各位大侠，上次请都各位高手知道用如下方法得到打印机

;;; Get plotting device list
(defun get_printers ()
  (setq _layout (vla-item (vla-get-layouts (vla-get-activedocument (vlax-get-acad-object))) 0))
  (vlax-safearray->list
    (vlax-variant-value
      (vla-GetPlotDeviceNames _layout)
    )
  )
)

现在不知如何得到和打印机相配套的打印纸的格式,请帮忙指点一下,我对上面那个程式也不是很懂
