Usually, the number of lines that can fit on a page is determined by the physical length of the page, the size of the margins and the height of the printer font.
At times, files are pre-formatted to a particular page length (usually around 60 lines). That is, the file usually contains it's own header and/or footer every 60 lines. Printing a file which has been pre-formatted to 60 lines on a page that is physically 66 lines long will look awkward - headers and footers will start appearing all over the pages, instead of where they should be!
To overcome this problem, you can override the physical page length by specifying the length of the printer page. This causes V to start a new page as soon as the specified number of lines has been printed instead of waiting until the end of the page.
•The page length specified must be less than or equal to the maximum page length allowed by the printer.
•Pre-formatted files usually contain their own header/footer, so you will probably have to disable V printing any of its own.
•If your listing is already formatted to a certain page length which is larger than your printer page length, you will have to increase the size of the printer page (by reducing the top and bottom margins and/or disabling the header/footer) or reduce the size of the printer font.
•Some files contain form feed characters (Ctrl-L or ASCII 12 decimal) to indicate a page break. V will start a new page whenever it encounters a form feed.
