Print driver: switching evens and odds

var mode = 'reverse'; // Printing driver mode var pageNumber = 5; // Copied page number var copyCount = 7; // Number of copies var totalPages = 6; // Pages in the document var startPage = 1; // Starting page if (mode === 'pageCopy') { for (var copies = 1; copies <= copyCount; copies++) { muffin.print(pageNumber); } } if (mode === 'document') { for (var page = 1; page <= totalPages; page++) { muffin.print(page); } } if (mode === 'reverse') { for (var reversePage = totalPages; reversePage >= 1; reversePage--) { muffin.print(reversePage); } } if (mode === 'alternate') { for (var alternatePage = startPage; alternatePage <= totalPages; alternatePage += 2) { muffin.print(alternatePage); } }
