StackPrinter is a website that pulls the main details of a given question, all its answers, comments and votes formatting them in a simple essential printable view.

I've created this micro web application basically to add a "Printer-Friendly" feature to the Stack Exchange Network sites, trying to remove some @Media Print CSS limitations like hidden comments, pagination and empty spaces. (rationale here)

Other features:

  • Addons:
    1. Greasemonkey script - Adds a Printer-Friendly button on question's page (FF|Chrome)
    2. Bookmarklet - Allows you to print a question directly from question's page
  • Favorites: lets you browse and print favorites users's questions from:
    1. The Stack Exchange Network
    2. Delicious social bookmarking
  • TopVoted: top voted questions by tags
  • TopPrinted: StackPrinter top printed questions
  • Deleted: popular deleted questions archive
  • MySE: for printing all your Stack Exchange stuff

    oh man! also, why don't you modify it so it displays the actual value of the link. Displaying just the text doesn't mean a lot unless you can view the URL as well

    the url. Just blue text tells me nothing. I want to see the actual URL so I can type it in later :)

    How about doing what Wikipedia does, and have all the links at the bottom of the page? Then just use [1], [2], etc. in the posts. Commented May 23, 2010 at 7:17

    @sys: I think so - if there were a lot of links, the pages would be much easier to read. Commented May 23, 2010 at 16:04

    Great application -- there are still a few cases where a nice printout beats reading something on the screen. Suggestion: include the original question URL in prominent fashion near the top of the printout. That would be a good reference from the printed page back to the online version.

    @kenorb just add &printer=true at the end of the url if you don't want ads. Commented May 13, 2015 at 14:14

    to be https compliant, it's time to update the bookmarklet regex to ^https?://(.*?)\.com/questions/([0-9]+)/

    I have been using Brett Terpstra's "Answered" (brettterpstra.com/projects/answered) bookmarklet. It offers some of the same functionality, but StackPrinter offers more options for archival purposes. Commented Aug 31, 2017 at 15:16

Stackprinter allows you to print directly from Stack Exchange sites using Greasemonkey script or an handy bookmarklet.
Greasemonkey script adds a Printer-Friendly button to the question you are browsing (Firefox and Chrome both supported).
Bookmarklet is useful if Greasemonkey is not an option and has the same effect of Printer-Friendly button, allowing the print of the question straight from the question page.

Favorites allows you to browse and print your favorite questions or other users favorites.
Stackprinter supports all Stack Exchange sites plus Delicious social bookmarking service.
Just star or save your questions and browse Stackprinter to print all of them later.

    Is there no way to 'print all' questions or answer by a particular user?

I asked this as a question, but apparently the convention is to report bugs/feature requests in the announcement thread. It appears, that the MathJax extension mhchem is currently not enabled in the StackPrinter app. This is rather inconvenient for most of the chemistry.se questions and answers. It would therefore be nice if this feature could be enabled for the StackPrinter app.

Please consider the sandbox on meta.chemistry.se and its printed version (also see the screenshot below). You can see in the first equation of my post the red \ce. I enabled the mhchem package manually via \require{mhchem] after that and the same command renders now.

  • I will take a look at it, is this extension available on Cdn? Commented Apr 21, 2015 at 12:43
  • I do not know what Cdn is. The extension is part of the whole MathJax package. It is probably just a variable that has to be toggled, since it is already available, as the screenshot proves. Thanks for having a look. Commented Apr 21, 2015 at 12:55
  • Oh OK, it should be easy to fix.(maybe tonight) Commented Apr 21, 2015 at 14:39
  • Should be fixed, give it a try. Commented Apr 21, 2015 at 21:15
  • @systempuntoout It works like a charm, thank you very much. Great app! Commented Apr 22, 2015 at 3:10

Here is a small script (stackprinter) which uses Stack Printer from the command-line:

type wkhtmltopdf || { echo >&2 "wkhtmltopdf command is required. Aborting."; exit 1; }
: ${1?"Usage: $0 (url)"}
URL=$1 && shift
HOST=$(echo "$URL" | grep -Eo "([.[:alnum:]]*?)\.(com|net|org)" | head -c-5)
QID=$(echo "$URL" | grep -o "[0-9].*/" | head -c-2)
FILENAME=$(curl -s "$URL" | grep -o "<title>[^<]*" | tail -c+8)
wkhtmltopdf $* "$PRINTURL" "$FILENAME.pdf" && echo "'$FILENAME.pdf' saved."


./stackprinter (url)

Example (tested on OS X):

$ ./stackprinter http://stackapps.com/questions/179/stackprinter-the-stack-exchange-printer-suite
'app - StackPrinter: The Stack Exchange Printer Suite - Stack Apps.pdf' saved.
  • head -c-2 doesn't work on macOS, is the intent to get the first string of alphanumerics out of the URL? I guess sed 's/[^0-9]*//;s/[^0-9].*//' would do that in a single process. Of course, using parameter expansion would do it without any external process at all (but require several steps and maybe a temporary variable).

The default bookmarklet javascript has problems when used with mathoverflow. Because annoyingly mathoverflow ends with a .net instead of a .com. I made some changes so that it could also work with mathoverflow (feel free to improve on it):

  var re = new RegExp('^https://(.*?)\.com/questions/([0-9]+)/');
  var group = re.exec(window.location.href);
  if (group==null)
    re = new RegExp('^https://(.*?)\.net/questions/([0-9]+)/');
    group = re.exec(window.location.href);
  if (group!=null)
    var service = group[1];
    var questionid=group[2];
    alert('Attention: question id not found!');
  • Thanks for your contribution! Perhaps you could replace \.com with \.(com|net)?

  • I know what you mean. I did not know how to make this work with RegExp but I don't think your suggestion works. I think it's a bit more complicated than that. Anyway, I tried it and it didn't work for me.
