Clay, Thanks for the suggesions. A number of years ago I would have expected the slow times. But I can print other PDFs print quite quickly (a few seconds per page). The the tables in them are not quite as intense as these, but they still do have tables. And the printer visibly slows down on some pages (graphics and complex pages). But both Postscript and PCL6 take a long time to print a single page on the Laserjet 2100. The inkjet (6211i) has completed the page within 10 to 15 seconds. Very fast compared to the 2+ minutes for the Postscript Laserjet driver and about 3 minutes for the PCL6 Laserjet driver. YES, I was amazed the inkjet complete the job before the Laserjet 2100 had really even started thinking about it. When I first saw that the Postscript print job was about 1/5 the size of the PCL6 print job, I was hopeful - but it still took a long time to print (more than 2 minutes). I've tried a number of setting changes - (reduced quality, faster printing, save toner, etc.) but not luck. I guess I was thinking that there might be some FOP initializations to use; or maybe guidelines on certain FO statements to avoid if possible (obviously the fewer the better :). Bingo! Just got to thinking. Although the Laserjet is connected via a 100mbs Ethernet printer server, I seem to remember (it's a Netgear) that the buffer was quite small in it. I'll hook it up directly and see if that makes a difference.
