4. Click on document background to deselect any objects

Can you print to file?

Can you print to file?

I can't get far enough to select that option - program locks up immediately after print dialog pops up. This is still happening after upgrades through 24.4.0.

I can't repeat this. I'll leave it open, but unless someone with the right environment can repeat and wants to investigate, it's very unlikely to be looked at.

[jonathanhirschman]

I can investigate :smile:

I uninstalled the deb package previously installed: $ sudo dpkg -P draw.io

I reinstalled: $ sudo dpkg -i ./drawio-amd64-24.4.13.deb

Running the app from the command line: $ drawio Checking for beta autoupdate feature for deb/rpm distributions Found package-type: deb

Then placed a shape and attempted to print to PDF: Crashing due to FD ownership violation: #0 0x59076d8e8b03 <unknown> #1 0x59076d8e0c0c <unknown> #2 0x59076d8e0bc7 close #3 0x7d49d4694ef3 <unknown>

FYI. I have some print functionality from the community flatpak version, but it's old. Snap version doesn't see printers at all.

I did some more research. The issue is related to Electron and networked printers (which is what I use): https://github.com/electron/electron/issues/31151

FYI, and probably explains why you cannot reproduce.

Thanks for the research, it does indeed look like https://github.com/electron/electron/issues/31151.
