** ps-print changes

There are some new user variables and subgroups for customizing the
page layout.

*** Horizontal layout (subgroup)

The horizontal layout is determined by the variables `ps-left-margin',
`ps-inter-column', and `ps-right-margin'.  All are measured in points.

*** Vertical layout (subgroup)

The vertical layout is determined by the variables `ps-bottom-margin',
`ps-top-margin', and `ps-header-offset'.  All are measured in points.

*** Headers (subgroup)

If the variable `ps-print-header' is nil, no header is printed.  Then
`ps-header-offset' is not relevant and `ps-top-margin' represents the
margin above the text.

If the variable `ps-print-header-frame' is non-nil, a gaudy framing
box is printed around the header.

The contents of the header are determined by `ps-header-lines',
`ps-show-n-of-n', `ps-left-header' and `ps-right-header'.

The height of the header is determined by `ps-header-line-pad',
`ps-header-font-family', `ps-header-title-font-size' and
`ps-header-font-size'.

To print only one header at the top of each page, set
`ps-print-only-one-header' to t.

The variable `ps-spool-config' specifies who is responsable for
setting duplex and page size switches.

If you have a duplex-capable printer (one that prints both sides of
the paper), set `ps-spool-duplex' to t.

The variable `ps-spool-tumble' specifies how the page images on
opposite sides of a sheet are oriented with respect to each other.

*** Font managing (subgroup)

The variable `ps-font-family' determines which font family is to be
used for ordinary text.  Its value must be a key symbol in the alist
`ps-font-info-database'.  You can add other font families by adding
elements to this alist.

The variable `ps-font-size' determines the size of the font for
ordinary text.  It defaults to 8.5 points.

The variable `ps-multibyte-buffer' specifies the ps-print multi-byte
buffer handling.

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

If variable `ps-auto-font-detect' is non-nil, automatically detect
bold/italic face attributes.  If nil, we rely solely on the lists
`ps-bold-faces', `ps-italic-faces', and `ps-underlined-faces'.

*** Color managing (subgroup)

The default foreground and background colors are defined by the
variables `ps-default-fg' and `ps-default-bg'.  On black-and-white
printers, colors are displayed in grayscale.

To turn off color output, set `ps-print-color-p' to nil.

*** Faces managing (subgroup)

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'.

The variable `ps-build-face-reference' specifies to build the
reference face lists.

The variable `ps-always-build-face-reference' specifies if it always
rebuilds the reference face lists.

*** N-up printing (subgroup)

The variable `ps-n-up-printing' specifies the number of pages per
sheet of paper.  The value specified must be between 1 and 100.  The
default is 1.

The variable `ps-n-up-margin' specifies the margin in points between
the sheet border and the n-up printing.  The default is 1 cm (or
0.3937 inches, or 28.35 points).

If variable `ps-n-up-border-p' is non-nil a border is drawn around
each page.  The default is t.

The variable `ps-n-up-filling' specifies how page matrix is filled on
each sheet of paper.

*** Zebra stripes (subgroup)

The variable `ps-zebra-stripes' controls whether to print zebra
stripes.  Non-nil means yes, nil means no.  The default is nil.

The height, in lines, of each zebra stripe is controlled by the
variable `ps-zebra-stripe-height', which is 3 by default.

The variable `ps-zebra-gray' controls the zebra stripes gray scale.
It should be a float number between 0.0 (black color) and 1.0 (white
color).  The default is 0.95.

*** Background image and/or text (subgroup)

The variable `ps-print-background-image' specifies how to print EPS
PostScript images on background.

The variable `ps-print-background-text' specifies how to print text on
background.

*** Printer managing (subgroup)

The variable `ps-printer-name' determines the name of a local printer
for printing PostScript files.

The variables `ps-lpr-command' and `ps-lpr-switches' determine what
command is used to send the PostScript images to the printer, and what
arguments to give the command.

The variable `ps-print-region-function' specifies a function to print
the region on a PostScript printer.

*** Page settings (subgroup)

The variable `ps-paper-type' determines the size of paper ps-print
formats for; it should contain one of the symbols: `a4' `a3' `letter'
`legal' `letter-small' `tabloid' `ledger' `statement' `executive'
`a4small' `b4' `b5' It defaults to `letter'.  If you need other sizes,
see the variable `ps-page-dimensions-database'.

The variable `ps-landscape-mode' determines the orientation of the
printing on the page.  nil, the default, means "portrait" mode,
non-nil means "landscape" mode.

*** Line number, control characters, columns, PostScript headers

The variable `ps-number-of-columns' must be a positive integer.  It
determines the number of columns both in landscape and portrait mode.
It defaults to 1.

It is possible to add PostScript prologue header comments besides that
ps-print generates by setting the variable `ps-print-prologue-header'.

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".

The variable `ps-line-number' specifies whether to number each line;
non-nil means do so.  The default is nil (don't number each line).

If variable `ps-razzle-dazzle' is non-nil, report progress while
formatting buffer.

The variable `ps-adobe-tag' specifies the header line identifying the
output as PostScript.  By default, `ps-adobe-tag' contains the
standard identifier.

If variable `ps-banner-page-when-duplexing' is non-nil, the very first
page is skipped.  It's like the very first character of buffer (or
region) is ^L (\014).
