Blank pages inserted during duplex printing

Question

I just installed an OfficeJet 4500 G510g on a 64-bit Windows 7 system and configured it using the network interface.  After having some initial installation problems I downloaded the latest Full Featured driver and was finally able to get everything (printer, fax, scanner) working okay.  Tonight I tried my first duplex printing job and found that the output has random blank pages inserted.  The first time I printed, I got page 1 on the front of the first page and the back was blank.  Page 2 was on the front of the second page, page 3 on the back of that page and so forth up to another blank page between pages 6 and 7.  After looking at the configuration to see if I had something set up incorrectly, I tried it again.  This time I got page 1 on the front of the first page, a blank page on the back, another blank page on the front of page 2 and from then on it was correct up through page 7.  I am an embedded software developer and the ability to print duplex listings is very important to me.  Unfortunately, at this point I have no idea what to try next.  Anyone have any ideas?
Thanks,
Dave

Hi,
I'm hoping for an answer to this problem also. Here's what I've found so far:
"I am printing statements on a double-sided stationary capable printer. To ensure that each new statement starts on a new physical piece of paper, I need to add a blank page if the previous statement had an odd number of page sides. How can I do this?
Place an invisible boilerplate line before the repeating frame that contains your data. Give it a Page Break before and anchor it to the repeating frame. Then write a format trigger that only prints the boilerplate object (and thus the page break) if it is an odd page number. "
I've tried this but it isn't working for me. I'm using this logic for printing the page:
v_page number;
begin
srw.get_page_num(v_page);
if mod(v_page,2)=0
then
return (FALSE); --if an even page don't print
else
return (TRUE); --if an odd page do print
end if;
end;
If you find an answer I'm hoping you'll share it with me. Thanks!
