You can find the available paper sizes via:

PrintService printService = PrintServiceLookup.lookupDefaultPrintService();
Media[] res = (Media[]) printService.getSupportedAttributeValues(Media.class, null, null);
for (Media media : res) {
    if (media instanceof MediaSizeName) {
        MediaSizeName msn = (MediaSizeName) media;
        MediaSize ms = MediaSize.getMediaSizeForName(msn);
        float width = ms.getX(MediaSize.INCH);
        float height = ms.getY(MediaSize.INCH);
        System.out.println(media + ": width = " + width + "; height = " + height);
    }
}

Once you've found the available MediaSizeName that most closely fits your paper size, simply add it in place of MediaSizeName.ISO_A7.
