- We have printers with versions 47.0, 50.5, 52.3 and probably others,
- andghostscript says it is version 54. I don't believe we have any
- printersbefore version 47.0 and if we do, I don't think we care about
- them. We couldeven cut out the 47.0 printers without a problem (I think
- we only have 3 ofthem).

- No, in fact I would prefer a postscript previewing program that
- usesghostscript even for the current troff setup. This would allow
- drawings andrasters to be seen in the previewed document. I suppose the
- old preview couldbe retained as a speedy ``draft'' previewer as long as
- troff is still used. Ibelieve ATK has all the functionality required to
- implement a ghostscriptpreviewer--we just need someone with the time to
- do it.

- Obviously you've never had your fingers in txttroff.c :-). Not for the
- faintof heart! But I could read this comment another way...are you
- suggesting ATKproduce troff dvi directly? How about TeX dvi? I am not
- sure what the winwould be, other than more printer types would be
- supported. Of courseghostscript can be used to format postscript onto
- other printer types (albeita bit slowly...but on an IBM 6000,
- ghostscript can drive a DeskJet 500 fasterthan many laser printers!).

- TeX and Lout are the only other formatters that come to mind as
- ``free.'' Arethere others? TeX certainly falls in the ``is as
- complicated to build andinstall as groff'' category. Many universities
- already have it installed, soit would potentially be less of a problem
- than groff. Still, TeX is very bigand relatively slow compared to
- ditroff. But in a one-on-one battle withditroff, TeX would certainly
- win as more easy to maintain a ATK->formatterconvertor.

- I assume the datastream would not change at all...even if the document
- isdisplayed in WYSIWYG format. The only additions to the datastream
- would benew functions that cannot be currently implemented (text flows
- formulti-column output, physical page size, etc). I would imagine that
- a WYSIWYGview could be turned off so that the text can fill the window
- as efficientlyas possible as it does today.
-
- I think a class similar to graphic (subclass of graphic) to render
- postscriptwould result in the biggest short term win. Many (most) ATK
- developersignore printing because it is just too damn hard. Either
- you've got to know alot about postscript to draw something, or you have
- to learn lots about troffand its ugly macros. And the fact that these
- insets are wired to eitherpostscript or troff makes it even harder to
- change printing in the future!
-
- In the long run, ATK's printing has got to change. Troff just can't
- handlecomplicated things like references (i.e. see page xxx) and
- indexes. Thecurrent implementation is a great big hack. I would fear
- that TeX wouldsimply change this to a little big hack.
