codice:

// Get the FontMetrics for the current Font

// If a new page is beginning shift the cursor in the bottom position of the first row
if (currY == 0) currY = rowHeight;
// Tokenize the test to be printed in row

// Remember is the last row printed is empty or not

} else {
// the row isn't empty

// split the current block of text in more row to fit it in the page

Guarda questo codice,forse non fa perfettamente al caso tuo ma può darti qualche idea su come la cosa possa essere fatta.
