Why do you need this script?
I think it's a bit fragile because it only looks for the string  
"showpage" without context.
It could catch the word "showpage where it is not a PostScript operator  
or it could delete the operator "showpage" in a procedure definition  
leaving a broken procedure.
In PostScript you can define a procedure like this
/SP { showpage } def
and use the procedure name (SP) instead of showpage.

I don't understand this command.
pdf2fax should create a fax image document while the filter script  
seems to process PostScript code.

I think the empty line followed by the word "showpage" makes Hylafax  
think it's a text file (and not PostScript) but this is followed by  
binary Tiff image data. This is converted to PostScript and probably is  
bad postScript code because the text to PostScript converter does not  
handle binary data.
