There is still a mistake I guess.

Thanks for helping, but please deal with it not today anymore. "Lets call it a day".

Noticed the issue with what I typed (sorry not a the computer right now). Type this instead, at the same location:

(service cups-service-type
(cups-configuration
(web-interface? #t)
(extensions (list cups-filters hplip))))

I added a closing parenthesis on the first line that shouldn't be here, and I forgot to wrap the value of the extensions (now it's a proper list instead of three values which is an error). Also check that the last closing parenthesis at the end of the fourth line closes the first one on the first line and you should be good!

            They're used to group things together. service,

                    Your service specification is not at the right
                    place, and incorrect. You have to be careful with
                    parenthesis, as they define the structure of
                    things (similar to braces in other programming
                    languages). The service specification needs to be
                    inside the list, at the same level as all these
                    (service …) forms. In the same way, you declare a
                    service with (service foo-service-type
                    <configuration>), and the configuration is usually
                    a record, so it has parenthesis too. For records,
                    you do: (<record-name> (<field-name>
                    <field-value>) …) With as many fields as you want,
                    as long as they exist. In your config, guix found
                    (cups-service-type) at the same level as other
                    fields of the operating-system, but
                    operating-system doesn't support such a field
                    directly, and the field does not have a value.
                    Overall, try something like this, at the same
