Hi All, i have a question:
I'm looking to a faster termal printer than the one by adafruit, so i am oriented on this, based on this tutorial.
I'm not very confortable with the rs232 +-12V, i've never used it and i have a deadline very early.
Instead of use a MAX233CPP, could I just buy some adapter like this from 25 to 9 pin and then this from RS232 to TTL?
At that point i would connect the second one to arduino directly.
