A screen printing machine includes a printing execution unit which fills a pattern hole of a mask with solder by sliding a squeegee on the mask contacting a board and thereafter separates the board from the mask. The screen printing machine further includes: a library which stores printing conditions, each of which includes operation parameters of the printing execution unit and corresponds to a combination of options of selection items which include aboard type, a solder type, and a squeegee type; an option display unit which displays the options of each selection item in an image display area; and a printing condition setting unit which reads out, from the library, a printing condition corresponding to a combination of selected options, and which sets the read-out printing condition to a printing control unit which operates the printing execution unit.
