Description Dimitar Dobrev 2012-01-10 05:38:53 UTC
Created attachment 1155 [details]
A test case

Steps to reproduce:
1. Have a printer connected to a Windows network;
2. Add the printer to a mac (through System Preferences -> Print & Fax -> etc.) - this will require a Windows user with his password to be entered once;
3. Run the attached sample with a Mono between 2.10.5 and 2.10.6 included.

Expected results:
An empty page is immediately printed.

Actual results:
The document stays indefinitely in the printing queue with a text "On hold (authentication required)". To print, each time the document must be selected in the printing queue, then clicking "Resume" will show a dialogue for the user and password used when adding the Windows printer and after confirmation printing will complete.

As hinted above, version 2.10.4 and less (excluding, of course, versions that do not work at all on Lion) work fine. I cannot check 2.10.8 because there PrintDocument.Print causes a crash, as described in http://bugzilla.xamarin.com/show_bug.cgi?id=2734.

Currently Windows.Forms on the Mac has no maintainer.

We encourage the community to submit patches to it.
Comment 2 Dimitar Dobrev 2012-01-13 20:54:00 UTC
It's not a Windows Forms application, it's a GTK# one but which uses System.Drawing.Printing. Sorry for not clearing that up initially.
Comment 3 Miguel de Icaza [MSFT] 2012-01-14 15:39:05 UTC
We consider System.Drawing part of the Winforms stack, so we really hope someone in the community looks for the fix and provides a patch.
Comment 4 Dimitar Dobrev 2012-01-24 03:19:41 UTC
Are there alternatives for printing on the mac then? Or do you have a guess where could the problem be? This is a blocker issue for us.
Comment 5 Miguel de Icaza [MSFT] 2012-01-24 08:24:26 UTC
Hello Dimitar,

There are a few options:

* Engage a consultant that can develop/fix the existing code base to ensure that it works and submit the code to us for distribution.

* Use MonoMac's APIs to print.

* Generate a PDF file, and then use Applescript to load the PDF into the Preview program and instruct it to print it.
