Thanks for sending me the data so that we could check out the performance here.

After I deleted the hidden columns from the converted specification, printing out the complete set of statements for 33 departements took 7 seconds to generate the print job and a total of 1.25 minutes to complete on our HP8000 printer. This was printed off my local hard disk, not over our network. Over our 100Mbit network, the generation time went to 12 seconds. (I didn't bother printing out the set again.)

I've e-mailed you the specification I used.
