since the 6.0 update, when hitting “print report” my Tryton immediately prints reports instead of creating odt files first which then can then be printed. Can I revert to the old behaviour? - Normally I do not fasify my invoices, but making small changes are essential to my workflow.
I guess you are using the print option instead of the open report.
Prior to 6.0 series, the behaviour was the same for both buttons on linux, because we missed the direct print support. On 6.0 this functionality has been added, so you should switch to the “open report” button if you do not want to print it directly.
