bool printer_set_option ( resource handle, int option, mixed value)

The function sets the following options for the current connection. `handle` must be a valid handle to a printer. For `option` can be one of the following constants:

- `PRINTER_COPIES`: sets how many copies should be printed, `value` must be an integer.

- `PRINTER_MODE`: specifies the type of data (text, raw or emf), `value` must be a string.

- `PRINTER_ORIENTATION`: specifies the orientation of the paper, `value` can be either PRINTER_ORIENTATION_PORTRAIT or PRINTER_ORIENTATION_LANDSCAPE

- `PRINTER_RESOLUTION_Y`: specifies the y-resolution in DPI, `value` must be an integer.

- `PRINTER_RESOLUTION_X`: specifies the x-resolution in DPI, `value` must be an integer.

- `PRINTER_PAPER_FORMAT`: specifies the a predefined paper format, set `value` to PRINTER_FORMAT_CUSTOM if you want to specify a custom format with PRINTER_PAPER_WIDTH and PRINTER_PAPER_LENGTH. `value` can be one of the following constants.

  - `PRINTER_FORMAT_CUSTOM`: let's you specify a custom paper format.

  - `PRINTER_FORMAT_LETTER`: specifies standard letter format (8 1/2- by 11-inches).

  - `PRINTER_FORMAT_LETTER`: specifies standard legal format (8 1/2- by 14-inches).

  - `PRINTER_FORMAT_A3`: specifies standard A3 format (297- by 420-millimeters).

  - `PRINTER_FORMAT_A4`: specifies standard A4 format (210- by 297-millimeters).

  - `PRINTER_FORMAT_FOLIO`: specifies standard FOLIO format (8 1/2- by 13-inch).

- `PRINTER_PAPER_LENGTH`: if PRINTER_PAPER_FORMAT is set to PRINTER_FORMAT_CUSTOM, PRINTER_PAPER_LENGTH specifies a custom paper length in mm, `value` must be an integer.

- `PRINTER_PAPER_WIDTH`: if PRINTER_PAPER_FORMAT is set to PRINTER_FORMAT_CUSTOM, PRINTER_PAPER_WIDTH specifies a custom paper width in mm, `value` must be an integer.

- `PRINTER_SCALE`: specifies the factor by which the printed output is to be scaled. the page size is scaled from the physical page size by a factor of scale/100. for example if you set the scale to 50, the output would be half of it's original size. `value` must be an integer.

- `PRINTER_BACKGROUND_COLOR`: specifies the background color for the actual device context, `value` must be a string containing the rgb information in hex format i.e. "005533".

- `PRINTER_TEXT_COLOR`: specifies the text color for the actual device context, `value` must be a string containing the rgb information in hex format i.e. "005533".

- `PRINTER_TEXT_ALIGN`: specifies the text alignment for the actual device context, `value` can be combined through OR'ing the following constants:

  - `PRINTER_TA_BASELINE`: text will be aligned at the base line.

  - `PRINTER_TA_BOTTOM`: text will be aligned at the bottom.

  - `PRINTER_TA_TOP`: text will be aligned at the top.

  - `PRINTER_TA_CENTER`: text will be aligned at the center.

  - `PRINTER_TA_LEFT`: text will be aligned at the left.

  - `PRINTER_TA_RIGHT`: text will be aligned at the right.
