[otrs] Ticket article order when printing

Hello, I've successfully changed the article sort order in a ticket with Ticket::Frontend::ZoomExpandSort (reverse), but when printing (PDF or normal), the order is the opposite. Anyone have an idea which flag I can use to change the print order articles in a ticket? I've been searching in vain. Also, is there an easy way to change the default background colour of the printed ticket/article when using PDF? The default is a gray bg, which makes it difficult to fax. Thanks Henry
