This is my first post so please be gentle.
I have searched the forums, but I can't seem to find the exact issue I have. I am running the latest version of Zimbra open source on Ubuntu 10.04LTS. I apologise if this has been asked previously.
My problem is best explained by the two attachments with this post. The email screen view is formatted correctly, but for some reason when printing, it changes to a proportional font instead of a mono-spaced font. I thought at first it was how we were generating emails with another application. Our company application generates HTML formatted emails, and uses IMAP commands to save them in the user's drafts folder for editing and sending.
However, as you can see from the attachments, its not our custom app, it is also happening to the Zimbra admin emails.
I have tried using Chrome, Firefox and IE, all latest versions running on Windows 7. We are using Kyocera printers with the latest drivers.
