the ip logo on line 1 occupied at least 43 bytes, depending on the number of control characters, so the space available for the ip's data is 877 characters at most. lines could either occupy the full forty character positions, or be terminated early with a cr/lf sequence. each control character took up two bytes, despite displaying as a single space, so the more complex a page, the less actual information could be presented. it was almost impossible, therefore, to display a right hand border to a page.
