如何在 OSX 中从 emacs 打印

我已经在 Mac 上使用 emacs 几年了，但一直在使用其他应用程序进行打印。我终于开始深入研究 emacs 打印。我决定设置 postscript 打印。我打印到文件，然后使用预览进行实际打印。这是我的设置。还有人有更好的吗？

。

;; Postscript printing
;;
;; defaults
(setq ps-font-size 9)
(setq ps-header-font-size 8)
(setq ps-header-title-font-size 8)
;;(setq ps-header-lines 1) ;; only use the filename and page number

(setq ps-header-offset 18) ;; margin between header and text in 72nds of an inch
(setq ps-left-margin 36)   ;; left margin in 72nds
(setq ps-right-margin 36)  ;; right margin in 72nds

;; Simple print buffer command
;;
(defun sprint-buffer ()
  "Output a postscript file using the defaults."
  (interactive)
  (ps-print-buffer "~/temp.ps")
  (shell-command "open /Applications/Preview.app ~/temp.ps"))

;; Simple print region command
;;
(defun sprint-region ()
  "Output a postscript file using the defaults."
  (interactive)
  (ps-print-region (mark) (point) "~/temp.ps")
  (shell-command "open /Applications/Preview.app ~/temp.ps"))

;; Setup the postscript settings
;;
(defun sprint-setup (use-headers use-line-numbers use-landscape)
  (interactive
   (list (y-or-n-p "Headers?")
         (y-or-n-p "Line numbers?")
         (y-or-n-p "Landscape?")))
  (setq ps-print-headers use-headers)
  (setq ps-line-number use-line-numbers)
  (setq ps-landscape-mode use-landscape))

答案1

我emacs 24正在使用htmlize-buffer命令。这将生成一个.html文件（具有所有正确的语法突出显示），然后我可以打印或转换为.pdf。

答案2

您将需要较旧的代码longlines.el（当前版本的 visual-line-mode 不能代替 longlines-mode）：  http://www.emacswiki.org/emacs/download/longlines.el

我正在使用 courier，因为它比 times 更好地处理所有大写字母。

我在其中提供了一个是/否选项，作为 ns-read-file-name 错误的解决方法，但 Emacs 团队几周前刚刚在 Trunk 中修复了该错误。因此，如果您构建了 Emacs Trunk 开发人员版本--with-ns，则不再需要是/否选项。
