Black vertical line in Trello card print preview — rendering bug?

[Michał Rożnowiecki]

Hi,

Since a few months ago, when printing a Trello card using the “Share → Print” function, a black vertical line appears on the left side of the printout. This happens consistently across multiple browsers (Edge, Chrome) and also when saving to PDF or XPS.

The card content is correct — description, activity log, etc. — but the visual artifact makes the printout look unprofessional, especially when sharing with clients.

I’ve tested this on multiple machines and confirmed it started after a recent Edge update, but Chrome shows the same behavior.

Screenshot attached for reference.

Is this a known issue? Are there any workarounds or plans to fix it?

Thanks in advance!

Hi Michal, welcome to the community!

Usually, that happens when the background is set to print. When you go to Share > Print on your card, check if the option "background graphics" under more settings is checked. That's for Chrome, but in other browsers, there should be a similar option related to printing the background. Try to uncheck that and see how it goes.

Hope that helps! Any questions let us know!

Thanks, Luciana — disabling “background graphics” does remove the black stripe, confirmed in both Chrome and Edge.

However, this reveals another issue: the Trello card layout in print preview isn’t aligned to the left edge of the page. Text fields (description, comments, activity) are offset, which causes a horizontal scrollbar and makes the printout less clean and professional. You can see this in the attached screenshot.

Is there any plan to fix the layout rendering in print mode? Or maybe a way to force left alignment (via CSS override or URL parameter)?

Thanks in advance — I’m preparing clean documentation for service records and would love to streamline the output.

Best regards, Michał

Hi Michal! Glad that the background setting helped you! Regarding your other question, I'm afraid there isn't a way to force the alignment at the moment. So I have opened a suggestion to our Product/Dev team for consideration that you can check here: https://jira.atlassian.com/browse/TRELLO-1545

I have also added this post as an internal comment to this report so that way our engineering team can reference it and also use it to help align priority.
