how can i 'flag' a record to a field at the same record that have we print that record?

example:
name | printeds
---------------
ari | 'F'
henry| 'F'

if we already print record 1 and yet record 2, so the table change into:
name | printeds
---------------
ari | 'T'
henry| 'F'

if we already print record 1, so we can't print record 1, just record 2,
after we print record 2, the table change into:
name | printeds
---------------
ari | 'T'
henry| 'T'
