I came across a wonderful document on the Canon website for VISTA
downloads for a Canon printer I was asked about recently which
described in very clear detail how to set up a network enabled Canon
printer in VISTA. It was illustrated with screen shots and included the
two things I have seen stated elsewhere although I've no experience of
setting up a networked printer or all in one myself:
1 -- You have to make an installation on the VISTA "remote" PC of a
local printer
2 -- You have to set the port being used to a specific description, not
the old LPTn of course or even a DOT4 ....
Here's a link to the pdf file of instructions -- download it and see if
it helps:
