技术领域
本申请涉及数码打印技术领域，尤其涉及一种Onepass系统喷墨打印控制方法、设备及存储介质。
背景技术
随着计算机在图形或文字处理上的广泛应用，打印机的应用也变得越来越 普遍，通过打印机，人们可以很方便的将计算机中的文字或图形输出到图片上。目前喷墨打印方式主要分为：多pass打印和Onepass打印。多pass打印的特点是喷头的喷嘴长度方向和打印介质的移动方向Y向平行，喷头在X方向往复运动，打印介质的运动是步进运动，喷头在X方向移动一个行程并完成一个pass的打印，打印介质在喷头换向升速的间歇期步进一pass的距离，喷头反向后完成下一个pass的打印，如此反复完成全部打印操作，打印介质同一位置的图案需要分为多个pass完成。多pass打印效率低、产量小，但其价格便宜，适用于小批量、间歇式生产。所谓的Onepass打印就是喷头喷嘴的长度方向(X方向)与打印介质的移动方向(Y方向)垂直，喷头一般为固定不动，打印介质从喷头下方通过一次就可以得到需要打印的图案，其打印介质连续运动，没有停顿。Onepass打印具有效率高，产量大的优点，适用于大批量、连续生产方式。
技术问题
请参阅图1，现有的Onepass打印设备是由一排喷头首尾拼接组成，当产品沿喷头方向的宽度与所有喷头的宽度总和相等时，一次打印喷头的利用率几乎可以达到100％；然而当产品沿喷头方向的宽度很小时，如产品沿喷头方向的宽度等于一个喷头的宽度，此时只有一个喷头出墨，其他喷头都不出墨，这样打印时喷头的利用率低，资源浪费严重；如果将Onepass打印设备的一排喷头分成多条生产线，如图1中所示，每次打印时每个打印模组都打印独立的打印任务，此时几乎每个喷头都会出墨，可以大大提高喷头的利用率，同时也提高了产品的生产率，其中，每个打印模组可以同时出墨，也可以不同时出墨，各生产线之间相互独立，如何保证打印时每个打印模组支持独立控制的打印任务是Onepass多生产线打印亟待解决的一个问题。

请参见图2，本申请实施例提供了一种Onepass系统喷墨打印控制方法，所述方法依据打印要求指令将所有物理通道划分为若干组，将一组定义为一个打印模组，并为每个打印模组配置n个逻辑通道，然后以逻辑通道为桥梁进行数据的提取及处理，保证了每个打印模组可以独立控制相应的打印任务并能够准 确的打印在预定的位置上。所述方法具体包括如下步骤：
S1、依据打印要求指令将所有物理通道划分为若干组，定义一组为一个打印模组，每个打印模组包括x个物理通道，x≥1，x为整数；
S2、为每个打印模组配置n个逻辑通道，n≥x，n为整数；
S3、启动打印命令，以所述逻辑通道为单位从打印内存中提取对应的打印数据；
S4、依据打印参数将所述打印数据处理后输入对应的物理通道进行打印。
具体的，依据客户输入的打印要求指令将所有物理通道划分为若干组，定义一组为一个打印模组，每个打印模组包括x个物理通道，x≥1，x为整数，其中，当一个所述打印模组仅占据某一个物理通道的一半时，在本申请中当作一个物理通道处理，如一个所述打印模组实际占据3个半的物理通道，则在本申请中所述打印模组包括4个物理通道；根据每个打印模组拥有的所述物理通道个数为每个打印模组配置n个逻辑通道，其中，每个打印模组拥有的逻辑通道的个数可以和其拥有的物理通道的个数相同，则此时一个物理通道对应一个逻辑通道，通过建立打印模组、逻辑通道、物理通道三者之间的对应关系后就可以准确的将以逻辑通道为单位从打印内存中提取的对应打印数据处理后输入对应打印模组中的对应物理通道了。当每个打印模组拥有的逻辑通道的个数大于其拥有的物理通道的个数时，则必然存在某个物理通道对应多个逻辑通道或某个逻辑通道没有对应物理通道，当某个物理通道对应多个逻辑通道时，以所述逻辑通道为单位从打印内存中提取对应的打印数据后将该物理通道中的所有逻辑通道对应的打印数据进行合并，然后再依据打印参数进行处理输入该物理通道；而当某个逻辑通道没有对应的物理通道时，则该逻辑通道不进行任何操作。其中，所述打印参数是根据所述打印要求指令和打印设备特征生成的，具体包括：物理通道对应的喷嘴个数、最大通道数、每个打印模组中的最后通道序号及通道控制参数等一系列和打印相关的参数，每个打印模组包括的物理通道可以位于一台Onepass打印设备，也可以位于多台Onepass打印设备，具体情况在此不再限定。
请参阅图3，在本实施例中，各打印模组位于同一个Onepass打印设备，一个喷头对应一个物理通道，物理通道的数量与逻辑通道的数量相等，一个物理通道对应一个逻辑通道，没有任何两个打印模组共用一个物理通道，该打印设备共有12个喷头既12个物理通道，按照喷头排列的方向(X轴方向)的某一端点为起点对每个物理通道进行编号，垂直与喷头排列的方向为打印方向(Y轴方向)，在本实施例以最左端为起点，每个物理通道的编号从PCH0～PCH11，PCH0表示第一个物理通道，PCH1表示第二个物理通道，PCH3表示第三个物理通道……PCH11表示第十二个物理通道。依据所述物理通道的个数分配12个逻辑通道，并对12个逻辑通道进行编号从LCH0～LCH11，LCH0表示第一个逻辑通道，LCH1表示第二个逻辑通道……LCH11表示第十二个逻辑通道，且第一个逻辑通道LCH0对应第一个物理通道PCH0，且第二个逻辑通道LCH1对应第二个物理通道PCH1，以此类推。根据每个所述物理通道对应的打印模组确定与每个所述物理通道对应的所述逻辑通道对应的打印模组，如本实施例中，物理通道PCH0～PCH2属于打印模组1，则逻辑通道LCH0～LCH2属于打印模组1；物理通道PCH3～PCH6属于打印模组2，则逻辑通道LCH3～LCH6属于打印模组2；物理通道PCH7属于打印模组3，则逻辑通道LCH7属于打印模组3；物理通道PCH8～PCH11属于打印模组4，则逻辑通道LCH8～LCH11属于打印模组4；通过对每个所述物理通道和每个所述逻辑通道进行编号，依据编号可以确定每个所述逻辑通道对应的打印模组及每个所述逻辑通道在所属对应打印模组中的相对位置，每个所述逻辑通道对应的数据长度，且所述逻辑通道对应的数据长度等于物理通道的长度，所述物理通道的长度表示物理通道拥有的喷嘴数量，其中，所述逻辑通道的数据长度也可以大于物理通道的长度。依据上述方法建立了物理通道、逻辑通道、打印模组之间的对应关系，保证了物理通道、逻辑通道、打印模组之间的一一对应关系，进而保证了每个打印模组独立控制。
在另一实施例中,各打印模组位于同一个Onepass打印设备，一个喷头对应一个物理通道，逻辑通道的数量大于物理通道的数量，且存在至少两个打印模组共用一个物理通道，请参阅图4，则为每个所述打印模组配置所述逻辑通道的 方法为：
S211、根据打印要求确认所有物理通道中的共用物理通道和专用物理通道，所述共用物理通道属于y个打印模组，所述专用物理通道仅属于一个打印模组，y≥2，y为整数；
S212、为每个所述共用物理通道配置m个逻辑通道，为每个所述专用物理通道配置z个逻辑通道，m≥y，z≥1，m、z为整数。
具体的，根据打印要求确认所有物理通道中的共用物理通道和专用物理通道，为共用物理通道配置的逻辑通道个数大于等于其属于的打印模组个数，专用物理通道至少配置1个逻辑通道，在本实施例中打印设备共有12个喷头既12个物理通道，按照喷头排列的方向(X轴方向)的某一端点为起点对每个物理通道进行编号，垂直与喷头排列的方向为打印方向(Y轴方向)，在本实施例中以喷头排列方向的最左端为起点，每个物理通道的编号从PCH0～PCH11，PCH0表示第一个物理通道，PCH1表示第二个物理通道，PCH2表示第三个物理通道……PCH11表示第十二个物理通道。逻辑通道的数量大于物理通道的数量，在本实施例中，有4条打印模组，则逻辑通道的数量是物理通道的数量的4倍，则共分配48个逻辑通道，并对48个逻辑通道进行编号从LCH0～LCH47，LCH0表示第一个逻辑通道，LCH1表示第二个逻辑通道……LCH47表示第四十八个逻辑通道，则逻辑通道LCH0～LCH11属于打印模组1，则逻辑通道LCH12～LCH23属于打印模组2，则逻辑通道LCH24～LCH35属于打印模组3，则逻辑通道LCH36～LCH47属于打印模组4；通过对每个所述物理通道和每个所述逻辑通道进行编号，依据编号可以确定每个所述逻辑通道对应的打印模组及每个所述逻辑通道在所属对应打印模组中的相对位置，每个所述逻辑通道对应的数据长度，且所述逻辑通道对应的数据长度等于物理通道的长度，所述物理通道的长度表示物理通道拥有的喷嘴数量。本实施例针对当有打印模组共用物理通道时，通过为每个物理通道配置若干个逻辑通道，然后将若干个逻辑通道按照任务参数分配到不同的打印模组，进而将共用物理通道拆分到不同的打印模组，保证了各打印模组独立控制。
优选的，所述打印要求指令包括：待打印产品沿喷头排列方向的宽度指令，所述依据打印要求指令将所有物理通道划分为若干组包括：
依据所述待打印产品沿喷头排列方向的宽度指令将待打印设备中的所有物理通道划分为若干组，如存在3份待打印产品，第一份待打印产品需要2个物理通道打印，第2份待打印产品需要5.5个物理通道打印，第3份待打印产品需要3个物理通道打印，则将所有物理通道按照2：6：3分配成三份分别对应3份待打印产品，每一份为一个打印模组，所述打印模组根据客户需求灵活配置，应用方便。
优选地，所述打印要求指令还包括：待打印产品需要打印的份数指令；则请参阅图5，在所述步骤S2后，所述方法还包括：
S01、根据待打印产品需要打印的份数指令，生成打印任务队列，一个打印模组对应一个打印任务队列；
S02、从每个所述打印模组对应的所述打印任务队列中获取目标打印任务及打印参数；
S03、将每个打印模组的所述目标打印任务存储至任务处理缓存器中的对应存储区域；
S04、依据所述打印要求指令建立物理通道、逻辑通道、打印模组、存储区域四者之间的映射关系。
具体的，请参阅图6，在本实施例中，根据待打印产品沿喷头排列方向的宽度将所有物理通道分为4组分别为打印模组1、打印模组2、打印模组3、打印模组4，则根据待打印产品需要打印的份数分别为打印模组1、打印模组2、打印模组3、打印模组4生成一个打印任务队列，四个打印模组的打印任务队列中包含的打印任务数相同，在本实施例中打印模组1的打印任务队列目前只有1个任务队列即图6中的背景图像的任务队列，打印模组2的打印任务队列有若干个即图6中的日期任务队列如“2018年10月1日、2018年10月2日、2018年10月3日……”，打印模组3的打印任务队列有若干个即图6中的天气任务队列如“雨天、多云、晴天……”，打印模组4的打印任务队列有若干个即图6 中的条码任务队列如“100000、100001、100002……”；然后每个打印模组依据打印任务队列的先后顺序依次读取对应的打印参数，读取打印参数的同时建立目标打印任务，目标打印任务建立完成后将其存储至任务处理缓存器中的某一存储区域，在所述任务处理缓存器中每个打印模组都有一个对应的目标打印任务存储区域，最后根据打印要求指令建立物理通道、逻辑通道、打印模组、存储区域四者之间的映射关系，使得四者之间相互联系，同时也保证了每个打印模组的独立控制，启动打印命令后，依据映射关系就可以方便快捷且准确的将以所述逻辑通道为单位从打印内存中提取的对应打印数据进行处理后输入对应的物理通道进行打印。
优选地，请参阅图7，在本实施例中，所述步骤S3：启动打印命令，以所述逻辑通道为单位从打印内存中提取对应的打印数据具体包括：
S31、启动打印命令，依据所述映射关系从所述任务处理缓存器中提取每个打印模组的所述目标打印任务；
S32、根据所述目标打印任务的打印参数计算本次点火所述逻辑通道对应的打印数据的存储地址，依据所述存储地址从打印内存中提取对应的打印数据。
请参阅图8，在本实施例中，所述步骤S32：根据所述目标打印任务的打印参数计算本次点火所述逻辑通道对应的打印数据的存储地址，依据所述存储地址从打印内存中提取对应的打印数据具体包括：
S321、获取本次点火所述逻辑通道的逻辑通道编号及逻辑通道参数；
S322、获取目标打印任务的打印任务编号，依据所述打印任务编号获取目标打印任务对应的任务参数及目标打印任务的打印位置；
S323、依据所述逻辑通道参数、所述目标打印任务对应的所述任务参数及所述打印位置获得所述逻辑通道对应的通道数据的存储地址及打印参数；
S324、依据所述存储地址从打印内存中提取所述通道数据，并将所述通道数据与所述打印参数进行处理获得打印数据。
请参阅图9，具体到某一次打印中，需要首先获取逻辑通道编号，获取逻辑通道编号的同时获取其对应的逻辑通道参数和该逻辑通道的目标打印任务编 号；根据目标打印任务编号同时获取任务参数、任务的打印位置，然后通过逻辑通道参数、所述目标打印任务对应的所述任务参数及所述打印位置计算就可以获得逻辑通道对应的通道数据在打印内存中的存储地址和打印参数，根据存储地址就可以正确无误的从打印内存中提取到通道数据，将所述通道数据依据所述打印参数进行数据处理得到打印数据后，根据逻辑通道与物理通道的映射关系能够准确的将打印数据输入到物理通道进行喷墨打印。其中，所述任务参数包括目标打印任务对应的打印目标图像的打印尺寸，根据每个打印目标图像的尺寸确定其打印过程中需要用到的物理通道个数及物理通道位置，然后根据物理通道的个数为打印任务配置所述逻辑通道，且根据物理通道位置确定每个所述逻辑通道之间的相对位置等逻辑通道参数，则所述逻辑通道参数包括通道偏移、通道使能及通道插点数，所述通道偏移用于判断对应的通道在目标打印任务中是否工作，所述通道插点数具体用于计算其对应的数据在内存中的存储地址，即对于某一个打印任务的逻辑通道对应的通道数据地址为：通道插点数x逻辑通道对应的数据长度+当前打印行的起始数据地址。在另一实施例中，通过目标打印图像的打印尺寸、起始像素点及结束像素点和插接喷头数以及所有物理通道的喷嘴列数；通过像素平面坐标系将目标打印图像的Onepass打印数据与物理通道、插接喷头数、所有物理通道的喷嘴列数等关联起来，然后结合图像特征、Onepass打印技术特点确定了目标打印图像在打印时需要屏蔽的图像数据的屏蔽信息，根据屏蔽信息就可通过对物理通道的喷嘴列进行控制使其不出墨，从而实现对目标打印图像的部分图像数据进行精准屏蔽处理，满足了不同用户的打印需求。
所述打印位置包括所述目标打印任务相对于打印平台在第一方向的坐标值及在垂直于第一方向的第二方向的目标打印坐标值，当所有逻辑通道完成一次数据读取后所述目标打印任务的目标打印坐标值加1。具体的，请参阅图10，目标任务参数中的打印目标图像F的打印尺寸为沿喷头排列方向(x方向)上两个喷头的长度，在本实例中定义一个喷头可以打印300个像素(即一个喷头拥有的喷嘴数量为300)，沿垂直喷头排列的方向(y方向)为一个喷头的长度， 具体打印位置为第3个喷头到第4个喷头的位置。以一个物理通道对应一个喷头为例，当为每个物理通道配置一个逻辑通道时，则逻辑通道PCH0在x轴方向的通道偏移量为0个喷头的距离即没有偏移，则逻辑通道PCH1在x轴方向的通道偏移量为1个喷头的距离即300个像素，则逻辑通道PCH2在x轴方向的通道偏移量为2个喷头的距离即600个像素，依次类推得到每个逻辑通道的在x轴方向的通道偏移量。打印图像经过图像光栅处理器处理后是按照原始数据进行排列的即720x720DPI的图像每一列每一行的每英寸都需要打印720个像素点，但实际喷头只有360个喷嘴即一次最多打印360个像素，而要打印720个像素需要进行两次打印，所以需要将数据进行拆分，为了使数据打印均匀720像素点交错分成两份并进行插点编号即每一份都有一个插点数，而以所述逻辑通道进行数据提取时需要改所述逻辑通道的通道插点数即该逻辑通道需要提取那一份通道数据进行可以准确的计算出数据存储的地址。所述打印位置是目标图像相对打印平台具体打印的准确坐标值，这样就使打印设备明确的知道该目标图像的具体打印位置了，如图3，打印位置中的当前打印任务相对于打印平台在第一方向(X方向)的坐标值为600个像素，在垂直于第一方向的第二方向(Y方向)的当前打印坐标值的范围是300个像素到600个像素，当所有逻辑通道完成一次数据读取后所述当前打印任务的所述当前打印坐标值加1，所述当前打印坐标值就是打印设备Y轴累加器的值，所述Y轴累加器同打印设备Y方向的光栅连接，根据光栅获取具体位置计数。
其中，请参阅图11，所述步骤S323包括如下步骤：
S3231、根据所述目标打印任务的打印参数计算本次点火所述逻辑通道对应的打印数据的实际存储地址；
S3232、根据所述目标打印任务的打印参数和内存寻址要求确定所述逻辑通道对应的打印数据的要求读取地址；
S3233、依据所述实际存储地址和所述要求读取地址，确定待读取的所述打印数据中的无效数据；
S3234、读取所述打印数据，将所述无效数据去掉后写入数据缓存中。
具体的，在本实施例中打印数据的提取都要求以字节的整数倍对齐，如64bit、56bit等，但实际存储的打印数据存在不对齐的情况，因此读取打印数据时需要进行对齐操作，根据打印参数可以计算出本次点火所述逻辑通道对应的打印数据的实际存储地址，然后再根据内存寻址要求确定所述逻辑通道对应的打印数据的要求读取地址，则所述要求读取地址到所述实际存储地址范围内存储的数据就是打印数据中的无效数据，最后读取打印数据，将所述无效数据去掉后写入数据缓存中，此时数据缓存中的打印数据都是以字节的整数倍对齐的。
优选地，所述打印数据处理包括：屏蔽处理、羽化处理、合并处理。具体的依据打印参数将数据缓存中的打印数据同根据打印要求确定的数据进行相关计算，如待打印产品沿喷头排列方向的宽度小于打印设备的最大打印宽度时就会存在部分物理通道不出墨，则此时就需要对其进行屏蔽处理，对于物理通道拼接的部分为了保证其打印效果可能需要羽化处理，使得数据被分成两部分分别由两个物理通道而不会存在重复。请参阅图12，当存在共用物理通道时，则共用物理通道的多份数据需要合并后再进行打印，具体包括如下步骤：

优选地，请参阅图16，结合所述逻辑通道，将所述背景图像数据和每次获取的标签图像数据按照预定排版规律融合后输入对应的物理通道进行喷墨打印具体包括如下步骤：

各所述打印模组独立控制后，则怎样保证一幅可变图像中的背景图像和每个标签图像能够匹配打印，则需要一套独特的打印任务创建方法，优选地，请参阅图17，则各模组同步创建打印任务的方法具体包括如下步骤：
S51、获取背景模组的触发打印信号，依据所述触发打印信号判断所有模组对应的打印任务队列是否为空；
S52、当所有模组对应的所述打印任务队列不为空时，则判断每个所述打印任务队列中当前打印任务的任务参数读取是否有误；
S53、当所有模组的所述任务参数读取无误时，则控制所有模组同时创建本次打印任务。
具体的，每个所述打印模组都有一个触发打印模块，用于触发各打印模组创建自己的打印任务，当各打印模组打印的图像有关联时，则采用同一个触发打印信号去触发各打印模组进行打印任务的创建，保证了各打印模组相互关联，在本实施例中采用背景模组的触发打印信号作为触发各模组创建打印任务的统一信号。
优选地，所述背景模组的触发打印信号为外部光眼产生的有效信号或上一次打印任务的结束信号。采用外部光眼产生的有效信号需要增加额外设备，采用上一次打印任务的结束信号作为触发打印信号则需要明确打印任务的结束时间，通过设置任务间隔确定明确的结束信号。
具体的，请参阅图18为本实施例的具体实现流程，首先从上位机获取可变图像对应的数据，所述可变图像中的每一幅都包括一个背景图像0和x个标签 图像(1～x)，所述数据包括固定不变的背景图像数据和按照规律动态变化的标签图像数据，将所述数据存储入存储器的同时缓存任务到对应模组，其中所述任务包括背景模组0的打印任务和标签模组(1～x)的打印任务，然后依据触发信号对缓存的打印任务进行任务创建，创建好后存入对应的模组的打印任务队列，然后打印控制依据每个模组的打印任务队列中的图像数据的存储地址提取数据进行羽化、屏蔽、合并处理中的一种或多种后输入打印模块进行打印。具体的对于某一次的打印某些物理通道需要出墨而某些物理通道不需要出墨，而不需要出墨的物理通道依据其对应的逻辑通道提取的数据需要做屏蔽处理使其不出墨；对于某些图像需要较高的打印质量时，则一般在打印时对该图像做羽化处理使其打印效果更好，具体操作为将图像对应的打印数据同羽化模板数据进行相“与”运算使得打印出来的图像效果更好；在打印可变图像时，一类可变图像中的每一幅图像都有一个相同的背景图像，且在每一幅图像的相同位置都有按照一定规律变化的可变图像，当打印这一类图像时，需要将对应同一个物理通道的背景图像数据和可变图像数据进行合并使其仅打印可变图像数据。
本实施例通过分别获取可变图像中固定不变的背景图像对应的背景图像数据和按照预定规律动态变化的标签图像对应的标签图像数据，将固定不变的背景图像和动态变化的标签图像分开处理和传输，且背景图像数据可以只传输一次，由此背景图像也可以只进行一次图像光栅化处理，减轻了图像光栅化处理器的数据处理量和传输量，然后将背景图像数据与每次获取的标签图像数据按照预定排版规律融合后再进行打印，通过融合保证了产品的正常输出，提高了打印机的效率、节省了打印机的资源。

S432、比较所述第一计数值是否等于打印起始位置设定值；
具体的，打印介质每移动一行即所述第一计数器的第一计数值加1后都与所述打印起始位置设定值进行一次比较，判断是否到达起始打印位置，当所述第一计数值等于打印起始位置设定值时，则开始创建本次打印任务，当所述第一计数值大于打印起始位置设定值时，则本次打印任务已经开始，这样可以停止所述第一计数器的计数，也可以继续所述第一计数器的计数，然后将所述第一计数器的计数值同所述第二计数器的计数值进行比较用于验证及校准所述第二计数器。其中所述打印起始位置设定值是根据所述打印精度将客户设置的白边值换算成需要空白的打印行数，进而获取所述第一计数器的计数信号。

S434、创建本次打印任务，并获取对本次打印任务的打印行数进行计数后的第二计数值；
具体的，根据触发打印信号创建本次打印任务，当本次打印任务创建成功后则启动所述第二计数器开始进行计数。当存在多个打印模组时，则还需要判断所有模组是否成功创建本次打印任务，则请参阅图21，多个打印模组同步创建打印任务的判断步骤如下：
S4331、根据触发打印信号判断所有模组是否满足本次创建打印任务的条件；
S4332、当存在一个模组不满足本次创建打印任务的条件时，控制所有模组放弃本次打印任务的创建，重新获取所述触发打印信号；
S4333、当所有模组都满足本次创建打印任务的条件时，控制所有模组创建本次打印任务。
具体的，在本实施例中每个打印模组都有一个独立的触发打印信号，以保证每个打印模组能够独立触发创建打印任务，为了保证每个打印模组能够同时创建打印任务，本申请中采用所有打印模组中的某一个打印模组的触发打印信号作为所有打印模组创建打印任务的请求信号，依据同一个所述触发打印信号判断所有打印模组是否满足本次创建打印任务的条件，如果所有打印模组都满足本次创建打印任务的条件时，则控制所有打印模组创建本次打印任务，当存在一个打印模组不满足本次创建打印任务的条件时，控制所有打印模组放弃本次打印任务的创建，然后返回步骤S4331，如此保证了每个打印模组顺序创建打 印任务，不会因为某一打印模组创建打印任务失败而导致各打印模组打印的标签不匹配。
优选地，请参阅图22，所述第二计数器的第二计数值的具体获取步骤如下：
S4341、获取本次打印任务的打印精度；
S4342、依据所述打印精度获取本次打印任务打印每行像素的点火信号；
S4343、依据所述点火信号进行计数，每点火一次所述第二计数值加1。
具体的，根据本次打印任务的打印精度获取打印每行像素的点火信号，每点火一次所述第二计数器的所述第二计数值加1，所述第二计数器的第二计数值每加1一次后都将所有逻辑通道的通道偏移值与所述第二计数值进行比较，如果所述逻辑通道偏移值小于等于所述第二计数值，则所述逻辑通道执行本次打印任务，否则，所述逻辑通道不执行本次打印任务的打印。
S435、比较每个逻辑通道的通道偏移值是否小于等于所述第二计数值；

S436、当所述逻辑通道的所述通道偏移值小于等于所述第二计数值时，则所述逻辑通道执行本次打印任务的打印，否则，所述逻辑通道不执行本次打印任务的打印；
具体的，当所述逻辑通道的所述通道偏移值小于等于所述第二计数值时，以所述逻辑通道为单位从存储介质中提取的打印数据为有效数据，则所述逻辑通道对应的所述物理通道依据所述有效数据进行喷墨打印；

将所述无效数据存入所述逻辑通道对应的RAM缓存中；
依据所述映射关系从所述RAM缓存中提取所述无效数据到所述物理通道进行打印，其中，当打印数据为无效数据时，所述物理通道在打印过程中不出墨。
根据以上方法则可以实现每个物理通道打印对齐即打印在一条直线上，具体如下图23为所述Onepass喷墨打印机的喷头结构，在本实施例中一个喷头对应一个物理通道，一个物理通道配置一个逻辑通道，则第一个喷头100的通道偏移值为0，第二个喷头200的通道偏移值为1，需要打印的图像数据如图24，当本次打印任务创建完成之后，所述第二计数器开始计数，每点火一次走一行像素的距离，所述第二计数器的第二计数值加+1；当所述第二计数器的计数值为0时，第一个喷头100开始打印第一行像素的a0、a2、a4、a6像素点，第二个喷头200不打印；所述第二计数器的计数值为1时，第一个喷头100打第二行像素的b0、b2、b4、b6像素点，第二个喷头200打第一行像素的a1、a3、a5、a7像素点；第二计数器的计数值为3时，第一个喷头100打印第三行像素的c0、c2、c4、c6像素点，第二个喷头200打印第二行像素的b1、b3、b5、b7像素点；依次类推，直到打完目标图像为止。这样就可以保证所述第一喷头100与所述第二喷头200能够打印对齐，可以打印在同一直线上。
S437、重复比较每个所述逻辑通道的所述通道偏移值是否小于等于所述第二计数值，直到本次打印任务打印完成。
所述方法通过第一计数器对空白位置进行统计记录，并通过比较第一计数值和打印起始位置设定值确定起始打印位置，保证了在Onepass高速打印过程中准确的记录并获得起始打印位置的信息，然后通过创建本次打印任务，及采用第二计数器和每个逻辑通道的偏移值明确每个通道的起始出墨时刻，从而保证了每个逻辑通道对应的数据都可以打印对齐。
