Property. Reflection can mediate between the page width, as specified by the host, and the printer to assure that the printout will fit correctly on the page. Reflection does this by scaling. If the host does not define a page size, or if Override host page format is selected, the page width is derived from the Columns setting on the Page tab in the Print Setup dialog box.
Setter: public void setBoolean("fitHostPageX", boolean scaleWidth)
Getter: public boolean getBoolean("fitHostPageX")
