I have the Samsung ML-2950 mono laser printer that has double sided printing. Never had problems printing such mode, when needed. This past week, with IRS time, it usually came in handy to make such printing. When I set it up, the paper comes out double sided, but on only one side. Never had that before. I thought maybe driver got corrupted so with the same disk that came with it, I reinstalled everything. When I tried again, this time I got what i wanted. A few minutes later i tried again and this time it reverted to the side by side on one page again. I have no idea why this is happening. In properties, I pick double sided, short paper as I always had. User manual does not say anything on how to set it up. I found out that Samsung sent all its printing support to HP, who in turn sent me to someone in the U.K. Needless to say, he wanted to take control of my pc and set it all up for a rediculous price. I hung up. The printer is working just fine, with the exception of double siding...its not reliable anymore. Anyone here has such a printer?
