具体实施方式
下面结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请实施例的描述中，以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。还应当理解，在本申请以下各实施例中，“至少一个”、“一个或多个”是指一个或两个以上(包含两个)。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。术语“连接”包括直接连接和间接连接，除非另外说明。“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。
在本申请实施例中，“示例性地”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性地”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性地”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请实施例中，“用户”不限定是电子设备的拥有者或某个特定使用者，也可以是动物、硬物或其它物体。用户的对电子设备的操作也可以是动物、硬物或其它物体对电子设备的操作。使用“用户”或者“用户的操作”等词旨在作为示例性的说明，具体是谁执行的该操作，本申请实施例不做限定。
本申请实施例的打印方法可应用于打印系统中。示例性的，如图2示出了本申请实施例的技术方案所适用的打印系统的一种示例。该系统包括第一电子设备100、第二电子设备200以及第三电子设备300。
其中，第一电子设备100可以位于第一网络内。可选的，第一网络可以是任何可以使用的网络。比如，蜂窝网，或无线高保真(wireless fidelity,Wi-Fi)网络。
第一电子设备100中可以安装控制打印任务的应用(可简称为打印应用)，该应用可以通过第三网络与第二电子设备200交互打印协议相关的报文(可简称为打印协议报文，或打印服务报文，或打印报文)。可选的，第一电子设备100可以但不限于是：手机、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、手持计算机、上网本、个人数字助理(personal digital assistant，PDA)等电子设备，本申请实施例对此不做任何限制。
在一些实施例中，第一电子设备100还可以是服务器。
可选的，第三网络包括广域网。可选的，第三网络中可以设置有服务器。服务器与第一电子设备100、第二电子设备200的厂商可以相同，可以不同。在一些示例中， 用户可以对第一电子设备100中的部分数据进行备份，上传到服务器，服务器可以存储这些备份数据。后续，第一电子设备100接收到用户输入的针对目标数据的打印指令时，可以指示服务器将服务器存储的目标数据传递给远程的打印机，以实现打印机的远程打印。在另一些示例中，第一电子设备100接收到用户输入的针对目标数据的打印指令后，将打印数据(比如待打印的图片)发送给第三网络中的服务器，服务器不保存打印数据，而是直接将打印数据通过路由器发送给打印机。可选地，在一些可能的场景中，用于保存用户打印数据的服务器和用于将打印数据通过路由器发送给打印机的服务器可以不同。
可选的，打印协议包括但不限于因特网打印协议/多播域名系统(internet printing protocol/multicast domain name system，IPP/mDNS)。
第二电子设备200、第三电子设备300位于第二网络内。可选的，第二网络可以是任何可以使用的局域网，比如Wi-Fi网络。

第三电子设备300用于通过第二电子设备200接收来自第一电子设备100的打印报文，并根据打印报文执行待打印文件的打印任务。可选的，第三电子设备300为打印机，该打印机可以支持远程打印功能，也可以不支持远程打印功能。
其中，打印机支持远程打印功能，指的是打印机支持直接从打印云获取待打印文件。比如，图1A所示打印场景中，打印机支持远程打印功能，则打印机可以直接从打印云获取待打印文件，之后，打印机执行针对该待打印文件的打印任务。
打印机不支持远程打印功能，指的是打印机不支持直接从打印云获取待打印文件。作为一种解决方案，如图1B，在组网中引入打印云盒，由打印云盒从打印云获取并存储待打印文件，并将待打印文件转发给打印机。其中，打印云盒需要向打印云进行注册，注册方式包括但不限于扫码注册等。如此，导致借助打印云盒实现远程打印的过程中，用户的操作复杂度提升，用户体验不佳。

如下以第一电子设备100为手机，第二电子设备200为路由器，且手机与路由器位于不同局域网为例对本申请实施例的技术方案进行说明。
示例性的，以用于控制打印任务的应用为智慧生活应用为例，响应于用户打开智慧生活应用的操作，手机显示如图5B的(a)所示界面601。其中，界面601包括家中各电子设备的卡片。其中，路由器AA的卡片的标记为602。若检测到用户点击卡片602，则手机可跳转到如图5B的(b)所示界面603。可选的，该界面603可展示路由器AA的接入设备。可选的，界面603还可以包括远程打印选项604。若检测到用户点击远程打印选项604，则手机可跳转到如图5B的(c)所示远程打印界面605。可选的，界面605包括本地照片选项606和本地文档选项607。其中，本地照片选项606用于用户选择待打印的本地照片，本地文档选项607用于用户选择待打印的本地文档。
在一些示例中，若手机检测用户点击如图5B的(c)所示本地照片选项606，则手机可跳转到如图5B的(d)所示相册界面608，用户可以从相册中选择待打印的本地照片。响应于用户选择待打印照片的操作，比如点击如图5B的(d)所示照片后，如图6的(a)所示，手机可跳转到远程打印界面605，并且，手机开始建立与路由器之间的远程通道(比如点到点(peer-to-peer，P2P)通道)。可选的，手机可以显示“正在建立远程通道…”信息609，以提示用户当前正在与路由器建立远程通道。手机建立与路由器之间的远程通道后，可显示如图6的(b)所示界面610。
可选的，该界面可包括提示信息612，以提示用户当前已建立与路由器之间的远程通道。
可选的，界面610还可包括待打印的照片的预览信息611。
可选的，界面610还包括打印功能相关的选项。可选的，打印功能相关的选项包括但不限于：用于选择打印机的选项619，用于选择打印份数的选项，用于选择纸张类型的选项，用于选择打印模式(黑白、彩色打印)的选项，用于选择纸张尺寸的选项。
其中，如图7A的(a)所示，响应于用户点击选项619的操作，手机可显示如图7A的(b)所示打印机选择界面617。若检测到用户在界面617上点击控件618的操作，则手机确定用户想要使用打印机XX执行本次打印任务。检测到用户在界面617上点击控件618的操作后，手机可跳转回如图7A的(a)所示界面610。
可选的，界面610还包括开始打印按钮613。响应于用户点击开始打印按钮613的操作，手机调用系统提供的打印服务，打印服务按照打印协议生成打印报文。手机还可以调用系统提供的VPN接口，以便拦截并向路由器发送该打印报文。打印报文包括打印指令对应的报文以及待打印文件的报文。
路由器接收到该打印报文后，可向连接的打印机转发该打印报文。可选的，打印指令对应的报文可携带如图6的(b)所示一个或多个打印参数。比如，携带打印的份数、纸张类型(普通纸)、打印模式(黑白)、纸张尺寸(A4)。手机可以通过打印报文为打印机设置该一个或多个打印参数。
打印机通过路由器接收到来自手机的打印报文之后，可以根据打印报文执行打印任务。示例性的，打印机根据打印指令对应的报文中携带的打印参数，设置纸张类型等，设置完打印参数后，开始对待打印文件进行打印。
可选的，响应于用户点击如图6的(b)所示开始打印按钮613的操作，如图6的(c)所示，手机可以跳转到远程打印界面605，并显示提示信息614，以便提示用户当前正在执行打印任务。

本申请实施例的上述技术方案中，在接收到用户输入的打印指令之后，手机可以建立与路由器之间的远程通道，并通过该远程通道经由路由器向打印机发送打印指令对应的报文以及待打印文件。如此，打印机能够根据打印指令对应的报文以及待打印文件执行打印任务。可见，在打印机不支持远程打印功能或支持远程打印功能的情况下，打印机均能够通过路由器接收来自手机的打印指令对应的报文以及待打印文件，并执行该打印任务，提升了远程打印任务的执行成功率。
此外，上述技术方案中，在打印机不支持远程打印功能的情况下，手机可以拦截打印报文，并通过路由器向打印机发送拦截的打印报文，该过程中，无需额外引入打印云盒，不仅降低了家庭网络的组网复杂度，还能够避免打印云盒注册导致的高操作复杂度。
需要说明的是，图6中以手机在用户点击“开始打印”按钮613之前建立与路由 器之间的远程通道为例，在另一些实施例中，手机还可以在检测到用户点击“开始打印”按钮613之后建立上述远程通道，本申请实施例并不限制手机建立上述远程通道的时机或触发条件。
示例性的，若检测到用户在如图5B的(d)所示界面608中选择(比如单击)待打印图片的操作，则手机可显示如图7B的(a)所示界面610，该界面包括开始打印按钮613。在检测到用户点击开始打印按钮613后，手机可显示如图7B的(b)所示界面616。可选的，界面616可包括提示信息612，用于提示用户手机当前正在建立远程通道和/或远程通道已建立成功。在远程通道建立成功之后，如图7B的(c)所示，手机可在界面616中显示提示信息614，用于提示用户打印机当前正在打印。待打印机打印完成后，如图7B的(d)所示，手机可在界面616中显示提示信息615，用于提示用户打印机已完成打印。
如下，对打印过程中上述各电子设备之间的交互进行介绍。示例性的，以第一电子设备100为手机，第二电子设备200为路由器，第三电子设备300为打印机，且第一电子设备100、第二电子设备200、第三电子设备300满足图2所示系统架构为例，如图7C所示，本申请实施例提供的打印方法包括：
S101、手机接收用户输入的打印指令。
作为一种可能的实现方式，如图8A，S101可以实现为：S101a、手机通过打印应用接收用户输入的打印指令。打印应用包括但不限于与打印任务相关的智慧生活等应用。
本申请实施例中，用户可以以任何可用方式输入打印指令，该打印指令用于指示手机远程控制打印机执行打印任务。可选的，打印指令可以是用户通过界面输入的指令，也可以是用户输入的语音指令，本申请实施例对打印指令的形式不做限制。
示例性的，用户可以通过语音助手输入语音“让家里的打印机打印手机相册中的图片A”，该语音可以作为打印指令。
再示例性的，如图6的(b)所示，智慧生活应用接收到用户点击“开始打印”按钮613的操作指令，该操作指令可作为打印指令。
S102、手机生成并拦截打印报文。
手机检测到打印指令之后，可以生成打印报文，以便控制远程打印机执行打印任务。打印报文包括打印指令对应的报文(即打印控制报文)以及待打印文件的报文(即打印数据报文)。可选的，一个待打印文件可按照打印协议封装为一个或多个报文。
作为一种可能的实现方式，如图8A所示，S102可以实现为：S102a、打印应用调用手机系统提供的打印服务，S102b、打印服务生成打印报文。之后，打印服务还可以执行步骤S102c、向内核传递该打印报文。在相关技术中，手机可以通过内核向其他设备转发打印报文(比如基于mDNS局域网内的打印协议进行转发)，但是，该转发过程通常限于同一局域网内的转发。也就是说，手机需要与接收设备在同一局域网内。本申请实施例中，为了使得手机能够向远程的设备发送打印报文，手机可以将内核生成的打印报文拦截到打印应用中，并建立打印应用与远程路由器之间的远程通道，如此一来，可以通过打印应用向远程路由器发送打印报文，以便实现远程打印。
作为一种可能的实现方式，如图8A，手机对内核生成的打印报文进行拦截，可以 实现为如下步骤S102d-S102g：
S102d、打印应用调用VPN服务；
S102e、VPN服务向内核发送拦截请求，该拦截请求用于请求拦截打印报文。
内核接收拦截请求后，确定需要将本次打印任务中的一个或多个打印报文发送给VPN服务。那么，此后，当内核从打印服务接收本次打印任务的打印报文后，需要将该打印报文转发给VPN服务。
S102f、内核向VPN服务发送打印报文，VPN服务从内核拦截到打印报文。
作为一种可能的实现方式，内核从打印服务接收某个类型的报文后，可以通过该报文的服务名称(或称包名)识别出该报文是打印报文。之后，内核拦截该打印报文，并将该打印报文发送给VPN服务。
S102g、VPN服务将拦截的打印报文传递到打印应用中。
可选的，VPN服务可以通过相关技术实现。示例性的，对于安装系统的手机，VPN服务可以基于vpnservice接口实现。
需要说明的是，对生成、拦截打印指令的报文，以及生成、拦截待打印文件的报文的执行顺序，本申请实施例不做限制。
S103、手机与路由器之间建立远程通道。
作为一种可能的实现方式，如图8A，S103可以实现为：S103a、手机建立打印应用和路由器之间的远程通道。可选的，该远程通道用于打印应用和路由器之间传输打印报文。
可选的，远程通道包括但不限于是P2P通道。可选的，P2P通道包括但不限于基于会话穿越应用的网络地址转换(session traversal utilities for nat，stun)技术的P2P通道、基于中继穿越的网络地址转换(traversal using relays around nat，turn)技术的P2P通道。
示例性的，若建立基于turn技术的P2P通道，则该P2P通道可以包括用于中继服务的服务器。若建立基于stun技术的P2P通道，则该P2P通道可以不包括用于中继服务的服务器，即手机与路由器之间可以直接连接，手机与路由器之间不存在其他中继节点。
需要说明的是，手机可以在接收用户输入的打印指令之后，建立与路由器之间的远程通道。比如，手机在检测到用户点击如图7B的(a)所示的开始打印按钮613之后，建立远程通道。或者，手机可以在接收用户输入的打印指令之前，预先建立与路由器之间的远程通道。比如，手机在检测到用户点击如图6的(b)所示的开始打印按钮613之前，预先建立远程通道。本申请实施例对远程通道的建立时机与具体建立方式不做限制。
S104、手机通过远程通道向路由器发送打印报文。
作为一种可能的实现方式，如图8A，S104可以实现为：S104a、打印应用通过远程通道向路由器的通信模块发送打印报文。其中，该打印报文是由打印服务拦截到打印应用中的。可选的，若远程通道包括用于中继服务的服务器，则打印应用可以先向服务器发送打印报文，再由服务器(第四电子设备的一个示例)向路由器发送打印报文。
需要说明的是，打印指令的报文与待打印文件的报文，可以通过同一消息发送，也可以通过不同的多个消息发送。对于通过多个消息发送报文的情况，可以先发送打印指令的报文，或者先发送待打印文件的报文，或者，同时发送打印指令的报文以及待打印文件的报文。
示例性的，手机在检测到用户点击如图7B的(a)所示的开始打印按钮613之后，开始向路由器发送打印报文。打印报文包括打印控制报文以及待打印文件的报文。打印控制报文可携带如图7B的(a)所示的一个或多个打印参数(比如但不限于纸张类型、纸张尺寸等)。待打印文件的报文比如可以是如图7B的(a)所示的待打印图片611封装形成的一个或多个报文。
S105、路由器向打印机发送打印报文。
作为一种可能的实现方式，如图8A，S105可以实现为：S105a、通信模块解析并向路由器的VPN服务传递打印报文；S105b、路由器的VPN服务向内核传递打印报文；S105c、内核通过相应驱动调用通信模块向打印机发送打印报文。
可选的，路由器的VPN服务可以基于的tun接口实现。
S106、打印机执行打印任务。
示例性的，如图6的(c)所示，打印机执行打印任务的过程中，手机可显示提示信息614，以提示用户打印机正在打印。
S107、打印机向手机发送响应报文。
其中，该响应报文用于指示已完成打印任务。
作为一种可能的实现方式，打印机通过路由器向手机发送该响应报文。
可选的，由于打印机与路由器在同一局域网内，因此，路由器可以通过内核与打印机进行交互。可选的，路由器与打印机之间的交互流程可以遵循局域网内的打印协议(比如mDNS协议)。
路由器通过内核从打印机接收响应报文(对应图8A所示步骤S107a)后，确定所述响应报文的标识(比如服务名称),并根据所述响应报文的标识向所述第一电子设备发送所述响应报文。示例性的，路由器接收响应报文后，根据响应报文的服务名称，确定响应报文是打印服务的报文，则可以调用VPN服务拦截该响应报文(对应图8A所示步骤S107b),VPN服务将拦截的响应报文传递给通信模块(对应图8A所示步骤S107c)，由通信模块通过上述远程通道将响应报文发送给手机(对应图8A所示步骤S107d)。其中，通信模块与手机之间的交互可以遵循IPP。
示例性的，在打印机执行完打印任务后，可以向手机发送指示信息，手机接收到指示信息后，获知打印机已执行完打印任务，则可以显示如图6的(d)所示的提示信息615，以提示用户打印机已完成打印任务。
上述实施例中，在远程打印场景下，手机通过智慧生活等打印应用和路由器之间建立通道，并通过打印应用和路由器之间传递打印报文(包括打印指令对应的报文、待打印文件的报文)，进而路由器能够将打印报文发送给打印机，实现打印机打印远程文件(即打印不在同一局域网中的设备内的文件)的功能。与图1B所示方案中在打印机不支持远程功能时，需要借助打印云盒才能从打印云接收待打印文件，组网实现较为复杂相比，本申请实施例的技术方案，组网中不再需要额外独立设置的打印云 盒即可实现远程打印功能，降低了组网复杂度。
并且，本申请实施例中，打印报文经由手机、路由器就可以到达打印机，通信路径经过的设备数目更少，传输时延更小，传输效率更高，有助于提升打印任务的效率。
此外，路由器从手机接收打印报文后，可以无需存储打印报文，能够降低存储资源的消耗。
示例性的，如图8B示出了本申请实施例的又一方法流程。在流程中，手机先通过路由器发送打印控制报文，再向打印机发送待打印文件，以控制打印机执行远程打印。如图8B，该方法包括：

可选的，打印机接收打印控制报文后，根据打印控制报文设置打印参数。设置完打印参数后，打印机可以通过路由器向手机发送该第一响应报文，第一响应报文用于表征打印参数已设置完成。
该步骤S406为可选步骤。
S407、手机向打印机发送待打印文件。
在一些实施例中，手机接收来自打印机的第一响应报文后，获知打印机已设置好相应打印参数，则手机向打印机下发待打印文件。
作为一种可能的实现方式，手机经由路由器向打印机发送待打印文件。可选的，若手机与路由器之间的远程通道包括服务器，则手机可以先向服务器发送待打印文件，再由服务器经由路由器向打印机发送待打印文件。
手机向打印机发送待打印文件的流程，可参见手机向打印机发送打印控制报文的流程。手机调用VPN服务对待打印文件进行拦截，并将拦截的待打印文件通过远程通道发送给路由器，由路由器将待打印文件转发给打印机。
S408、打印机执行打印任务。
打印机接收待打印文件之后，执行针对该待打印文件的打印任务。
S409、打印机向手机发送第二响应报文。

本申请实施例对建立远程通道的时机不做限制。服务器可以是在接收打印指令之后建立远程通道，或者，在用户选择待打印的云文件之后，且接收打印指令之前，服务器建立远程通道。或者，在另一些实施例中，在本次打印任务之前，服务器与路由器已经建立过远程通道，则无需为本次打印任务再建立远程通道。
S205、服务器通过远程通道向路由器发送打印报文。
S206、路由器向打印机发送打印报文。
