[comp.sys.next] Alternate printers

rbp@investor.pgh.pa.us (Bob Peirce #305) (02/14/91)

Yesterday I followed up to an article on alternate printers for the NeXT
discussing my experience to date with an Epson LQ-510.  I have a bit more
experience to report.

First, the best results for non-emphasized type seem to come from using
WriteNow and selecting the proper margins and point size and saving as
ascii with inserted line feeds.  I ended up using 14 pt.  with a line of
6.5" and sending output to the printer set up for Times Roman
Proportional with a 10 character indent.  What I got was exactly what
I saw, except as noted below.  Now, what the heck's a point? 

It would be nice if I could estimate the required point size based on
knowledge of the printer and the size of the type.  Believe it or not,
Digital Webster has no comment and searching the manuals for point
produced too many possibilities to read!  So, what's the point?

Second, indents not produced by spacing are lost when you save the file
as ascii.  Therefore, you have to use spacing to center text and for
other indents, but centering doesn't translate to the printer properly. 
I think it has something to do with different ideas of the meaning of a
space between WriteNow and the Epson.  I would like to know what that
difference is.  It probably has something to do with points again. 

Emphasis also is lost when you store the file as ascii.  I don't know if
it is possible to insert escape sequences in WriteNow text, and I have to
test whether sequences inserted with vi are preserved when the file is
loaded back in to WriteNow.  At any rate, escape sequences can be
inserted into the finished document by using vi, but this should
probably be the last thing before printing.

1 point = 1/72 inch.  (ie, 72 point type is 1 inch tall)

In office supply stores, by the way, you should be able to buy an
eye-piece that allows you to accurately measure point size.

Actually, a point is 1/72.27 inches according to the pros.  Only PostScript
insists on thinking that a point is 1/72 inches.  I've wondered if a TeX
ruler that is made by dvips ends up wrong because of this?  (TeX uses the
correct value.)  I've never tested it.
