Notice that such a function is usually located in the printers (or, more precisely, the printer queues) backend and you are - by trying to do what you do - second-guessing the work of it. Chances are this might get filtered out in the processing the printer driver does after you send it to the queue.
Some historical background on where that mattered: you probably know that the line-feed sequence in UNIX is a "linefeed" character, whereas in DOS/Windoze it is a carriage-return plus a linefeed. The reason is: (dot-matrix) printers worked this way, the carriage-return moved the printing head back to the left side and the linefeed move the paper upwards. It was quite like the mechanical and electrical typewriters that preceeded printers. By having this sequence as a end-of-line sequence the makers of DOS could forego the necessity to write a printer driver for their OS. UNIX, on the other hand, had printer drivers and therefore didn't need a two-character sequence. Therefore it had (and has, up to this day) a one-character EOL sequence which is in turn changed to a CR+LF if you print something to one of these old dot-matrix printers with endless paper.
Now, consider what that would do to your print job if you would mess around with the EOL sequence yourself: most probably not what you wanted to have because between your artificially inserted characters and them being processed (and turned into something maybe completely different) by the driver the printer might get confused over the result.
My suggestion is: use a "high-level" document language (i.e. Postscript, TeX, PDF, ....) to create your report. You can easily force form-feeds (or, repectively, their equivalent) within these languages because the all have that. Then use a driver for the respective language (in fact there are even natively-capable Postscript printers) to process your generated file into a correct print job. This way you are save from unknown (and unwanted) side effects and furthermore you are not bound to a specific printer model. All the mentioned languages are quasi-standards and you can easily swap one i.e. Postscript-capable printer for another Postscript-capable printer and the printed result will guaranteed to look the same.
I hope this helps.

Hi,
I've a text file that has a formfeed character at the beginning.
I want to get rid of this formfeed character using sed.
But I don't know how to specify the formfeed character.
I've tried \014 (octal for formfeed), \f but still not works.
