how to print on every line of the page, from 1 to 66?

The following code blows up when printing on the 66th line on the page.
Overflow is set to 66. How can I write printer code that prints on each
line of the page?

( I am printing CSV formatted data, then emailing the spooled file. If the
page does not have all 66 lines filled, I get gaps in the resulting
spreadsheet. )
