        I do.  Saved in a backup before I did the jessie install.

  	<LOL>  I deconfirm this!  I have run a sequence of error-testing
	which has wound me up with a file that says my problem is:
	I don't have pstoufr2cpca.

         Good question.  I don't know.  When I installed wheezy, back
	 in 2014, I had printing difficulty at the beginning then, but
	 got it cleared up by getting in touch with people at Canon.
	 I can't remember how.  Unfortunately I never thought to back up
	 /usr/lib/cups/filter/

	! !  Yes.  I thank you for this.  I had found a similar
	file which purported to give me  pstoufr2cpca , but it
	was in Chinese.  ! !  I was going to post asking for a
	Chinese reader for help, when your instructions from
	Australia came in.

        Have done.  And I now have a file
-rwxr-xr-x 1 root root 33724 Apr 11 19:57 pstoufr2cpca*
        nicely ensconced in my /usr/lib/cups/filter  directory.

So I tried printing a four-line text file and got the response;
    Error - scheduler not responding.

This happens even after re-booting.  So I still need help . . .
Aaaarrgh!  What is maddening is:  When I want to scan an image
with this elegant piece of equipment, I get gorgeous results.  But
somehow the basic facility of printing isn't working.

I repeat:  it worked like a charm under  wheezy.

I hope that some expert knows how to set, or reset, the scheduler!

TIA for anticipated help!
