## Detailed Description

The printer type represents a printer model.

A particular printer model must selected in order to be able to print. Each printer model provides default print options through a default vars object.

## Typedef Documentation

typedef struct stp_family stp_family_t

typedef struct stp_printer stp_printer_t

The printer opaque data type (representation of printer model).

## Function Documentation

Parameters

  v | the vars to use.

Returns
  list of options in a string list ('name' is the name of the option; 'text' is the value it takes on). NULL return means no external options are required. User must stp_string_list_destroy the list after use.

const stp_printer_t* stp_get_printer_by_device_id | ( | const char * | device_id | ) |

Get a printer model by its IEEE 1284 device ID.

Parameters

  device_id | the printer model's device ID.

Returns

Get a printer model by its foomatic ID.

Parameters

  foomatic_id | the printer model's foomatic ID

Returns
  a pointer to the printer model, or NULL on failure. The pointer should not be freed.

const stp_printer_t* stp_get_printer_by_index | ( | int | idx | ) |

Get a printer model by its index number.

Parameters

  idx | the index number. This must not be greater than (total number of printers - 1).

  a pointer to the printer model, or NULL on failure. The pointer should not be freed.

const stp_printer_t* stp_get_printer_by_long_name | ( | const char * | long_name | ) |

Get a printer model by its long (translated) name.

Parameters

  long_name | the printer model's long (translated) name.

Returns
  a pointer to the printer model, or NULL on failure. The pointer should not be freed.

int stp_get_printer_index_by_driver | ( | const char * | driver | ) |

Get the printer index number from the printer model short (driver) name.

Deprecated:
  There should never be any need to use this function.
  Parameters

    driver | the printer model's short (driver) name.

  Returns
    the index number, or -1 on failure.

void stp_initialize_printer_defaults | ( | void |  | ) |

| ) |  |

const stp_vars_t* stp_printer_get_defaults | ( | const stp_printer_t * | p | ) |
