Print processor problems Brother MFC-J6910DW reverse order printing

OK, I'm using Windows 7 on a 64 bit quad core Asus PC in my part time business home office here.

About a year ago, I bought a Brother MFC-J6910DW multifunction. It was apparently poorly designed, because it printed in "reverse order", right out of the box. What this means is that, if I print a 100 page document, it will print the stack out with page 1 on the BOTTOM and page 100 on top, and if I want it in correct order ( of all my NERVE ) I'd have to hand sort it in reverse. YES, this seems INSANE but this is how they designed this printer!

The only "work around", I was told by support, was to set it to print in "reverse order", so that page 1 would come out at the top of the 100 pages. I kid you not, folks! So I did it, it sort of solved the problem, but was very slow at printing large files ( over about 40 pages ) because it apparently had to process them in reverse order in the Windows print spooler, then print them? So this went on until last week, when something went wrong in the scanner software and it could no longer communicate ( using this via wifi ) with my PC. So I had to uninstall the huge software app, and reinstall it again. I set the "reverse order" setting in the devices and printers settings, as the default, being I knew painfully about it, this time.

SO today, I had a rush project and had to print a file that was 42 pages. I started around 10 AM and was supposed to go out with the work around 1 PM. I needed 6 sets, but being I'd just installed the software again this week, I figured I'd try one set first.

So it was processing for around 25 minutes, and still not printing. I decided to watch it, and canceled the job and tried again. It only took about 6 minutes to actually process the pages, but as it went from 41 to 42 in the spooler window, it showed an error. Then it restarted all over again. So this would have gone on forever. I called their support, got hung up on by the first person, called back, was on hold for another 15 minutes, then the guy, who apparently didn't speak English as his native language, spent 20 minutes running me through menus and settings, and finally proclaimed that it was a "print processor" problem in my Windows OS and I should take it up with my PC manufacturer! This, after I've been through 4-5 different printers since buying this PC and never had the problem, until I had to "reverse order" print because of their stupid design! And I realize that he told me this, because that's what people do when they have no idea how to solve a problem.

Nearly in tears by this point, I finally had to take the PDF file over to Fedex Office and pay them $32 to print me the 6 sets I needed, to keep my client happy. I was disgusted.

But now I'm back home and recalled some of the menus he had me poking around in, and one of them mentioned the system print processor. Here's the first one:



and the Print Processor one within:




I don't know anything about the settings in there, but is it possible that my print spooler in Windows needs more memory or something and is running out, when processing so many pages into reverse order printing, or maybe one of these settings has something to do with it, in this menu?

Is anyone reading this?
