开机启动完kde后，桌面中间总显示“打印错误”的窗口(已解决)

提示“没有默认打印机”，需要“kjobviewer -all"，做了以后就完全正常了

－－－－－
好几天了，每次启动都如此。

首先看日志：
message
hp: unable to open /var/run/hpiod.port: No such file or directory: prnt/hpijs/hplip_api.c 75

error_log

不知道该如何着手解决？（以前出现过，重装打印机就可以了。现在不想重装，用linux还是尽量不重装了)

请教大家,谢谢

已经解决，原因是spool/内的项目太多了(>100)
一方面，修改cups.conf，另一方面rm spool/*
