Envelope sizes not available on V6.4.4.2

On my old laptop using version 4.3.5.2 I can select the envelop size to print. On my recently bought desk top with version 6.4.4.2 the envelope size options are not available (I want to use DL) It just gives a couple of user sizes and Japenese postcard!! Please help.

Got no version 6.4.4.2 any longer but for current 6.4.7 I cannot confirm that there is no DL Envelope

Maybe, you need to tick the box “Paper tray from Pinter settings” in Tools > Options > Writer > Print?
