Re: P2055dn Can't Stop Duplex Printing

We had the same problem with the PCL6 driver for a 2055dn. We updated to the 20120615 firmware. That SOLVED the problem for us.
HP could be a tad more descriptive in their firmware Enhancements or README notes. The note that caught our attention was:

"Changed media selection algorithm so that type has precedence over duplexing"

SO what...type is that?
