You can choice between three ways:
1. If you want to print form exactly as she looks at the screen (with same resolution), use PrintForm method of Form object.
2. If you want to print some data without form (typically loaded from database), add report to project, design it to look as you like and populate them with the same data.
3. If application isn't uses database or every print will look different, you can dynamically print text on printer using Printer object and Printers collection.
