Hola, Casablancas. ¡Bienvenido al foro!
A continuación está una complicada definición en inglés que encontré.
"A printing apparatus which can feed sheets of paper of a plurality of sizes, including at least first, second and third paper sizes, wherein a paper of the first paper size can be fed in any of long-edge feeding and short-edge feeding directions, said printing apparatus comprising: reception means forreceiving, from an external apparatus, papermixture information indicating that a plurality of paper sizes exist in mixture in one print job; determination means for determining whether a paper of the first paper size is to be fed in the long-edge feeding direction or in the short-edge feeding direction, based on the paper mixture information received by said reception means; and output control means for producing a printing product which aligns the long edge of the first paper size and one edge of the second paper size, if said determination means determines that a paper of the first paper size is to be fed in the long-edge feeding direction, and producing a printing product which aligns the short edge of the first paper size and one edge of the third paper size, if said determination means determines that a paper of the first paper size is to be fed in the short-edge feeding direction."
Creo que en español se le podría decir: Impresora con capacidad de impresión de hojas de diferentes tamaños y posiciones.
Saludos.
