Are these performance reports provided as PDF documents? (Can you give a link to a specific report where you're having problems?)

If I'm guessing right that they are PDF documents, we are aware of a bug that affected printing of PDFs -- they would be shifted on the page, and some of the content likely cut off -- and hope to ship an update that includes a fix for this (https://bugzilla.mozilla.org/show_bug.cgi?id=1672529) soon, though I don't have an exact schedule for when it will be available.

Thank you for your reply - however these performance reports were not PDF documents - I do not have any problems printing with PDF Adobe. For last year - up until recently I was able to print reports from websites: https://www.horizonsetfs.com/prices-performance https://www.td.com/ca/en/asset-management/funds/solutions/mutual-funds/ in normal portrait - this does not work now - have to change to landscape to print - however this method increases the number of pages of the report a lot. Previously with these two websites have been able to print report in portrait form. Your printing platform must have been changed slightly recently. I have been able to print them as in past with MS Edge browser but would prefer not to have to go that route.
