[cups.general] Getting a Laserjet CR -> CR/LF filter to work.

[marc+cups at milestonerdl.com]

I'm trying to replace LPRng with CUPS on an new install.

LPRng uses the filter ifhp and this filter allows for CR to CR/LF
conversions like unix2dos can do.

The closed source custom application outputs:
1b 28 73 31 36 2e 36 36  68 37 76 30 54 1b 39 1b  |.(s16.66h7v0T.9.|
26 6c 35 63 33 65 31 30  35 46 1b 26 61 31 4c 0a  |&l5c3e105F.&a1L.|
0a 0a 20 20 20 20 20 20  20 20 20 20 20 20 20 20  |..              |
so the normal 'make the text postscript' is not going to work
as the 'raw text' is PCL.

Is there a already written script/program to do this conversion
for insertion into /usr/lib/cups/filter/ ?
