杯子拒绝打印带有“过滤器错误”的pdf文件，因为过长的标题

Question

我的系统是Debian 3.16.7。今天，我使用杯子向我的Kyocera fs-1041打印机渲染了一份打印作业（纸张名称​​单词和短语的分布式表示及其组合性）。但是，打印机拒绝打印，并在杯子的浏览器控制面板上显示“过滤失败”错误消息。

在我的/ var / cups / error_log中，它说：

已搜索过this或this等几个问题和问题，我仍然无法找到解决此问题的方法。

奇怪的是，现在仍然可以打印由LibreOffice等创建的杯子测试页面或doc文件。

所以我想这可能是由pdf文件本身引起的，并开始破解格式化文件，最后意识到一个太长的/Title字段会导致这个问题。在将这个字段从“单词和短语的分布式表示及其组合性”改为“测试”之后，它确实有效!!

但是仍然不知道为什么这个长/Title字段会导致过滤错误，有人可以建议一个答案或者给我一个关于过滤器如何用pdf文件表现的链接吗？

Answer 1

为了修复它，您需要打开打印机文本编辑器的PPD文件。 找到一行*cupsFilter: "application/vnd.cups-raster 0 /usr/lib/cups/filter/rastertokpsl"，然后将rastertokpsl更改为rastertokpsl-fixed。之后，将其保存并打开终端。 在终端中输入sudo nano /usr/lib/cups/filter/rastertokpsl-fixed，然后按Enter。

将此内容粘贴到：

#!/bin/bash
jobname=$(echo $3 | egrep -o '[[:alnum:]]' | tr -d '\n' | tail -c 20)
path=/usr/lib/cups/filter
$path/rastertokpsl "$1" "$2" "$jobname" "$4" "$5"

，然后按Ctrl + O。现在，您可以使用此PPD在“设置”中设置打印机。
