请问，在 Linux 中，如何将 Ghostscript 程序的输出直接输出到我的 HP LaserJet 打印机？我的最终目标是绘制按比例绘制的地图自然地球数据。
打印机的测试页非常完美，毫米刻度与我的尺子完全匹配，因此用于生成打印机输出的软件必须已经存在。
这是我的测试程序，绘制一个 86.6 (x) x 173.2 (y) mm 的矩形

这就是我尝试过的方法和结果。由于我没有使用文本，所以到目前为止我忽略了错误消息：

它在屏幕上很好地显示了矩形，但在打印机或其打印队列中没有任何内容。
我可能在这里遗漏了一些明显的东西，有人可以帮忙吗？如果这个问题已经在某个地方被问过并得到了回答，我们深表歉意。
