Slowdown when printing to PDF in a loop

[Terry Judd]

Hi Craig - yes, I open and close printing for each report. I might be wrong (I’ve been using variations of the same printing routine for ages) but I seem to recall that I was unable to successfully or reliably create separate reports unless I closed printing after each one.

While it might start off printing say 14 reports per minute after a few minutes it's down to only 2 or 3. When you're printing 350 reports that obviously takes some time. I'm wondering whether there is something I can try to 'clear the pipes' every few minutes to speed the process up a bit? I've had some success in the past splitting the data up into batches and looping through one batch at a time but it would be great (or at least simpler) not having to do that.
