Ink prices are high for end consumers, I bet the US gov does not use an HP-xx for printing but rather big systems where ink price is less than paper.

I have been visiting a newspaper printing factory and they said the ink price was a LOT LOT cheapear than the paper which cost a lot to them.

Ink is expensive for end-user consumers, not for big printing systems.

I would love to see optimization guides with actual benchmarking.

It's like saying `for(var i=..` is faster than `.forEach` without given any numbers.

Always test for performance, do not blindy follow guides or copy paste configuration files in your web server.
