Aquileo | #12 Printing

Mon, 21 May 2018 02:08:14 -0000

I've studied the source code. The current implementation does not work for these reasons:
1. it tries to create a temporary file in C:\
2. it uses print.exe to send data to a printer, but print.exe only works with LPT and COM printers, so no network or USB support.

I've made a patch which changes the code so that WritePrinter() WinAP function is used to send data to the printer. It was tested successfully on these models:
HP LaserJet 4050N - raw text and PostScript printing work.
HP DeskJet 5740 - only raw text works, this model does not support PostScript.

However, switching to WritePrinter() does not solve other problems with Emacs Windows printing. Regardless of what method is used - print.exe or WritePrinter() - some non-ASCII characters will not be properly printed (because fonts are not loaded to the printer) and some printers will not print anything at all (depends on PDL/PJL support of the specific printer). Proper Windows printing has to be implemented as output to a printer HDC.

With your printer, it may work, but I haven’t tried.

After several years of struggle, I found it very difficult to use printing function in Emacs under MS-Windows.

However, I made printing to PDF possible. It is very tricky and requires Adobe Acrobat, Ghostscript, and GSview 5.0 (http://pages.cs.wisc.edu/~ghost/gsview/get50.htm).

A possible customization would be:

Install Acrobat and use Adobe PDF (the virtual printer) as the default printer. Make sure it works.
Install Ghostscript and GSview 5.0.
Start Emacs with “-Q”. Eval
(setq-default ps-lpr-command (expand-file-name "C:/Program Files/Ghostgum/gsview/gsprint.exe"))

This depends on where you install GSview.

Then M-x ps-print-buffer-with-faces, a PDF file may be generated.

There are other configurations. All of my dotEmacs (sorry for the Chinese) could be found at

Happy hacking,

Printing does noit work. Neither print-buffer, nor ps-print-buffer. Neither USB local printer, nor IPv4 network printer. Using version "GNU Emacs 25.3.1 (x86_64-w64-mingw32) of 2017-09-12". Below is an example of error message.

Aquileo | #11 emacsclient -nw still opens new frame/window

Fri, 14 Oct 2016 13:20:35 -0000

Its unfortunate but it seems you're correct, my research led me to the following:

Note that, due to limitations of MS-Windows, Emacs cannot have both GUI and text-mode frames in the same session. It also cannot open text-mode frames on more than a single Command Prompt window, because each Windows program can have only one console at any given time.

Hello Jason,

Same here. And I think this is the expected beahivor under Windows. Do you have any references that it can work this way?

Sorry,

Chris

Aquileo | emacsclient -nw still opens new frame/window

Thanks for putting this together. As the title says... when I run the emacs --daemon and then try to run emacsclient -nw it opens a new frame instead of.opening in the terminal as expected. I've also tried the -t and --tty flags but the result is the same.

I'm running emacs-w64-25.1-O2-with-modules on windows 10 proffessional if that helps.

Aquileo | #10 Magit Editting Commit Message Is Slow (Lags)

Thu, 02 Jun 2016 06:16:04 -0000

Sorry for that. Some guesses:

The lag may relate to the changes in emacsclient. You can test this by trying the offical version
http://alpha.gnu.org/gnu/emacs/pretest/windows/.
The lag may be caused by garbage collection. You can test this by M-: (setq garbage-collection-messages t) or M-x profiler-start and M-x profiler-report.
Hooks? Timers?
Antivirus softwares?

Sorry for taking so long to respond. I only use this package at work where I'm stuck with a Windows machine. So, I don't often have time to fool around with software.

I just grabbed the latest stable you have released (25.0.94), and the lag is still present. However, the delay is in hundreds of milliseconds instead of thousands of milliseconds.

Aquileo | #9 Request for debug-friendly 25.0.90 pretest version

Wed, 03 Feb 2016 15:36:09 -0000

In my experience, your fears about performance are unbased. The -Og version works fast enough. I urge you to use that version because doing that will help us with testing the upcoming 25.1 release, which, after all, is the main purpose of having the pretest binaries available.
Once v25.1 is out, the official release can be compiled with more aggressive optimizations, of course.

Thanks.
