Algebrator worksheets can be printed just as in any other program. However, there are some details that need to be taken into consideration.
Imagine you have just solved this simple problem:
If you click the 
button you will see a dialog box. There, you can select the printer of your choice by selecting the "Advanced" button. However, before doing this, you should decide whether you want to print only the solution process or explanations as well.
If you only want to print the solution process (i.e. just what the above image shows), then do not mark the "Print Explanations" checkbox. This is how the top part of the printed document would look:
If you mark the "Print Explanations" checkbox, then this is the expected output:
This document might be slightly difficult to read at first glance, but this is because we include each and every explanation Algebrator provides for the entire solution process all at once. Typically, more than one simplification takes place within one single step. That is why, on each step, each part of the expression involved in a transformation is framed and labeled with a number that corresponds to the number of the explanation that describes that step. In the image above, you can see how in Step 1 a single transformation takes place (i.e. adding "-2" to both sides of the equation). That is why only one explanation is printed for that step and the frame surrounds the entire equation. However, Step 2 involves two transformations. In this example, it is the same transformation that is applied twice (once on each side of the equation). That is why there are two explanations printed for Step 2.
