DIY Continuous Ink Printer = Unlimited Free Printing
Instead of paying for absurdly priced printer cartridges, build yourself a Continuous Ink Printer (CIS) which can be made by hacking an old printer to suck ink from external reservoirs. You can get the raw ink for dirt cheap so it’s essentially like unlimited printing for free (besides the paper). So now you can actually print your collection of pirated books! 
A CIS is relatively easy to create, just take an Epson Stylus 760 (a surprisingly hard to find printer) and make a few modifications to it. A tutorial walks you through the build process so you can make your own.

Or, just get a color laser for about $400 with full size toner cartridges (Dell), and print 5000 pages for no cost.

Not really free. The heads on cartridges eventually wear out. This can cause a real mess, and possibly damage to your printer if you keep printing with damaged or worn out heads.

Well of course it’s going to wear out eventually but it’s free for ages.

Imagine your inkjet printer was your car. If your car needed an oil change, would you say screw this i’ll just save money and top of the oil in my car or better yet forgoe putting the right grade of oil in my car (whatever is the cheapest). As an IT tech, I see this all the time, clients blaming the printer manufacturer for their el cheapo refilled cartridges not working or better yet creating a nice big mess inside the printer. Printer manufacturers spend millions of dollars in R&D and patents to get their ink formulations right. I can guarantee you the ink being refilled in your ink cartridges is not the same genuine ink you would be getting from manufacturer. One time an irrate client blamed me for his refilled ink cartridge not working in his printer. Low and behold I put a genuine ink cartridge in the printer in front of the client and the printer worked. The client just yelled at me and called me incompetent. Sheesh.
