A flow path switching device comprising two flow paths having pressure losses different from each other, and a valve body provided corresponding to one of the two flow paths which has a lower pressure loss, the two flow paths being switched by opening/closing the flow path having the lower pressure
A flow path switching device comprising two flow paths having pressure losses different from each other, and a valve body provided corresponding to one of the two flow paths which has a lower pressure loss, the two flow paths being switched by opening/closing the flow path having the lower pressure loss with the valve body, and a shower unit having the flow path switching device. It is possible to provide a low pressure-loss flow path switching device for which it is not necessary to open/close the two flow paths at the same time and which is simple in construction and can save space. Further, if this flow path switching device is used in a purified water shower unit having a raw water flow path and a purified water flow path, then it is possible to provide a purified water shower unit which ensures that switching operation can be performed easily by one hand, that a filter material can sufficiently maintain its shape even when water pressure is applied to the filter material, that the filter material is worn off efficiently over the whole, and that space in the unit is efficiently used.

The method of claim 1, wherein the step of providing predetermined, numeric media identifiers within document presentation architecture in said data processing system, further comprises: establishing an identifier registry in said presentation architecture; installing a unique, numeric identifier for each commonly available media type; reserving unused numeric identifiers for user defined media types; and adding said user defined media types to said registry. 5. The method of claim 1, wherein the step of determining whether a form definition associated with said print request specifies a numeric identifier, a descriptive name, a printer bin number or no identifier, further comprises: querying said print request for media requirement; searching first for said numeric identifier; if no said numeric identifier, searching for said descriptive name; if no said descriptive name, searching for said printer bin number; and if no said printer bin number, sending said print request to printer default bin. 6. The method of claim 1, wherein the step of supplying said print server with information from said printer regarding a media source with associated bin information including bin number, media name and numeric media identifier, further comprises: receiving a signal from said printer containing said numeric identifier for said media source wherein said signal includes bin information for said media; and sending said print request to said printer. 7. In a network, a data processing system comprising: at least one printer system connected to said data processing system through said network; a printer server connected to said network; numeric media identifiers stored within document presentation architecture in said data processing system; program logic associated with said printer server for determining whether a form definition associated with a print request specifies a numeric identifier, a descriptive name, a printer bin number or no identifier; and logic associated with said printer for supplying said print server with information from said printer regarding a media source with associated bin information including bin number, media name and numeric media identifier. 8. The data processing system of claim 7, further comprising: logic for sending a notification to requester of said print job, in response to a signal from said printer that said requested media is unavailable, whether to query alternate printers on said network if requested media is unavailable from said printer. 9. The data processing system of claim 8, further comprising: program logic for sending said print job to a second printer on said network as defined by said requester of said print job. 10. The data processing system of claim 7, wherein numeric media identifiers stored within document presentation architecture in said data processing system, further comprises: a registry in said presentation architecture for media types; a unique, numeric identifier associated with each commonly available media type; and reserved numeric identifiers for addition of new, non-registered media types. 11. The data processing system of claim 7, wherein program logic for determining whether a form definition associated with said print request specifies a numeric identifier, a descriptive name, a printer bin number or no identifier, further comprises: means for querying said print request for media requirement; logic means for searching fist for said numeric identifier, then searching for said descriptive name if no said identifier, then searching for said printer bin number if no said descriptive name; and logic means for sending said print request to printer default bin if no said printer bin number. 12. The data processing system of claim 7, wherein program logic for supplying said print server with information from said printer regarding a media source with associated bin information inc
