       in duplex mode the sheet is alread in process, so there are some
       commands which must not be sent to the printer for the 2nd page,
       as this commands will cause the printer to eject the sheet with
       only the 1st page printed. This commands are:
       \033&l%dA (setting paper size)
       \033&l%dH (setting paper tray)
       in simplex mode we set this parameters for each page,
       in duplex mode we set this parameters for each odd page
       (paper tray is set by "hpjet_make_init")
