In the two upper textfields, the name of the class or method being printed is displayed. You can choose serveral options using the tabs.
In "Class/Method", you can define if the entire class or only the active method will be printed. You can also choose if the JavaDoc - Comments shall be printed, too.
In "Margins", the margins on the left and right side of the paper can be defined (in inches). Preset values are 0.75 for all four margins. If these values don't work with your printer, you have to try a little bit.
"Font" defines the font height used for printing. The font type is Courier and cannot be changed.
In "Tabulator", you specify the amount of spaces that represent a tabulator.
After pressing "OK", another window opens that demands further parameters. This window varies in the different operating systems.
