void setSetting(String settingId,
              String value)
                throws SettingsException

Sets the setting to the given value.

Parameters:

getSettingRange

String getSettingRange(String settingId)
                       throws SettingsException

Retrieves the allowable range for a setting.

Parameters:

settingId - setting id.

Returns:

the setting's range as a string

Throws:

SettingsException - if the setting does not exist

isSettingValid

boolean isSettingValid(String settingId,
                     String value)
                       throws SettingsException

Returns true if value is valid for the given setting.

Parameters:

settingId - setting id.

value - the setting's value

Returns:

true if value is valid for the given setting.

Throws:

SettingsException - if the setting does not exist

isSettingReadOnly

boolean isSettingReadOnly(String settingId)
                          throws SettingsException

Returns true if the setting is read only.

Parameters:

settingId - the setting id

Returns:

true if the setting is read only

Throws:

SettingsException - if the setting does not exist

isSettingWriteOnly

boolean isSettingWriteOnly(String settingId)
                           throws SettingsException

Returns true if the setting is write only.

Parameters:

settingId - the setting id

Returns:

true if the setting is write only

Throws:

SettingsException - if the setting does not exist

getSettingType

String getSettingType(String settingId)
                      throws SettingsException

Returns the data type of the setting.

Parameters:

settingId - the setting id

Returns:

the data type of the setting (e.g. string, bool, enum, etc.)

Throws:

SettingsException - if the setting does not exist

processSettingsViaMap

Map<String,String> processSettingsViaMap(Map<String,String> settingValuePairs)
                                         throws SettingsException,
                                                ConnectionException

Change or retrieve printer settings.

Note: Due to the setting verification and validation, additional time and data traffic will be needed for each processSettingsViaMap method call. It is recommended to bundle all settings into one map and one method call to reduce this overhead.

Parameters:

settingValuePairs - The settings to change or retrieve

Returns:

Map results of the setting commands

Throws:

SettingsException - If a setting is malformed, or one or more settings could not be set.

ConnectionException - If there is an error communicating with the printer.
