I think I used the term winprinter a little bit too generically.

Most inkjets have no brains in them.  They are pretty much like the
dot-matrix printers of yore.  The page is assembled graphically in your
computer and fed to them one in bitmap form, one row/swipe at a time. 
These printers aren't actually winprinters though.  Technically
winprinters are printers that essentially take data in the form of raw
Windows GDI (graphic device interface) data streams.  The problem here
is that they work the same way as the printers I just mentioned--they
get fed a data stream and print one swipe at a time--but to print to
them you have to have some kind of GDI implementation/emulation.  The
problem is equivalent to reverse-engineering MS Office file formats. 
This is probably a gross over-simplification of the issues, but that's
the general idea.  

I'm pretty sure that most of HP's printers aren't GDI printers, even the
simple inkjets, which makes Linux support easier.

I'm extremely grateful that HP has good linux supporters inside that
develop drivers and other forms of support.  Linux end-users represent
such a small market (maybe half of the macintosh market) that most
companies don't even find it worth their while.  

For some reason many of the companies that have no linux support also
refuse to release any specifications either, trying to protect some
small advantage they have.  Then in the end, those that really want it
reverse-engineer it anyway.  HP as always been pretty good with their
hardware as far as this type of thing goes.
