Create a Page Summary band (it can be a zero height) and call a UDF in the On Exit option. In the UDF, do something like:

LOCAL lcAlias
lcAlias = ALIAS()
SELECT InvoiceHeader
REPLACE PrintCount WITH PrintCount + 1
SELECT (lcAlias)

If you only want to increment the count when the user "Prints" and not when they "preview", change the code as follows:

IF WEXIST('Printing...')
  LOCAL lcAlias
  lcAlias = ALIAS()
  SELECT InvoiceHeader
  REPLACE PrintCount WITH PrintCount + 1
  SELECT (lcAlias)
ENDIF

Hope this helps,
