Called to let code submit custom PostScript code (e.g. apreamble:= readdatastring(...)), for tasks not covered by the reporting components — for example, drawing a barcode with a third-party PostScript barcode generator by issuing raw PostScript commands from a widget's onpaint (cast the canvas to tpostscriptcanvas and call pscommand).
