Hi ,
Could you please tell the Acrobat version you are using ?
Also update me about the printer with which you are trying to print ?
Have you tried to print earlier and it did not print as per your expectation or you just want to know how would you get the desired 100% black print.
Please try to print and see what is the outcome .
If that does not work then got to file>print>properties>paper/quality>select black and white.
Also go to file>print>advanced>under ink manager choose print black and click OK and see what is the outcome in both the cases.
I guess this would solve the purpose.
Let us know how it goes.
Regards
Sukrit Dhingra
