How can I print form data in a standard letter

I have a Access2002sp3 database. Data is input via a form into a table and
sometimes (at the time of input) we need to print the data out in a standard
letter format (basically like a mail merge with a standard letter template
and data coming from the single record in the table). So far we've been
doing it by exporting the whole table to Excel and then doing a mail merge
selecting only the records that we want printed. Very tedious !!! Is there
some way I can put the standard letter into an Access report and then just
click on a control button on the input form to print the particular record's
data in the standard letter ?

thanks
