I can't replicate the behaviour you describe. In your new input sample, $24 is NOT empty in any line. $24 already HAS the difference between $2 and $25. And, as said before, with multiple spaces as field separators, you can't detect empty fields.
I'm afraid I can't help.

pbm2ppa
pnm2ppa(5 Feb 2000) pnm2ppa(5 Feb 2000)
NAME
pbm2ppa - convert portable bitmap (PBM) to HP's Printing Performance Architecture (PPA) file format
SYNOPSIS
pbm2ppa [options] [ <infile] > [ <outfile]> ] ]
DESCRIPTION
Reads portable bitmap (PBM) format as input. Outputs a stream suitable for processing by Hewlett-Packard's range of Printing Performance
Architecture (PPA) printers. pnm2ppa supports the HP 710c, 712c, 720c, 722c, 820c, and 1000c series printers.
(Portable bitmap (PBM) format output can be produced from PostScript(tm) input by the GhostScript driver "pbmraw".)
OPTIONS
infile Input file infile is either a path to a file or device, or '-' to indicate stdin (defaults to stdin)
outfile
Output file outfile is either a path to a file or device, or '-' to indicate stdout (defaults to stdout)
-b bottommargin
Sets the bottom margin bottommargin in units of 1/600 inches (e.g., -b 150 = 0.25")
-d Displays the current configuration
-f configfile
Overrides reading the configuration from /etc/pnm2ppa.conf, and uses configfile instead.
-h Displays program usage
-l leftmargin
Sets the left margin leftmargin in units of 1/600 inches (e.g., -l 150 = 0.25")
-r rightmargin
Sets the right margin rightmargin in units of 1/600 inches (e.g., -r 150 = 0.25")
-s papersize
Sets the paper size. Possible values for papersize are a4 (A4), letter or us (US Letter, 8.5"x11"), and legal (US Legal, 8.5"x14").
The default is US Letter.
-t topmargin
Sets the top margin topmargin in units of 1/600 inches (ie -t 150 = 0.25")
-v printertype
Selects the printer model. Possible values of printertype are: 710, 712, 720, 722, 820 and 1000. The default is the HP DeskJet 7X0
Series (710, 712, 720, 722).
-x xoffset
Sets the x-offset xoffset from the left of the page. Units are 1/600 inches
-y yoffset
Sets the y-offset yoffset from the top of the page. Units are 1/600 inches
NOTES
The configuration file is read in first. Command line arguments then modify the resulting definitions.
The -x and -y options accumulate. The -v option resets all definitions back to an inbuilt default for that printer and should be used
before subsequent -b -l -r, -t, -x, and -y arguments.

HISTORY

its successor pnm2ppa will support color printing.
BUGS
This is a stable driver, but does not support color printing.
