dvips(k) state and maintainer

Who is the one who currently maintains dvips? I have some trouble with 
partially encoded fonts with non-standard encoding and late postscript 
interpreters in recent hp printers.

unfortunately, I have no idea who is the current maintainer. ctan has 
dvips versions up to 5.67, dvipsk to 5.78a, and 
http://www.radicaleye.com/dvipsalpha.html talks of 5.83 as being 
current. However, tetex 1.0.6 comes with 5.86.

Below the description of the problem:
I have written a short test text which uses a few characters of an 
expert font. When running dvips on the resulting dvi file with partial 
font encoding on, it shortens the definition of the Encoding vector to

/Encoding 256 array
dup 58 /ff put
dup 63 /ffi put
dup 64 /ffl put
readonly def

. Our postscript printers hp 2000n and clj 4050 complain and do not 
print: "Error: typecheck; OffendingCommand: definefont". They are 
right, since the postscript specs say "All unused posistions must
be filled with the name .notdef"

When inserting the following line after "... array", the error vanishs:
	0 1 255 {1 index exch /.notdef put} for

Ideas or references? Thank you, greetings,
