Error Code 88 with Pixma Pro9500, even when art margins are set correctly

Question

I'm getting error code 88 (from the CanonPro9500 series print monitor window) when attempting to print on an A3Plus art paper (Hahnemuehle William Turner), even though I have the paper size set correctly (in the Photoshop Print Dialog, Print Settings) to "Art A3+(Margin 35)". 
(Furthermore – though most of the following options probably have nothing to do with the problem, and are probably the correct or allowable settings anyway – I'm using Canon Color Matching; MediaType: "Fine Art Museum Etching"; Paper Source: Front Tray; PrintQuality: High; and am printing in color, not grayscale.  Color Options are all left set at zero.)
I’m printing from Photoshop CS5 Extended,Version 12.0 x64, using an iMac with MacOSX10.6.8.  The Canon Printer Driver is “Pro9500 Driver – CUPS Version10.51.2.0”, recently installed (or re-installed) just the other day when I wastrying to deal with this problem (I didn’t check the CUPS version beforereinstalling the driver, so I don’t know if this could be relevant).
(I also attempted to print by setting, in Paper Handling, "Scale to fit paper size", with Destination PaperSize set also to the suggested Art A3+ (Margin 35), although I never had to do this in the past, and so I don't suppose it matters. Still, this did not help.)
I had the same problem attempting to print on an A4 art paper, as one is supposed to do, using front loading and the paper size set to Art A4 (Margin 35), with Media Type set to "Fine Art PremiumMatte" (it was a matte art paper). No go; I got error 88.  Iwas able to print on the same sheet by setting "Matte Photo Paper"(while still using Front Loading), but this is not the media type one shoulduse for such a paper.
In the past few years I have printed 8-bit files, in both AdobeRGB and sRGB, on A4 and A3Plus art papers, in both color and grayscale, always using the art margin settings, without any such difficulties.  Typically I use Color Management by Printer, or “Canon Color Matching” (though I experimented with the use of dedicated paper profiles and Color Management by Photoshop).  Lately I’m trying to print 16-bit files, generally Photoshop PSD or TIFF, with a document profiles of sRGB, AdobeRGB, or ProPhotoRGB. Of course I tried several times to print from an 8-bit file, and once using Color Management by Photoshop, but got error 88 just the same.
Does anyone know how to resolve this problem?  Sure hope so!  Thanks in advance, AlienAl

Remember that  you can set all your paddings in a single setting for a div. It's like a clock, starting in the 12:00 oClock setting, going clock wise.
#myDiv     {
     padding:5px 0 5px 0;
You don't specify a unit with 0 so the above would be the same as:
#myDiv     {
     padding-top:5px;
     padding-right:0;
     padding-bottom:5px;
     padding-left:0;
It works with margins also, etc...
