Samsung CLX-3160FN network printer On 10.04 this same printer did and still does print duplex just fine. The print dialog shows the option for duplex printing and selecting it shows the normal 3 options. When I select print the printer acts like it is going to print. The light flashes and the led says printing but nothing happens. It stays that way until I turn it off and on. I tried to print a pdf and a text file from gedit with the same results. If I look at it with the browser interface it shows that the job has completed. Also the driver it is using is exactly the same version that was used in 10.04. Googling and looking on launchpad shows some duplex problems but nothing that seems to match what I am seeing. It's been 2+ years since I setup 10.04 and I don't remember having to do anything special to get it to work on 10.04. Having said that, my memory is not what it used to be, so before I file a bug I thought I would check here. Does anyone know if I should be doing anything beyond the basic install to get duplex printing to work? Thanks, Jim </blockquote> Don't have the same brand of printer, but to get printing to work properly on one of my hp printers I had to change to a different driver one that was CUPS+gutenprint instead of straight CUPS, in you have multiple choices you might see if changing the print driver solves the problem. In my case it would flash the printer light but fail to print from specific applications and also showed that printing had completed. Linda --</blockquote><div>I ditto Linda. Had to change my driver as well to enable duplex. In addition you have to be sure that if the printer itself has a switch or a setting that enables/disables duplex, then be sure it is enabled. </div></div>
