Best DarkRP money printers addon?

It depends on what you want to go for really.
If you want something close to the classic printer I can recommend Elegant, Clickers, Color or my personal favorite rPrint

If you want something a little bit out of the box I can recommend Owains Tier Printers, One Print, Argon or S-Printers

Hope this helps! If you need any script recommendations I've used about %50 of what's on gmodstore, feel free to shoot me a pm or add me on discord @AligatoR#9178
