Hi, Printers that support duplex printing, can handle this. If you send files as separate print jobs and you want it to be printed on both sides, printers that support duplex printing, automatically print a blank page. If you want to print on both sides of the page manually, you should first print even pages, and then odd pages. In this way you will have no problem with blank pages, as the output will contain that output page.
Please see this quote from Adobe Reader 8 manual: "To print booklets, your printer must support either automatic or manual duplex printing (printing on both sides of the paper). Manual duplex printing requires two separate printing passes: one to print the front side, and another to print the back side. To find out whether your printer supports duplex printing, check the printer manual, contact the printer manufacturer, or click the Properties button in the Print dialog box and look for options that mention two-sided or duplex printing." So, I think you should solve this problem in the application that shows pdfs and prints them. If it's a custom application, it can use the printer's duplex printing feature. See this: http://www.adobeforums.com/webx/.3bbdbfb3 > Not possible with PDF at all (let alone iText). > Give your client 2 PDF files - one for double sided printing, one without. I'll leave inserting blank pages as an exercise to the reader :-) Generating two seperate PDFs is also a quick fix for this problem.
