Need Help with PCL duplex

[klamerus]

Help.

We have an application we've created that generates PCL documents. We do this using the Adobe PDF libraries. We are turning PDF into PCL with those.

We have duplex printers and need to print in duplex or simplex as we choose (as the users choose). They automatically come out in simplex, so we really need to direct the printer to do the duplex (and also later how to tumble the duplex). We've created a program that adds the statement @PJL SET DUPLEX=ON, but it seems to be ignoring this. We're concerned that there are escape codes following the PJL that are re-setting this back to simplex.

We're hoping that someone can confirm this is the right statement and knows enough about PCL to look at one of these documents (we could mail since the file is just < 2 MB) and tell us why it's not printing in duplex on a standard HPLJ5 printer. The printer is fine and does duplex when printed to directly from desktop applications (where we choose this option). It's got to be something in the content, but the content does come out right, so the PCL is valid.

We might even pay (via pay pal) for someone who can identify the issue and provide a solution, if that's what it'll take.

Your PJL command probably doesn't work because there is an explicit simplex command in the PCL.

I would have to look at the code to confirm.

Thanks. Document sent in zip.

We suspect that is it, but need help for 3 thing:

1, to confirm that the command provided should work
2, to help find what may be overriding this
3, is there a better approach to this issue

I would need a much better understanding of the entire process being used to advise. The only thing I can think of offhand is that the printer driver is not aware of the duplexor.
