Windows or excel application to print many addresses to word file

Hello, We need a easy and simple windows application or excel macro or something similar to do following: We have a excel document with many customer addresses. About 800 addresses. Eeach address has its own row and each row has several columns for example for first name, last name, street, postal code, city... And we also have a letter in a word document into which the addresses need to be inserted. Now we need a simple solution to choose some addresses and then the word document will be printed automatic. For example we will enter the row numbers of the excel file seperated by comma in a excel script or windows application and then the printing should start. Please tell us your idea and solution for this task. Thanks
