samba3+cups共享打印机失败，help.

Finale

系统是fb6.1, 打印机是epson 1100，kernel已找到打印机设备。cups已安装启动，smb.conf加了cups选项。

[global]
...
        load printers = yes
        printing = cups
        printcap name = cups
        cups options = raw

[printers]
        comment = All Printers
        path = /var/spool/samba
        browseable = no
        public = Yes
        guest ok = Yes
        writable = No
        printable = Yes
        use client driver = yes  


我参照的是这里的配置，使用raw打印，cups安装raw设备驱动。

http://www.linuxprinting.org/kpf ... 1th-draft.html#14_4

但安装好raw设备后启动打印机无法打印测试页, cups log显示

E [29/Aug/2006:13:56:41 +0800] [Job 16] Unable to open USB device "usb:/dev/unlpt0": Permission denied
I [29/Aug/2006:13:56:41 +0800] [Job 16] Backend returned status 1 (failed)

这是怎么回事呢？怎么会permission denied?

发现只要发送一个测试页，cups打印机马上转为stopped状态，而且无法start. 删除job以后又可以start了，无法打印。。。

Finale

从windows可以发送打印任务过去， cups显示：

ID  Name  User  Size  Pages  State  Control  
epson-18  smbprn.00000023 Remote Downlevel Document  admin  135k  Unknown pending since

但无法打印， 打印机转为stopped状态。
