SuperLaserSpool makes a copy of the Deskwriter driver so that it doesn't interfere with any other application which may access the driver while the spooler is working.
The problem is…SLS views both the normal and the Greyscale drivers as being the same thing, so it will not bother to make a copy of your new Greyscale driver. Results: the grayscale looks the same as usual because SLS didn't switch the drivers even though you did using the Chooser. If you temporarily disable SLS, you will see that everything is working just fine.
Solution #1: Use HP's spooler. It's faster, friendlier and it's free.
Solution #2: Use SLS's SetUp function to disable either the Greyscale driver or the standard driver (you decide which one you will use the least.) Only one driver can be active for spooling. For HP color driver 3.0 and BW driver 3.9, SuperLaserSpool has trouble even seeing your extra new drivers in the SetUp.
Solution #3: Order the latest release of SLS and hope they fixed the problem. (From what I hear, this problem is a bug in their software but I have not spoken personally to the publishers directly.)
Solution #4: Especially when memory and disk space is limited, make one Greyscale driver, trash the original (in the System Folder and/or Extensions Folder) and the SLS 3.0 copy (with a name something like “SLS -> DeskWriter” ) located in the SuperLaserSpool Folder within the System Folder. (Note: versions of SLS prior to 3.0 don't use an SLS Folder.)
With only one Deskwriter driver to deal with, SuperLaserSpool will be happy as a clam and you will get great grayscales. Most of the time you will only want to use just one driver. Pick your favorite with SLS off and then trash all but your favorite. (Don't forget that SLS copy!)
Personally, I use SLS all the time because I am always switching printers and it is so flexible. It is set for all printers except the Deskwriter printers. I also have HP's spooler running for when I'm printing with the Deskwriter. If you have the extra memory to run both, you'll do just fine.
SuperLaserSpool does not interfere with HP's Print Spooler so your HP printer(s) can be spooled with HP's spoolers while any laser printers, impact printers or whatever can be spooled by SuperLaserSpool.
