Thanks to all who offered help! 10.e recognizes and installs printer and scanner in the Canon PIXMA MP830, so all seems ok, for now.

The plea for help is a sort of double dip on this forum.  I also posted
a request for help with a driver for the Canon Pixma MP830.  After
sending that note, I tried to fix the problem myself by changing the
parallel port connection provided in the SUSE-supplied driver with a USB
port designation.
In short you connected printer using USB instead of parallel port cable.
The Canon PIXMA MP 830 connects to the computer by a USB port.

It wouldn 't accept it, saying that the port wasn't
properly configured!
I would need more details on this, like this:
  Printer connected to computer and turned on.
  Started YaST > Hardware > Printer
Do you see printer in YaST list, or there is no nothing?
What message below list tells?
I downloaded a new driver from Gutenprint and then turned on Yast2 and
went to Hardware>Printer.  The printer was not spotted but I clicked
"Edit" and found its driver in the collection of drivers.  I loaded the
driver.  This time, there was no port designated, but I was told that
the wrong spooler was chosen. SO, I guess the spooler picks the port.
What now?  (I hope this is all solved in 10.3 which I might be getting
in a couple of months, depending on the status of my 10/3 order with SuSE)

...
For instance it would be
helpful to turn printer on and run:
  dmesg | tail -n10
I ran dmesg | tail -n10 and got:

usb 1-6.4: SerialNumber: 188C80
usb 1-6.4: configuration #1 chosen from 1 choice

OK. Computer is communicating with device but wrong driver jumps in. Printer is recognized as USB storage device.

to see what kernel is doing. Is registered any activity on USB port.
Then command:
  hwinfo --printer
I ran hwinfo --printer (as root) and saw:

Thanks again for your help.

Hmm...
I don't see any line starting with Driver. Probably because it is not configured. YaST Printer has problem to access printer because device is already in use as storage, but 'hwinfo --printer' can see device. I guess that we need someone that can clarify this. I expanded the subject line, to attract attention of openSUSE printer specialists.
