This document describes printing functions within Super ZZ Zero. If you do
not intend to use the printing functions, then you may ignore them. If you
just want to write text to a file for later reference and do not need to
use a printer, then you should use printer type "0".

The first character of config.printer_type must be the printer type major
code which is one of the codes below:

  0 = Plain text
  1 = Epson

After that will be the options specific to the printer type, which are
described in the below sections.


=== Plain text (0) ===

This printer type is used when you do not want to use the control codes of
any specific kind of printer; it can send the text directly.

The following option characters are possible:

  0 = ASCII only (default)
  1 = PC character codes 128-255 but not 0-31
  2 = All PC character codes, except NUL, CR, LF, FF
  C = Send CR only
  F = Send a form feed after printing is completed
  L = Send LF only
  X = Send CRLF (default)


=== Epson (1) ===

This printer type is for many Epson printers as well as other printers
that support the ESC/P command set, including some dot matrix printers
from other manufacturers. Refer to the documentation of your printer to
determine which commands are supported.

@ will automatically initialize the printer settings by the ESC @ command
and other appropriate commands. If you need customized initialization,
you should use config.printer_begin to set up your own initialization,
instead of using this command.

B will ring the bell in the printer at the beginning and end of the print
job (only valid for printers that have an internal bell).

C enables colour printing (only valid for colour printers).

N causes it to not send line feeds (only carriage returns will be sent).

P means the PC character set is fully supported. Only printers with ESC/P 2
are capable of this.


=== PostScript ===

This software does not directly support printing using PostScript. To print
using PostScript, you must install a PostScript program which will emulate
one of the above printer types.

(Emulation files are not currently included with this software, but they
may be added in future, in which case they will be documented here.)


=== Printer-type-independent options ===

The config.printer_option may be set to a list of options that will work in
the same way regardless of the printer type. The default setting depends on
the printer type.

Separate these options by commas. Each one has the format of one letter and
then one or more digits to give a numeric value to that option.

B is the number of blank lines to add before each print, from 0 to 255.

C is 1 to center headings or 0 to not center headings.

L is the number of lines per page; it will automatically send a form feed
after the specified number of lines.

S is the starting line offset. This can be used if config.printer_begin is
used to print a heading. If there is no such heading, this should be zero.

T tells whether or not to print the title: 1 to print, 0 to not print. You
may also specify 2 for wide printing.

W is the maximum number of characters on each line. Longer lines will be
truncated to the specified length. The maximum width is 255 characters.

Z means continuous printing; do not add a form feed after a print job and
do not reinitialize the printer after each print job either (it will only
be initialized once). This also prevents resetting the printer after the
printing is completed. Set to 1 to enable or 0 to disable.
