No, the percent character is not a wildcard. It indicates that what 
follows is a regular expression. Yours matches any host _containing_ 
"_ip_printer"

HOST=%foo.

Would match any host containing "foo" followed by any other character. 
That gets close to what you want in the fewest characters. But it will 
match "food" just as well as "shesafool" or "ofoo8".

HOST=%^foo.

requires that the host name begin with "foo" and is followed by any 
character. This would match "food", and "foo8".

host=%^foo\d

requires the hostname begins with "foo" and is followed by a digit.
