Hi guys. I’m a new player to anti-Idle, and I’m making a small guide on the money printer for new players like myself.
A lot of newer players are bothered by how much it costs to upgrade the money printer. Here are a few facts I’ve gathered about the money printer.
The formula:
power = 320 * sqrt(level) * ((printerLevel – 1)/32 + 0.25)
power = YC per print
level = game level
printerLevel = printer’s level
sqrt means “square root”.
The printer prints every 10 seconds when it’s at 200 charge, without the perk.
Is it worth it in YC?:
From the above, one can deduce that upgrading the printer’s level by 1 will increase the power by:
powerincrease = 10 * sqrt(level)
The cost of upgrading a printer’s level from printerLevel to printerLevel + 1 is:
cost = printerLevel * printerLevel * 20,000
So the total number of prints required to make up for the cost is:
printerLevel * printerLevel * 2,000 / sqrt(level)
The time required to print once is:
time = 2000 / printerCharge
The time also seems to be lower bounded by 5 seconds.
Here’s a graph showing how much time you’d require at a few different levels from 1 to 24. This graph assumes that your battery is, on average, at 100 power. Multiply the graph accordingly to the power you believe your battery is often at (e.g. if it’s always at 200 power your required time is halved).

Is it worth it?
At lower levels, the printer’s return on investment for YC may not be as high as other sources of income. Here’s an example. The 1st extra garden plot costs you 1 mil YC, which may be less than 70 free tree harvests (70 minutes). With garden XP and plot XP this may be reduced further. The arcade and stadium quickly pay back their costs as well, if you play the games. All in all, printer upgrades are a fine choice after your garden is fairly well-upgraded and you have most of the other features.
However, don’t forget that the printer also prints GC (and BC with the perk).
Miscellanea
If you have the printer battery card, it keeps your power at around 400, which almost doubles your reward from printers (and you can idle with it too).
I did not consider the interaction between epic skills, the ascension perk, and the printer.
Thanks to ValentyneSmith for encouraging me to make this guide and Rellian for helping me with it.
