针式打印机走纸问题

[cqmi2009]

1.针式打印机，型号dpk8300e+
2.纸张ABC 24.1*9.3，已全部设置OK
3.打印机首选项中纸张已设为ABC
4.测试程序：

dim i as long
for i=1 to 5
printer.newpage
next

5.结果
打印机走纸5页短2.5厘米

改如何调整，或该用什么方法控制打印机走纸？

[msdtx]

给用户一个走纸修正的参数设置，通过这个校正值走一段空白距离。
不过这样做还不够，还需要一个输出点，我自己把它叫做定位点，让打印机打印出这个点。这仅是我的经验。

这个想法是好的，我试过在纸张的最下边打印一条横线，但这条横线打出来后距离纸张最下边有0.5厘米的距离，你说的校正值走一段空白距离如何实现呢？

越说越离谱了。
开始还是0.5毫米，现在成了0.5厘米了。

任何计量工具都是有误差的，0.5毫米是肉眼估计的吧。
假定你的纸张尺寸是精确的，可能此类打印机走纸长度的测量有误差，
a)在打印机设置中纸张长度加长0.5毫米；
b)某些打印机上有微调按钮，手工调整一下。

LZ的5毫米=0.5厘米

压根都没有出现过0.5毫米！

每页少走0.5厘米，把纸张定义的高度增加0.5厘米后第一页刚好走完，打第二页时直接走两页纸！

[cqmi2009]

是的，现在用的是LQ1600的驱动，由于打印机比较老了，微调功能不大好使了。现在采取了每页EndDoc一下后再直接向LPT端口写个进纸5毫米的命令，问题基本解决了。

多谢各位热心的朋友！

也只能是这么处理了.

用程序不好，可以直接在控制面板的打印机设置里添加一个自定义纸张类型，不需要程序控制打印机走纸。

调整自定义纸张的大小应该可以

[Tiger_Zhao]

微调不是常用功能，难道你换的4台针式打印都坏了？
如果再买一台新的打印机，新旧混用怎么办？
硬件不好就修一下。

理论上可行，实际操作过，完全不行，如果自定义的纸张高度大于实际纸张高度的话，进第一页纸还可以，后面就乱套了，一会走两页，一会走一页！

[Tiger_Zhao]

1)26楼说得不错，你用 1600K 的驱动试试。
2)不停调整页面设置的高度，用连打11页的方式测试实际走纸高度，使得逐渐接近到 9.3 厘米。

[cqmi2009]

连打11页，然后测量首尾两页相同位置（文本行）之间的距离，除10就是打印机的走纸高度，与页面设置比较，进行调整。

按你说的做了，得出的走纸高度是8.9厘米。
页面设置如下：
宽度 24.1cm
高度 9.3cm
上下左右边距都是0cm

请问如何调整纸张？

打印机和窗体的打印定位方法都是一样的，用CurrentX,CurrentY定位啊。
另：执行 EndDoc 后打印机确实会按它自己的方式再走一段保留距离（不可打印的边界），但可以肯定同一打印机同一纸型其保留距离是一定值。

[msdtx]

用自定义纸张可能不管用，如果您的客户拿尺子量好纸张设置到系统中，但打印出来的结果还是不对，他是骂卖骚公司呢还是骂你呢？
页末用CurrentX,CurrentY 定位，PSet打一个定位点标记（好自己用尺子量），再EndDoc。

[Obj_GetFile]

1、你的纸张不是标准的纸张，打印机不一定支持。
2、需要知道打印机的无法打印区域，根据这个区域，确定页边距。
3、设置自定义纸张。

如何在 Windows NT 和 Windows 2000 中使用自定义页面大小打印
文章编号:282474
最后修改:2004年3月25日
修订:1.2
概要
在 Microsoft Windows 95、Windows 98 和 Windows Millennium Edition (Me) 系统上，可以灵活地自定义页面大小。但在运行 Windows NT 和 Windows 2000 的系统上，必须先将所有页面大小定义为页形 (form) 才能使用。本文介绍如何在 Windows NT 和 Windows 2000 上打印自定义页面大小，并包含一个代码示例，演示如何添加、选择和删除自定义页形。

我现在也遇到了你说的刚开始的问题，
我在页面的最低端打印一条横线，结果是横线离纸张最下端有5毫米的距离。
连续打印5张后横线离纸张最下端已经2.5厘米了
请教你现在的办法
主要是代码怎么写啊 、
不胜感谢，现在我的打印机还在用手拧呢
麻烦死了

很说明问题了: 你设的纸张长度不精确. 测量和设定纸张长度是非常重要的,特别是对于票据类连续走纸的打印. 科学的做法是拿没有打印过的连续的新纸张,测量多张纸的总长度,再除以张数. 比如你量一下10张连续的新纸总长度,测量到的结果除以10,基本就正确了. 至少连续打几百张是不会有问题的.

我也遇到同样的问题，我的打印机型号是爱普生LQ-2680K，我发现我使用用户自定义纸张用链式纸打印时候，似乎没有效果，每次似乎走的是A4纸的高度，真是郁闷~期待高手指点~
