IPDS Stream File and Duplexing

80 pts.
AS/400 printing

I am including the duplex option and adjusting the Medium Copy Count and the Medium Modification Control to reflect duplexing in the stream file. I must be missing something, when the spoolfile prints, the printer sounds like it is duplexing, but does not print on the back of the form. The next record is printed on a new page. Does anyone have any ideas?

What happens when you specify duplex *NO ?

That is odd – with the print file or override set to:
-duplex(*no) you get pages printed properly – no blank pages
-duplex(*yes) you get apparent page reversal but no printing on back!

did you have a back overlay? try making it blank or the same overlay as the front.
Can you print duplex ever? — say from Word? —

Are you telling the printer to duplex with that string and also changing or overwriting the print file to duplex?
If your printer is defined properly, I don’t see why you need to make any other changes then duplex(*yes).
By doing both ??? My experience with IPDS printers only needed the duplex(*yes).

Thanks for the feedback – I suspected the program but once it printed correctly without duplex I failed to consider that it might be closing and reopening the spool file. So you should have generated a lot of spool files? Silly of me – I had a similiar case with invoicing, back about 95 — wasn’t messing up the duplexing but was downloading the overlays for each invoice — what a hog.

    Prints fine. The printer does not attempt to duplex.

    I can duplex on any other type of document. Here is the Medium copy count that I am defining: X'5A0014D3A288000007000100010002000100010002' Which, according to my understanding creates 2 subgroups, each defining 1 copy and mapping to the Medium Modification ID 0002 The Medium Modification looks like this: X'5A0014D3A78800000802FFD100E002E101F402F856' Which tells it to duplex.

    The problem turns out to be code that was ending the document after every page. Once I put in logic to control the begin/end commands, it printed fine. I did attempt to remove the duplexing from the stream, but that did not work because the file is defined as form definition *INLINE, so it still did not print correctly. Thanks for all your help!
