a remote server long-form, like ssh -i ~/.ssh/angela root@[host] -p22 ... make shortcuts!

...and you're in.

Find & Replace content in your .git/config recursively

Useful for when you change handles or mistakenly run a global config command.

In your terminal, run:

sed -i -e 's/find_this/replace_this/g' ~/Github/angela-d/*/.git/config

Replace find_this with the entry you want to change

Non-root user access to Apache logs

Instructions applicable for Debian or Debian deriatives like Ubuntu. To use for other distros or directories, simply switch the affected directories in the steps.

In this example, the user group is "angela," change that to whatever group you wish to grant access, like "devs"

As root, set the acl:

setfacl -m g:angela:rx /var/log/apache2/*
