QSL card on 9x14

[F6DKQ]

I'm digging up an old topic....   anyway I just put my question here :

Is there a model to allow to print on 100 x 15 mm bristol cards
On my Brother Laser printer, I can only put the cards in portrait orientation , narrow side in front

I've tried all the models, including 9x4 ones, all combinations of printer properties on my computer
and on my printer itself (paper settings) nothing works  ......A4/A6      portrait/landscape....

Any help would be appreciated.
