This shorter nawk trick should also work:

Code:
BEGIN{ FS=OFS="="}
/^#|^$/ {print; print > "/tmp/new_config"}
!/^#|^$/ {
	print "Set "$1 " - actual  (" $2 "):"
	"read value; echo $value" | getline myvalue
	print  $1,myvalue > "/tmp/new_config"
	close("read value; echo $value")
}

NAME
lpdomatic - Foomatic filter script for LPD, LPRng, and GNUlpr SYNOPSIS
lpdomatic [OPTION]... <PPD-filename> DESCRIPTION
The lpdomatic print filter serves as an input filter for the lp family of print spoolers. The print spooler will use it if there is an entry if=/usr/sbin/lpdomatic in the appropriate printer section in /etc/printcap. You can generate such an entry using foomatic-configure. A listing of the attached printer drivers options is printed, when the option docs is passed to this filter. This can be achieved by issu- ing one of the following commands: for LPRng use echo | lpr -Z docs for other spoolers echo | lpr -J docs Options -j option (all but LPRng) Pass option to the printer driver. May also be read from the environment. -J jobtitle (LPRng only) Set the job title to jobtitle. This may be used to set a title header when printing plain text. -Z option (LPRng only) Pass option to the printer driver. SEE ALSO
