Technically, yes. You can manually flip your card over and print on the backside. Is this a good idea? Probably not. Single sided card printers were not designed for this type of use, and you run the risk of early print head failure or experiencing poor print quality. When running the card through twice you are exposing the print head to extra dust and debris, as well as the oils from your finger tips. Damage to a print head from non-standard use will void any warranty coverage.
Dual sided card printers have come down quite a bit in price in recent years; it really is not much more to add this feature. There are several printers on the market which can be field upgraded for dual sided card printing such as the Fargo DTC400e or the Fargo HDP5000 for secure applications. Manually flipping your cards over will cost you more in the long run with the cost of a replacement print head starting at about $500.
