# Printing Dialog

The OpenEV Print Dialog is used to capture the contents of a view for printing, or other purposes.

- Driver: One of:
  1. PostScript: This is the only driver that supports the Paper and Scale controls in order to control placement on a page. The Output Type: Greyscale option should produce Level 1 PostScript that will work on any PostScript print.

  2. TIFF: Produces an RGB or Greyscale TIFF file. The resulting file is not georeferenced.

  3. PNG: Produces an RGB or Greyscale PNG file suitable for web publishing.

  4. Windows Print Driver: Prints via an installed MS Windows print driver. In this case the Print button leads to a dialog for selection of a specific driver, and control of other printer options. The image will always be printed as large as possible given the selection of paper type.

- Device: Select whether the resulting output is spooled directly to the printer or saved to a file. This option is always File for PNG and TIFF, and always Spool To Printer for Windows Print Driver. PostScript may be spooled, or directed to a file.

- File/Command: If the Device is File this is the name of a file to save the print to. If it is Spool to Printer this will be a command to be used to spool to the printer. The PostScript text will be directed to the standard input of the indicated command.

- Output Type: Either Greyscale or Color to control the type of output produced.

- Paper: (PostScript only) Select the paper size. This is used to establish size and positioning of the view.

- Scale: (PostScript only) Modifies the scale at which the print is produced. A value of 0.5 would cause the view to be 50% the normal size, but still centered on the paper.

- Resolution: The resolution at which the current view will be rendered for output. A value of 2.0 would cause the view to be internally rendered at double the resolution of the screen display for output.
