we are sending a string to a lpr using
FILE *prn = popen ( "lpr","w");
finally we do a pclose()
this routine get called for some asynchronous event.
the problem is that after every close or new open ( i dont know ) the lpr
gives a page feed ( or form feed ) and runs to the next page.
now the stuff we are printing is 5 lines long i dont want the whole page to
go waste.. how do i stop this from happening.
i tried keeping FILE *ptr as extern but it does not work
( should it work, ?? )
HELP !!!

Isn't this as simple as popen()'ing only once and repeatedly
writing to it? Perhaps you need to fflush() every time.

has the lpr daemon been set up for "send Linefeed after each job" or some
similar settings???
well i am not sure where this option is....you may just try to run the
program with lpr disabled or try to take a peak into lpr settings.
