具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实例用于说明本发明，但不用来限制本发明的范围。
图1为本发明一实施例提供的一种打印设备的选择方法的流程示意图；参考附图1可知，本实施例提供了一种打印设备的选择方法，该方法的执行主体可以为服务器，该服务器与多个打印设备通信连接，并可以接收到用户端所发送的数据信息； 具体的，该方法包括：
S101：接收用户端发送的打印作业以及与打印作业相对应的打印作业参数。
其中，打印作业参数可以包括以下至少之一：色彩、每英寸点数dpi、纸张类型、纸张大小、自动双面等等，可以理解的是，打印作业参数并不限于上述具体的类型参数，还可以包括其他类型参数；另外，在用户需要进行打印操作时，可以通过用户端向服务器发送打印作业以及相对应的打印作业参数；此时，服务器可以直接接收并识别出打印作业和相应的打印作业参数。当然的，本领域技术人员还可以采用其他的方式来接收打印作业和打印作业参数，只要能够保证打印作业和打印作业参数接收的准确可靠性即可。
S102：将本地存储的多个打印设备的打印能力参数与打印作业参数进行分析对比。
其中，在接收到打印作业和打印作业参数之后，服务器可以对打印作业参数进行分析处理，具体的，在服务器本地存储有多个打印设备的打印能力参数，该打印能力参数可以包括以下至少之一：色彩、每英寸点数dpi、纸张类型、纸张大小、自动双面等等；可以理解的是，打印能力参数并不限于上述具体的类型参数，还可以包括其他类型参数；在对打印作业参数进行分析处理时，可以将本地存储的打印能力参数与打印作业参数进行分析对比，需要说明的是，由于打印能力参数和打印作业参数均可以包括多个类型参数，因此，在进行分析对比时，需要将所有的类型参数进行一一对比，以保证分析对比的精确可靠性；例如：若打印能力参数包括：色彩、每英寸点数dpi、纸张类型、纸张大小、自动双面，打印作业参数包括：色彩、纸张大小、自动双面，那么，在对打印作业参数进行分析处理时，需要将打印作业参数中的色彩参数与打印能力参数中的色彩参数进行分析对比，将打印作业参数中的纸张大小参数与打印能力参数中的纸张大小参数进行分析对比，将打印作业参数中的自动双面参数与打印能力参数中的自动双面进行分析对比，从而实现了对打印作业参数进行较为精确的分析处理过程。
S103：若存在与所述打印作业参数完全匹配的打印能力参数，则将与所述打印作业参数完全匹配的打印能力参数所对应的打印设备确定为目标打印设备，其中，所述目标打印设备用于根据所述打印作业进行打印操作。
当对打印作业参数进行分析处理完毕后，可以获取到分析处理结果，该分析处理结果可以为每个打印设备的打印能力参数与打印作业参数的匹配程度，该匹配程度可以包括两种情况：完全匹配和不完全匹配；当存在与所述打印作业参数完全匹配的打印能力参数时，此时，为了尽可能满足用户的打印作业，可以将与打印作业参数完全匹配的打印能力参数所对应的打印设备确定为目标打印设备；例如：存在打印设备A、打印设备B和打印设备C，上述三个打印设备所对应打印能力参数与打印作业参数的匹配度分别为：80％、100％和70％，那么，则可以将完全匹配的打印设备B确定为目标打印设备。
另外，当存在多个打印设备的能力信息均满足用户的打印任务需求时，也即，存在多个与打印作业参数完全匹配的打印能力参数，此时，则可以在上述多个打印能力参数所对应的打印设备中选择任意一个确定为目标打印设备，或者，也可以在 上述的多个打印设备中，将处于非打印状态、且硒鼓粉量最高的打印设备优先确定为目标打印设备，并可以利用该打印设备直接进行打印操作。
S104：若不存在与所述打印作业参数完全匹配的打印能力参数，则按照预设的选取策略选取多个打印设备，并根据用户选择在多个打印设备确定一目标打印设备，其中，所述目标打印设备用于根据所述打印作业进行打印操作。
其中，按照预设的选取策略选取多个打印设备的实现方式可以包括：获取与打印作业参数匹配度较高的打印能力参数所对应的多个打印设备，具体的，在多个打印设备的打印能力参数与打印作业参数进行分析对比的结果为：不存在与打印作业参数完全匹配的打印能力参数时，云服务器可以获取匹配度较高的多个打印设备的打印能力参数列表信息，并发送给用户端，基于用户的选择，确定目标打印机。
需要注意的是，上述的匹配度较高可以包括以下几种情况：第一种情况：预先设置有匹配度阈值，该匹配度阈值的具体数值可以预先设置，例如，可以为60％、70％或者80％等等；当打印能力参数与打印作业参数的匹配度大于或等于上述匹配度阈值时，则可以确定该打印能力参数所对应的打印设备即为所要选取的匹配度较高的打印设备。第二种情况：预先设置有匹配度排名阈值，该匹配度排名阈值的具体数值可以预先设置，例如，可以为4、5或者6等等；此时，获取打印能力参数与打印作业参数的匹配度，并按照匹配度的大小进行排名，根据匹配度排名阈值确定所要选取的匹配度较高的打印设备，例如，将匹配度排名前5名的打印能力参数所对应的打印设备确定为所要选取的匹配度较高的打印设备。第三种情况：预先设置有数量阈值，该数量阈值的具体数值可以预先设置，例如，可以为4、5或者6等等；当与打印作业参数不完全匹配的打印能力参数的数量小于上述的数量阈值(例如：4个)，则可以不进行任何筛选，直接将上述所有不完全匹配的打印能力参数所对应的打印设备确定为所要选取的匹配度较高的打印设备，即直接获取全部不完全匹配的打印设备的列表信息。当然的，本领域技术人员还可以将匹配度较高的情况设置为其他具体情况，只要能够满足所选取的目标打印设备可以尽量满足用户打印需求的效果即可，在此不再赘述。
具体应用时，当对打印作业参数进行分析处理完毕后，获取的分析处理结果为每个打印设备的打印能力参数与打印作业参数的不完全匹配程度，此时，可以获取与打印作业参数匹配度较高的打印能力参数所对应的多个打印设备；当获取到匹配程度较高多个打印设备之后，可以在多个打印设备中，根据用户的选择确定一目标打印设备，此时，目标打印设备可以为匹配程度最高的打印设备或者匹配程度其次高的打印设备，该目标打印设备可以用来根据打印作业进行打印操作，以满足用户的打印作业。例如：存在打印设备A、打印设备B和打印设备C，上述三个打印设备所对应的打印能力参数与打印作业参数的匹配度分别为：70％、60％和90％，那么，则根据用户的实际需要，综合考虑，用户可以选择匹配程度为70％的打印设备B为目标打印设备；此时，打印设备B是最切合用户需求的打印设备，可以尽量满足用户的打印作业需求。
本实施例提供的打印设备的选择方法，在接收到打印作业和打印作业参数之后，可以对打印作业参数进行分析处理，具体的，将本地存储的多个打印设备的打 印能力参数与打印作业参数进行分析对比，并将与打印作业参数完全匹配的打印能力参数所对应的打印设备确定为目标打印设备，或者，根据用户选择在所选取的多个打印设备中确定一目标打印设备，可以准确、快速地确定目标打印设备，免去了服务器接收打印作业后，服务器分别向与之相互连接的多个打印设备发送打印能力参数请求，并等待打印设备反馈打印能力参数请求的通信交互过程，节省了时间，并且在确定目标打印设备时，当与服务器相互连接的打印设备较多时，用户无需查看每个打印设备的能力信息，减少了用户的工作量，可以最大程度地满足用户的打印需求，克服了现有技术中给用户带来不便的缺陷，提高了该选择方法的实用性，有利于市场的推广与应用。
图2为本发明另一实施例提供的一种打印设备的选择方法的流程示意图；图3为本发明实施例提供的获取与服务器相连接的多个打印设备的身份标识，并获取每个打印设备的打印能力参数的流程示意图一；图4为本发明实施例提供的获取与服务器相连接的多个打印设备的身份标识，并获取每个打印设备的打印能力参数的流程示意图二；在上述实施例的基础上，继续参考附图2-4可知，在接收用户端所发送的打印作业以及与打印作业相对应的打印作业参数之前，需要获取并存储多个打印设备的打印能力参数，具体的，该方法还可以包括：
S201：获取与服务器相连接的多个打印设备的身份标识，并获取每个打印设备的打印能力参数。
其中，打印设备的身份标识可以包括：打印设备的名称、序列号、用户身份标识UID、厂家身份标识PID、MAC地址等等；本实施例对于获取身份标识和打印能力参数的具体实现过程不做限定，本领域技术人员可以根据具体的设计需求进行设置，较为优选的，参考附图3所示，获取与服务器相连接的多个打印设备的身份标识，并获取每个打印设备的打印能力参数可以包括：
S2011：接收打印设备发送的注册请求。
当服务器连接有多个打印设备时，在每个打印设备与服务器进行初次连接时，需要在服务器上对打印设备进行注册，此时，打印设备会向服务器发送注册请求，服务器可以接收到该注册请求，并可以根据该注册请求来判断该打印设备是否已经注册，以实现服务器与打印设备之间的初次连接或者在服务器上注册打印设备。
S2012：根据注册请求在服务器上注册打印设备。
在服务器接收到注册请求之后，可以对该注册请求进行分析处理，以判断该打印设备是否在服务器上进行注册操作；当打印设备在服务器上未进行注册操作时，则可以根据注册请求在服务器上对该打印设备进行注册操作；若打印设备已进行注册操作，则直接执行步骤S2013。
S2013：接收打印设备主动发送的身份标识和打印能力参数。
打印设备可以主动向服务器发送身份标识和打印能力参数，此时，服务器可以接收到打印设备发送的身份标识和打印能力参数，从而保证了打印能力参数和身份标识获取的准确可靠性。
需要注意的是，在执行步骤S2013之前，该选择方法还可以包括：
S20130：向已注册的打印设备发送标识获取请求和能力获取请求，以使得打印 设备根据标识获取请求和能力获取请求反馈打印设备的身份标识和打印能力参数。
在打印设备注册完毕后，如果打印设备不会主动向服务器发送身份标识和打印能力参数，此时，服务器可以通过各种方式尽可能的获取打印设备的所有能力并进行记载保存，具体的，服务器可以向打印设备发送标识获取请求和能力获取请求，打印设备可以接收到标识获取请求和能力获取请求，并可以根据标识获取请求和能力获取请求向服务器发送身份标识和打印能力参数，以使得服务器可以接收并存储打印设备的打印能力参数。
S202：将打印设备的身份标识与打印设备的打印能力参数进行绑定存储。
在获取到打印设备的身份标识和打印能力参数之后，可以将打印设备的身份标识与打印能力参数进行绑定存储，具体的，在身份标识与打印能力参数之间建立映射关系，即若获取到身份标识之后，则可以通过身份标识、并利用上述所建立的映射关系即可确认该打印设备以及所对应的打印能力参数，这样有利于提高多个打印设备的打印能力参数与打印作业参数进行分析对比的精确可靠性。
通过打印设备与服务器之间通信交互，可以使得服务器可以准确地获取到打印设备的身份标识和打印能力参数，并可以将打印设备的身份标识和打印能力参数绑定存储在本地服务器，以便于下次对打印能力参数的调用，这样可以避免每次打印作业时都向打印设备进行打印能力参数的查询，减少了通信交互过程，节省了时间，提高了检索和查询效率，进而能够快速地选择出最优打印设备进行打印操作。
图5为本发明又一实施例提供的一种打印设备的选择方法的流程示意图；在上述实施例的基础上，继续参考附图5可知，在具体应用时，打印设备的打印能力参数可能会存在更新操作，此时，为了保证服务器中所存储的打印设备的打印能力参数与实际工作中的打印设备的打印能力参数相一致，在将打印设备的身份标识与打印设备的打印能力参数进行绑定存储之后，该方法还可以包括：
S301：接收打印设备发送的更新请求，更新请求中包括打印设备的身份标识和打印能力更新数据。
其中，打印设备可以具有更新自检测能力，具体的，可以参考附图8-9所示，打印设备中可以设置有能力更新模块，当用户或管理员通过人机交互界面UI界面或者打印机的webpage界面等方式修改了打印能力配置参数之后，打印设备中的能力更新模块会检测到打印设备的打印能力参数发生了更新，此时，打印设备需要判断服务器是否与打印设备进行连接，若打印设备没有与服务器连接，则打印设备可以继续进行定期循环检测；若打印设备与服务器连接，则可以向服务器发送请求打印能力更新操作，具体的，打印设备会向服务器发送更新请求，更新请求中包括身份标识和打印能力更新数据，以使得服务器接收到更新请求之后可以查找到相应的更新打印设备，并进行相应的更新操作。
需要注意的是，对于接收打印设备发送的更新请求而言，还存在另一种可实现的方式，具体为：在服务器与打印设备通信连接之后，服务器也可以按照预设的检测周期(1天、2天或者5天等等)向打印设备发送检测请求，以检测打印设备的打印能力参数是否发生了更新操作，若打印设备发生了更新操作，打印设备则可以根据检测请求返回更新请求；若打印设备未发生更新操作，打印设备则可以不执行任 何操作，以减少信令的交互过程。
S302：根据身份标识和打印能力更新数据对打印设备的打印能力参数进行更新，并向打印设备反馈更新结果。
在服务器接收到身份标识之后，在存储的多个打印设备中，可以通过身份标识查找到相对应的打印设备，该打印设备具有更新操作，在查找到打印设备之后，可以根据打印能力更新数据对预先存储的打印设备的打印能力参数进行更新，从而使得服务器中存储的打印设备的打印能力参数与实际应用中的打印设备的打印能力参数相一致；在服务器进行更新操作完毕后，可以向打印设备发送更新结果；该更新结果可以包括：更新操作成功和更新操作失败的结果；若打印设备接收到更新操作成功，则继续进行定期循环检测操作；若打印设备接收到更新操作失败，则可以重新向服务器发送更新请求，以使得服务器可以根据该更新请求重新进行更新操作。
在打印设备的打印能力参数存在更新时，通过服务器接收更新请求，其中，更新请求中包括打印设备的身份标识和打印能力更新数据，进而服务器可以根据身份标识和打印能力更新数据对打印设备的打印能力参数进行更新，有效地保证了服务器中所存储的配置数据与实际应用中打印设备的配置数据相一致，保证了打印设备选择的精确可靠性，进而提高了该选择方法使用的稳定可靠性，
图6为本发明再一实施例提供的一种打印设备的选择方法的流程示意图；图7为本发明实施例提供的根据离线原因判断目标打印设备是否可以进行打印操作的流程示意图；在上述实施例的基础上，继续参考附图6-7所示，在进行目标打印设备的选择过程中，与服务器相连接的多个打印设备的状态可以处于在线状态和离线状态，其中，在线状态可以是指打印设备可以随时接收服务器所发送的指令，并可以根据用户发送的打印作业进行打印操作；离线状态可以是指打印设备处于关闭状态或者网络不通，此时，打印设备无法立刻执行相应的打印操作；为了保证目标打印设备可以稳定地满足用户的打印作业，在确定目标打印设备之后，该选择方法还可以包括：
S401：判断目标打印设备是否处于在线状态。
具体判断目标打印设备是否处于在线状态的实现方式可以为：服务器向打印设备发送消息或者状态查询请求，如果打印设备在指定的时间(例如：5s、10s或者15s等等)内能够及时接收到打印设备所发送的反馈信息，说明打印设备处于可打印状态，则可以确定打印设备处于在线状态，否则，打印设备处于不可打印状态，此时打印设备处于离线状态。
S402：若目标打印设备处于在线状态，则控制目标打印设备根据打印作业进行打印操作。或者，
当判断结果为目标打印设备处于在线状态时，则说明该目标打印设备可以立刻接收到服务器的相关指令，进而可以控制目标打印设备根据用户发送的打印作业进行打印操作，从而满足了用户的打印作业。
S403：若目标打印设备处于离线状态，则根据用户的检验结果获取目标打印设备的离线原因。
当判断结果为目标打印设备处于离线状态时，则说明该目标打印设备无法接收 到服务器的相关指令，由于该目标打印设备可以满足用户的打印作业，进而可以根据用户的检验结果获取目标打印设备的离线原因，也即，用户来确定目标打印设备的离线原因，其中，离线原因可以包括：打印设备断电、打印设备与服务器之间断网或者打印设备处于维护状态中等等，在获取到离线原因之后，可以根据用户的检验结果所获取的离线原因进一步判断该目标打印设备能够进行打印操作。例如：当离线原因为打印设备与服务器之间断网，此时，服务器可以重新建立与该打印设备之间的连接，进而可以确定该打印设备可以进行打印操作；当离线原因为打印设备处于维护状态中时，则可以确定该打印设备无法进行打印操作。
S404：根据离线原因判断目标打印设备能否进行打印操作。
在获取到离线原因之后，可以进一步对离线原因进行分析处理，以判断目标打印设备能否进行打印操作，具体的，根据离线原因判断目标打印设备是否可以进行打印操作可以包括：
S4041：若目标打印设备可以进行打印操作，则控制目标打印设备处于在线状态，并根据打印作业进行打印操作。或者，
当对离线原因进行分析判断后，确定目标打印设备可以进行打印操作，则可以先将目标打印设备的工作状态由离线状态变更为在线状态，而后可以控制该目标打印设备根据打印作业执行打印操作。
S4042：若目标打印设备无法进行打印操作，则在其他打印设备中重新确定新的目标打印设备。
当对离线原因进行分析判断后，确定目标打印设备无法进行打印操作，此时，为了满足用户的打印作业，可以在其他打印设备中重新确定新的目标打印设备，具体确定新的目标打印设备的过程与上述过程相同，在此不再赘述。
在进行目标打印设备的选择过程中，与服务器相连接的多个打印设备的状态可以处于在线状态和离线状态，进而，在确定目标打印设备时，通过判断目标打印设备是否处于在线状态，若处于在线状态，则可以直接执行打印操作；若处于离线状态，则根据用户的检验结果获取离线原因，进一步判断该目标打印设备是否能够执行打印操作，这样有效地实现了在保证目标打印设备可以满足用户的打印作业时，该目标打印设备可以执行打印操作的稳定可靠性，进一步提高了该选择方法的实用性。
图10为本发明实施例提供的一种服务器的结构示意图，参考附图10所示，本实施例提供了一种服务器，该服务器可以与多个打印设备通信连接，并且可以在多个打印设备中选择出最合适的打印设备作为目标打印设备，以满足用户的打印作业，具体的，该服务器包括：

其中，在获取模块4获取与服务器相连接的多个打印设备的身份标识，并获取每个打印设备的打印能力参数时，该获取模块4可以用于：接收打印设备发送的注册请求；根据注册请求在服务器上注册打印设备；接收打印设备主动发送的身份标识和打印能力参数。
进一步的，获取模块4还可以用于：在接收所述打印设备主动发送的身份标识和打印能力参数之前，向已注册的打印设备发送标识获取请求和能力获取请求，以使得打印设备根据标识获取请求和能力获取请求反馈打印设备的身份标识和打印能力参数。
存储模块5，用于将打印设备的身份标识与打印设备的打印能力参数进行绑定存储。
本实施例对于获取模块4以及存储模块5的具体形状结构不做限定，本领域技术人员可以根据其实现的功能作用对其进行任意设置，在此不再赘述；另外，该获取模块4以及存储模块5所实现方法步骤的具体实现过程以及实现效果与上述实施例中的步骤S201-S202、S2011-S2013、S20130的具体实现过程以及实现效果相同，具体可参考上述陈述内容，在此不再赘述。
通过打印设备与服务器之间通信交互，可以使得获取模块4可以准确地获取到打印设备的身份标识和打印能力参数，并通过存储模块5可以将打印设备的身份标识和 打印能力参数绑定存储在本地服务器，以便于下次对打印能力参数的调用，这样可以避免每次打印作业时都向打印设备进行打印能力参数的查询，减少了通信交互过程，提高了检索和查询效率，进而能够快速地选择出最优打印设备进行打印操作。
在上述实施例的基础上，继续参考附图10可知，在具体应用时，打印设备的打印能力参数可能会在进行更新操作，此时，为了保证服务器中所存储的打印设备的打印能力参数与实际工作中的打印设备的打印能力参数相一致，可以将接收模块1和处理模块2可以执行下述步骤：
接收模块1，还用于在将打印设备的身份标识与打印设备的打印能力参数进行绑定存储之后，接收打印设备发送的更新请求，更新请求中包括打印设备的身份标识和打印能力更新数据。

本实施例中的接收模块1以及处理模块2所实现方法步骤的具体实现过程以及实现效果与上述实施例中的步骤S301-S302的具体实现过程以及实现效果相同，具体可参考上述陈述内容，在此不再赘述。
在打印设备的打印能力参数存在更新时，通过接收模块1接收更新请求，其中，更新请求中包括打印设备的身份标识和打印能力更新数据，进而处理模块2可以根据身份标识和打印能力更新数据对打印设备的打印能力参数进行更新，有效地保证了服务器中所存储的配置数据与实际应用中打印设备的配置数据相一致，保证了打印设备选择的精确可靠性，进而提高了该服务器使用的稳定可靠性，
在上述实施例的基础上，继续参考附图9可知，在进行目标打印设备的选择过程中，与服务器相连接的多个打印设备的状态可以处于在线状态和离线状态，其中，在线状态是指打印设备可以随时接收服务器所发送的指令，并可以根据用户发送的打印作业进行打印操作；离线状态是指打印设备处于关闭状态或者与服务器信息连接不同的状态，此时，打印设备无法立刻执行相应的打印操作；为了保证目标打印设备可以稳定地满足用户的打印作业，处理模块2还可以用于执行以下步骤：
在确定目标打印设备之后，判断目标打印设备是否处于在线状态；若目标打印设备处于在线状态，则控制目标打印设备根据打印作业进行打印操作；或者，若目标打印设备处于离线状态，则根据用户的检验结果获取目标打印设备的离线原因；根据离线原因判断目标打印设备能否进行打印操作。
进一步的，在处理模块2根据离线原因判断目标打印设备能否进行打印操作时，该处理模块2可以用于：若目标打印设备可以进行打印操作，则控制目标打印设备处于在线状态，并根据打印作业进行打印操作；或者，若目标打印设备无法进行打印操作，则在其他打印设备中重新确定新的目标打印设备。
本实施例中的处理模块2所实现方法步骤的具体实现过程以及实现效果与上述实施例中的步骤S401-S404、S4041-S4042的具体实现过程以及实现效果相同，具体可参考上述陈述内容，在此不再赘述。
在进行目标打印设备的选择过程中，与服务器相连接的多个打印设备的状态可以处于在线状态和离线状态，进而，在确定目标打印设备时，通过处理模块2判断目 标打印设备是否处于在线状态，若处于在线状态，则可以直接执行打印操作；若处于离线状态，则根据用户的检验结果获取离线原因，进一步判断该目标打印设备是否能够执行打印操作，这样有效地实现了在保证目标打印设备可以满足用户的打印作业时，该目标打印设备可以执行打印操作的稳定可靠性，进一步提高了该服务器的实用性。
