I am using a program of impression(printing) of etiquettes, these have a size of 100 * 152 mm, if I stamp on an A4 the etiquette it(he,she) goes out for me with the size on that I comment previously, but if I use an etiquette with these measures what does me is to stamp on limited(small) size the etiquette, that is to say as if it was 4 times mas small. There is some option in 2x universal printing that does an autosize of the leaf(sheet)
the universal printer only produces what it is sent, ie if a A5 is sent to it thats what it will create, then the local pritner is responsible for printing it out using its own driver options
