First Installation
To install the addon, download the .zip and drag the "advanced_printers" folder inside that ZIP file into your server's addons folder.
Once that's done, you will need to disable the default DarkRP printer.
If you don't already have the darkrpmodification addon, download the addon from here and install it the same way as above.
Once that's done go into it's folder and go into lua/darkrp_config/disabled_defaults.lua. I would recommend you open it with something Notepad++, Sublime Text or Atom, yet if you have an alternative or just want to use notepad go for it. Any text editor will do really. Once in that file, go to line 83 and you will see something among these lines:
Change the false value to true. This will make DarkRP remove the default Money Printer from the game so that your players should only get access to Advanced Printer's printers.
Now restart your server, and it should be gone.
To configure the addon, go into advanced_printers/lua/advprinters/config and you will see a file called sh_config.lua. Open that up and begin editing!
