Hi Guys: I have a very similar problem. brand new Canon PIXMA MP600.... gone
through about 10 hours of techie consults with Canon and Dell... no dice!
keep getting "printer not responding" message . can't print from any thing:
Word , Notepad, system prompts, etc. The printer will print a test page
from installation package.
No problem showing on system menus re: USB ports. Also, have a Panasonic
Lumix which I can download via same USB ports with no problem so I don't
think the ports are damaged. Have installed/uninstalled/installed, gone back
to the store and been given another machine, same model. Obviously some sort
of snafu communicating between computer & printer.
After reviewing this forum it seems to me that there is some sort of glitch
in Windows that is affecting many of us with similar, if not the same
problems. Oh, I also installed Service Pk2 several months ago, have disabled
the firewalls, uninstalled REal Player, as suggested here and elsewhere on
this thread.
I sure appreciate all the ideas floated by folks on this site and would
welcome any and all suggestions! The last word from Dell ( Microsoft won't
talk to me as XP was installed by Dell when I bought the computer.) was to
send me to their "specialists" for $129. Not too happy with that idea,
especially when they wouldn't offer any redress if they couldn't help me
solve the problem. Thanks everyone.
