Do I presume correctly that those commands work only with Postscript
printers, and whatever file I'm printing needs to be data in a format
recognized by the printer?  In other words, no direct printing of
.html, .doc, .pdf, etc. files without first generating postscript (or
some other printer-native format)?

It would be great if I were wrong, but if I'm right it would hardly be
worth the effort in most cases.  I'd rather shell out some bucks for
TuboPrint if it makes things easy.
