Answer 1

;printf AX doesn't work and i want to print the contents of AX

You haven't shown us what PRINTf is supposed to do. So all of your PRINTf AX macro calls could be OK.

But your program does have 2 errors that prevent it from executing correctly.

1. A .COM program starts executing from the top but that's where you have placed your data. This must not be executed! So either place the data below the code or jump over the data.
2. The data you use is word sized and thus you need to add 2 to the SI register when iterating over the data.
