I have to use the bibliotèque printer to post the properties of the imprimente but the page to post my permit not to make modifications on these proriétés especially the mode of imprission (recto or back). I have to use the component simpleGraphe1 to draw the recto of my document and simplegraphe2 to draw the back. I have a imprimente which can print in recto and back then I want to leave the choice to the user to print the recto anly or the recto/back together. how I must make, be that I must read the drivers of the imprimente and how I makes for that.
thank you in advance.
