Thanks, everyone, for your contributions which have been most useful in
helping me to cross-check everything.

However I have done experiments with Windows 8 (both 32-bit and 64-bit)
on different computers and this is what I have found:

(a) Photos will print from computers using 32-bit with no apparent
problems

(b) Photos will *not* print from computers using 64-bit. However I must
qualify that. On just *one* occasion, I did manage to get a photo to
print from a 64-bit computer. I used the Windows Photo app. and then the
print dialogue in the charms bar. But, when I tried to repeat it, it
wouldn't work.

Did I install the 64-bit version of the HP driver? Yes! Or, at least, I
installed what I downloaded from HP when I requested the driver for
64-bit.

Nevertheless printing small files is still no problem.

So I am inclined to believe that there is a flaw in the HP driver for
64-bit. Could it be a memory allocation problem?

Incidentally I didn't mention what printer I was using. It is a
Photosmart 2610. All the other functions, including scanning, seem to
work ok. Yesterday I tried once to print from a 64-bit computer to a
Photosmart 8750. It printed but the colour rendering was all wrong.
Haven't had time to worry further about that one!


Almost sounds like a problem with printer spool space. I have zero
knowledge of the workings of Win8. One possible way to see is spool
space is an issue in older Wins is to not let Win manage virtual
memory and set a specific amount so that you know there is adequate
disk space for the spooler.
