There are multiple revisions of this printer, but the appropriate page is probably
http://support.brother.com/g/b/downloadlist.aspx?c=us_ot&lang=en&prod=dcp1512_us_eu&os=128

This one works with the Brother scanner driver "brscan3", judging from its Gentoo
package.  The DCP-195C isn't specifically listed on Brother's page that I can find, 
but this machine uses the same scanner driver:
http://support.brother.com/g/b/downloadlist.aspx?c=us_ot&lang=en&prod=dcp165c_all&os=128

You should be able to download .debs from those pages.  It might also be worth
trying setting up the DCP 1512's printer half as a generic Postcript printer, as
Brother's drivers don't always work well with current versions of CUPS.  The
scanner drivers were OK for me, though.
