This should be fixed with cset c9f960441513 (http://hg.savannah.gnu.org/hgweb/octave/rev/c9f960441513) in default.

Tested with XFCE4 on Debian Jessie.

Thanks for the confirmation for both LXDE and XFCE. I can also reproduce with an older GNOME 2 but not with GNOME 3.

The failure to print occurs if a window manager puts a window in the unmapped state when it is minimized or moved to a different virtual desktop. Some window managers/desktop environments do and some do not.

Marking as a duplicate of bug #33180 because it is the same basic problem, unable to print a figure that is not rendered when using FLTK.

I can confirm too (with Lubuntu 14.04 / LXDE).

I can confirm this with Octave 3.8.1 and default 79f69742971a under XFCE, debian wheezy amd64.

No followup comments from OP in about 8 months. Closing as works for me. If this problem persists or returns, feel free to reopen this bug or report a new bug describing the problem in more detail.

This works for me on the development branch (17616:8cc19352fd74). This may have more to do with windowing systems (I use KDE) than with Octave. Test system was Mint, based on ubuntu 12.04, with 64-bit kernel. The critical OpenGL2ps library was libgl2ps0 1.3.6-1.

Generate a plot on screen, then switch to a different virtual desktop, launch print('test.png') command. No PNG graphics is generated

This I tested with the dev version and 3.6.4 on an Xubuntu 12.04
platform (XFCE) on different computers.
The Gnuplot backend does not show this problem.
The attached code TestPrint.m should help to repeat the problem.
