Read_Me file for NEC printers.
------------------------------

The "NEC.P6-Plus" printer definition file is for use with the NEC P6 Plus
and NEC compatible 24 pin printers. Most of the graphics resolutions are 24
pin dumps. The 360 DPI vertical resolution graphics dumps are interlaced and
as such require the support of the FS "3" <n> control sequence to set n/360 
inch line pitch. Note that colour printing should only be selected if you
have installed a colour ribbon in your NEC P6 Plus - the ribbon that comes
with the NEC P6 Plus is black only. ISO Latin 1 text characters are obtained
by using ESC "t" 1 and ESC "6" to select IBM character set 2 instead of
italic characters for the top bit set printer characters. In addition ESC
"R" <n> sequences are used to print some of the characters.

The "NEC.P6-Plus" file will in fact work with many Epson compatible 24 pin
printers, with the exception of the 360 DPI vertical resolution graphics
modes which use the NEC specific command.

Colour printing is only performed for non interlaced graphics printouts ie.
180 by 180 DPI or lower. There are two reasons for this. Firstly, interlaced
colour printing would involve an excessively large number of print head
passes (8 or 16) over the same line on the paper. Also, on the second or
subsequent interlace passes the light ribbon colours (eg. yellow) would be
printing on top of dark colours already on the paper. This causes
contamination of the lighter ribbon colour and seriously reduces usable
ribbon life - unless you are happy with muddy yellows.
