是否可以通过 PosPrinter 类获取 pos 打印机的 dpi,或以像素为单位的最大宽度,或以 mm 为单位的纸张宽度?我在任何地方都找不到这些属性。谢谢

If the printer supports page mode (check CapRecPageMode), PageModeArea may be used to figure out the width in the desired units (set MapMode to choose the units).

If CapRecPageMode is false, use RecLineWidth (and MapMode) for the widest RecLineChars supported by your printer.
