Here is a mini graph that from what I know about with basing with litteraly a few of the richest friends I could find.
Gold Plated Printer
Prints $1,000 per second.
Prints $60,000 per minute.
Prints $3,600,000 per hour.
It's worth $20,000,000.
You have to upgrade it to maximum level yourself.
GenCorp Printer
Prints $800 per second.
Prints $48,000 per minute.
Prints $2,880,000 per hour.
It's worth $20,000,000 if i'm not wrong.
It's fully upgraded to maximum level when you place it down.
Technically the Gold Plated Printer prints more money and is better, But you use less money on the GenCorp Printer.
