You may be missing careful wording folks...
“We’ve been trialling a new IT printing system" - Presumably true
"a number of mistakes were unfortunately not picked up before this letter was dispatched.” - obviously true
However they don't actually say the IT system was responsible for the mistakes, although quite probably the mistakes were made as a result of changing to the new printing system, they just weren't made *by* the printing system...
