Windows Printer
.PP
.B pdftocairo
reads the PDF file,
.IR PDF-file ,
and writes to
.IR output-file .
The image formats (PNG, JPEG, and TIFF) generate one file per page with the page number and file type appended to
.IR output-file
(except when \-singlefile is used).
When the output format is a vector format (PDF, PS, EPS, and SVG) or when \-singlefile is used,
.IR output-file
is the full filename.

If the
.IR PDF-file
is \*(lq\-\*(rq , the PDF is read from stdin.
If the
.IR output-file
is \*(lq\-\*(rq , the output file will be written to stdout. Using stdout is not valid with image formats unless \-singlefile is used.
If
.IR output-file
is not used, the output filename will be derived from the
.IR PDF-file
filename.
.PP
Not all options are valid with all output formats. One (and only one) of the output format options (\-png, \-jpeg, \-tiff, \-pdf, \-print, \-ps, \-eps, or \-svg) must be used.
.PP
The resolution options (\-r, \-rx, \-ry) set the resolution of the
image output formats. The image dimensions will depend on the PDF page
size and the resolution. For the vector outputs, regions of the page
that can not be represented natively in the output format (eg
translucency in PS) will be rasterized at the resolution specified by
the resolution options.
.PP
The \-scale-to options may be used to set a fixed image size. The
image resolution will vary with the page size.
.PP
The cropping options (\-x, \-y, \-W, and \-H) use units of pixels with
the image formats and PostScript points (1/72 inch) with the vector
formats. When cropping is used with vector output the cropped region is
centered unless \-nocenter is used in which case the cropped region is
at the top left (SVG) or bottom left (PDF, PS, EPS).

 If an output file is not specified, the output will be sent to the printer.
 The output file '-' can not be used with this option.

is set to -1, the horizontal size will determined by the aspect ratio
of the page (PNG/JPEG/TIFF only).

.TP
.BI \-paper " size"
Set the paper size to one of "letter", "legal", "A4", or "A3"
(PS,PDF,SVG only).  This can also be set to "match", which will set

By default, printing output is cropped to the CropBox specified in the PDF
file.  This option disables cropping (PS,PDF,SVG only).
.TP
.B \-expand
Expand PDF pages smaller than the paper to fill the paper (PS,PDF,SVG only).  By
default, these pages are not scaled.
.TP
.B \-noshrink
Don't scale PDF pages which are larger than the paper (PS,PDF,SVG only).  By default,
pages larger than the paper are shrunk to fit.
.TP
.B \-nocenter
By default, PDF pages smaller than the paper (after any scaling) are
centered on the paper.  This option causes them to be aligned to the
lower-left corner of the paper instead (PS,PDF,SVG only).
.TP
.B \-duplex
Adds the %%IncludeFeature: *Duplex DuplexNoTumble DSC comment to the
PostScript file (PS only).  This tells the print manager to enable duplexing.
.TP
.BI \-printer " printer-name"

.B WINDOWS PRINTER OPTIONS
for the available options.
.TP
.BI \-setupdlg
(Windows only). When used with \-print, the printer properties dialog is displayed
allowing the print settings to be modified before printing. The paper size selected
in the print properties dialog will be used except when -origpagesizes is specified.
.TP
.BI \-opw " password"
Specify the owner password for the PDF file.  Providing this will
bypass all security restrictions.

.SH WINDOWS PRINTER OPTIONS
In Windows, you can use the \-print option to print directly to a system printer. Additionally, you can use the \-printopt 
option to configure the printer. It takes a string of the form "<opt>=<val>[,<opt>=<val>]". Currently the available options are:
.TP
.BI source
Selects the source paper tray to be used (bin). The possible values are "upper", "onlyone", "lower", "middle", "manual", "envelope",
"envmanual", "auto", "tractor", "smallfmt", "largefmt", "largecapacity", "formsource", or a numeric value to choose a driver specific source.
.TP
.BI duplex
Sets the duplex mode of the printer. The possible values are "off", "short" or "long",
indicating no duplexing, short-edge binding, or long-edge binding, respectively.
General option \-duplex is a synonym of "duplex=long". If both options are specified,
\-printopt has priority.
