No problem,
With a code that is going to automatically print out 29+ reports you will want to tap through it with F8 while you see how and if it works.
Give this a try and let us know how it works.
Code:
Option Explicit
Sub ChangeNameThenPrint()
Dim wb As Workbook, cws As Worksheet, nws As Worksheet
Dim CheckRow As Integer, TotalNames As Integer
Set wb = ThisWorkbook
Set cws = wb.Worksheets("Certificate")
Set nws = wb.Worksheets("Names")
TotalNames = nws.Range("A50000").End(xlUp).Row
For CheckRow = 1 To TotalNames
cws.Range("B42").Value = nws.Range("A" & CheckRow).Value
cws.PrintOut 'You can set specific printer properties with a ( after Printout
Next CheckRow
End Sub
