You might also test this with Save As PDF in place of print. That exercises much of the same code as Printing but since it does not send print jobs to your Fuji printer driver, that may reveal useful details and may show whether or not a different printer or printer driver version would have the same issue.
Thank you for the suggestion PhilModJunk. I tested exporting to PDF today and there was no increase in memory usage or high CPU usage that I have when using FujiXerox printers. I also managed to test the printing on an Oki C5800 printer and also there were no memory problems ther either. The problem seems to be with these printers by FujiXerox. We have 3 wildly different FujiXerox printers of different ages and models so I did not think it was becasue of the printers. Also the problem still does not happen on older versions of FileMaker with the same drivers. I normally use Apple distributed FujiXerox Drivers but I tried manufacturer's latest drivers. Still had the same problems though. I tried printing with different applications and it's only FileMaker 11 (so far) with this problem.
Since the high memory usage (which imitates a memory leak) is in FileMaker 11, could the problem reside there despite only happening with these brand of printers? Thank you for you help.
The fact that Save as PDF and printing to the Okidata printer does not show this behavior is a pretty strong indicator that there is a printer driver specific issue, but there is no way to tell for sure. One long shot to try is to visit the fuji web site and look for any updated printer drivers to download and see if it creates an issue.
And yes, it is entirely possible for one version of FileMaker to have an issue with a specific printer driver and not others.
