- Depending on your applications, you may not even need Freedom of the Press to
- get comparable output. Do you need postscript capability in particular? FotP
- will only be useful for applications that know how to drive postscript
- printers, but not how to produce the same quality on the PLW LS. For example
- Microsoft Word 4.0 doesn't know how to draw high resolution rotated text or
- hairlines on the LS. An application like Canvas 3 is capable of producing
- almost identical output on both printers.
-
- The LS can not do (true) greyscale pictures (and I doubt FotP will help!), I
- don't know whether the NTR does greyscales or not.

- Sorry, but you're wrong, and again the physical evidence proves it! I also
- have a PLW LS, and as long as the application doing the printing knows what to
- do, the output is almost identical to a more expensive postscript printer.
- However the PLW LS is a dumb printer, the program from which you are printing
- has to know how to draw your picture right down to the last ink dot. Many
- programs do not know how to print rotated text for example, so it gets
- bitmapped at low resolution (since they know how to do that for the screen
- image) and it looks awful on the printout! The same program could tell a smart
- postscript printer to print rotated text, and the printer knows how to do a
- beautiful job. The postscript printer also has a number of fonts built in,
- which is how it can print them nicely even though you don't have them on your
- mac. The LS relies on your Mac and application knowing how to draw the font.
-
- For run-of-the-mill text and graphics, the only difference I am aware of
- between the printers is speed, and depending on the printer, perhaps a tiny
- quality difference. For more sophisticated work, I dunno. I bought the LS
- because it was cheaper and I couldn't see any significant advantages to
- postscript, since TrueType supplies the scalable fonts.
