;;
+;; To print only one header at the top of each page,

;; The font family and size of text in the header are determined
;; by the variables `ps-header-font-family', `ps-header-font-size' and

;; for your printer.
;;
;;
+;; Control And 8-bit Characters
+;; ----------------------------
+;;
+;; The variable `ps-print-control-characters' specifies whether you want to see
+;; a printable form for control and 8-bit characters, that is, instead of
+;; sending, for example, a ^D (\004) to printer, it is sent the string "^D".
+;;
+;; Valid values for `ps-print-control-characters' are:
+;;
+;; 8-bit This is the value to use when you want an ascii encoding of
+;; any control or non-ascii character. Control characters are
+;; encoded as "^D", and non-ascii characters have an
+;; octal encoding.
+;;
+;; control-8-bit This is the value to use when you want an ascii encoding of
+;; any control character, whether it is 7 or 8-bit.
+;; European 8-bits accented characters are printed according
+;; the current font.
+;;
+;; control Only ascii control characters have an ascii encoding.
+;; European 8-bits accented characters are printed according
+;; the current font.
+;;
+;; nil No ascii encoding. Any character is printed according the
+;; current font.
+;;
+;; Any other value is treated as nil.
+;;
+;; The default is `control-8-bit'.
+;;
+;; Characters TAB, NEWLINE and FORMFEED are always treated by ps-print engine.
+;;
+;;
;; Line Number
;; -----------
;;
;; The height, in lines, of each rectangle is controlled by
;; the variable `ps-zebra-stripe-height', which is 3 by default.
;; The distance between stripes equals the height of a stripe.
-;;
+;;
;; The variable `ps-zebra-stripes' controls whether to print zebra stripes.
;; Non-nil means yes, nil means no. The default is nil.
;;
;; See also section How Ps-Print Has A Text And/Or Image On Background.
;;
;;
-;; Font managing
+;; Hooks
+;; -----
+;;
+;; Ps-print has the following hook variables:
+;;
+;; `ps-print-hook'
+;; It is evaluated once before any printing process. This is the right
+;; place to initialize ps-print global data.
+;; For an example, see section Adding a New Font Family.
+;;
+;; `ps-print-begin-page-hook'
+;; It is evaluated on each real beginning of page, that is, ps-print
+;; considers each beginning of column as a beginning of page, and a real
+;; beginning of page is when the beginning of column coincides with a
+;; paper change on your printer.
+;;
+;; `ps-print-begin-column-hook'
+;; It is evaluated on each beginning of column, except in the beginning
+;; of column that `ps-print-begin-page-hook' is evaluated.
+;;
+;;
+;; Font Managing
;; -------------
;;
;; Ps-print now knows rather precisely some fonts:
;; in points, for the top line of text in the header.
;;
;;
-;; Adding a new font family
+;; Adding a New Font Family
;; ------------------------
;;
;; To use a new font family, you MUST first teach ps-print
;;
;; - Add these values to the `ps-font-info-database':
;; (setq ps-font-info-database
-;; (append
-;; '((Helvetica ; the family name
-;; "Helvetica" "Helvetica-Bold" "Helvetica-Oblique" "Helvetica-BoldOblique"
-;; 10.0 11.56 2.78 5.09243))
-;; ps-font-info-database))
+;; (append
+;; '((Helvetica ; the family key
+;; (fonts (normal . "Helvetica")
+;; (bold . "Helvetica-Bold")
+;; (italic . "Helvetica-Oblique")
+;; (bold-italic . "Helvetica-BoldOblique"))
+;; (size . 10.0)
+;; (line-height . 11.56)
+;; (space-width . 2.78)
+;; (avg-char-width . 5.09243)))
+;; ps-font-info-database))
;; - Now you can use this font family with any size:
;; (setq ps-font-family 'Helvetica)
;; - if you want to use this family in another emacs session, you must
;; (setq ps-font-info-database (append ...)))
;; if you don't want to load ps-print, you have to copy the whole value:
;; (setq ps-font-info-database '(<your stuff> <the standard stuff>))
-;; or, if you can wait until the `ps-print-hook' is implemented, do:
-;; (add-hook 'ps-print-hook '(setq ps-font-info-database (append ...)))
-;; This does not work yet, since there is no `ps-print-hook' yet.
+;; or, use `ps-print-hook' (see section Hooks):
+;; (add-hook 'ps-print-hook
+;; '(lambda () (setq ps-font-info-database (append ...))))
;;
;; You can create new `mixed' font families like:
-;; (my-mixed-family
-;; "Courier-Bold" "Helvetica"
-;; "Zapf-Chancery-MediumItalic" "NewCenturySchlbk-BoldItalic"
-;; 10.0 10.55 6.0 6.0)
+;; (my-mixed-family
+;; (fonts (normal . "Courier-Bold")
+;; (bold . "Helvetica")
+;; (italic . "Zapf-Chancery-MediumItalic")
+;; (bold-italic . "NewCenturySchlbk-BoldItalic")
+;; (w3-table-hack-x-face . "LineDrawNormal"))
+;; (size . 10.0)
+;; (line-height . 10.55)
+;; (space-width . 6.0)
+;; (avg-char-width . 6.0))
;; Now you can use your new font family with any size:
;; (setq ps-font-family 'my-mixed-family)
;;
+;; Note that on above example the `w3-table-hack-x-face' entry refers to
+;; a face symbol, so when printing this face it'll be used the font
+;; `LineDrawNormal'. If the face `w3-table-hack-x-face' is remapped to
+;; use bold and/or italic attribute, the corresponding entry (bold, italic
+;; or bold-italic) will be used instead of `w3-table-hack-x-face' entry.
+;;
+;; Note also that the font family entry order is irrelevant, so the above
+;; example could also be written:
+;; (my-mixed-family
+;; (size . 10.0)
+;; (fonts (w3-table-hack-x-face . "LineDrawNormal")
+;; (bold . "Helvetica")
+;; (bold-italic . "NewCenturySchlbk-BoldItalic")
+;; (italic . "Zapf-Chancery-MediumItalic")
+;; (normal . "Courier-Bold"))
+;; (avg-char-width . 6.0)
+;; (space-width . 6.0)
+;; (line-height . 10.55))
+;;
+;; Despite the note above, it is recommended that some convention about
+;; entry order be used.
+;;
;; You can get information on all the fonts resident in YOUR printer
;; by uncommenting the line:
;; % 3 cm 20 cm moveto ReportAllFontInfo showpage
;; always right. For example, you might want to map colors into faces
;; so that blue faces print in bold, and red faces in italic.
;;
-;; It is possible to force ps-print to consider specific faces bold or
-;; italic, no matter what font they are displayed in, by setting the
-;; variables `ps-bold-faces' and `ps-italic-faces'. These variables
-;; contain lists of faces that ps-print should consider bold or
-;; italic; to set them, put code like the following into your .emacs
-;; file:
+;; It is possible to force ps-print to consider specific faces bold,
+;; italic or underline, no matter what font they are displayed in, by setting
+;; the variables `ps-bold-faces', `ps-italic-faces' and `ps-underlined-faces'.
+;; These variables contain lists of faces that ps-print should consider bold,
+;; italic or underline; to set them, put code like the following into your
+;; .emacs file:

-;; (setq ps-bold-faces '(my-blue-face))
+;; (setq ps-bold-faces '(my-blue-face))
;; (setq ps-italic-faces '(my-red-face))
+;; (setq ps-underlined-faces '(my-green-face))
;;
;; Faces like bold-italic that are both bold and italic should go in
;; *both* lists.
;; get out of sync, if a face changes, or if new faces are added. To
;; get the lists back in sync, you can set the variable
;; `ps-build-face-reference' to t, and the lists will be rebuilt the
-;; next time ps-print is invoked.
