Preferences Printing
NOTE that the printing of HTML format messages may be problematic if the message has too complex a structure for the viewer. In such cases, open the message in a browser (right-click in the message viewer and select Show Message in Browser) as browsers usually handle printing more conveniently and accurately.
HTML format messages were not originally intended for very complex layouts, but rather to provide some formatting options not available in plain-text format. Unfortunately some email messages reproduce Website pages (in particular advertising newsletters), and can defeat the viewer used in MailCOPA.
