linux下的打印机不能被共享：/usr/lib/cups/backend/smb failed

Brume

以前都是好的,系统也没有升级，但突然不能共享打印了。
本地能打印。
在win下能添加打印机，但是不能打印。
另外的linux机器通过samba现在也不能打印了，提示为
/usr/lib/cups/backend/smb failed
头都搞大了，请各位老大指教，谢谢！

cups的设置是按这里的：
4.3. CUPS Configuration

Windows printer drivers format their output for the printer before sending it across the network. You must configure CUPS to accept the pre-formatted output by uncommenting the following line from /etc/cups/mime.convs:

application/octet-stream   application/vnd.cups-raw   0   -

Also uncomment the following line from /etc/cups/mime.types:

application/octet-stream

Now CUPS must be told to allow connections from other machines on the network. Add these lines to /etc/cups/cupsd.conf:

<Location /printers>
AuthType None
Order Deny,Allow
Deny From None
Allow From All
</Location>

As in the Samba configuration, this configuration allows any computer to connect to your printers and is not recommended for computers on untrusted networks. For information about tightening access control to your printers, see the cupsd.conf man page and the CUPS documentation.

Finally, restart cups with the following command:

/etc/init.d/cupsys restart

Your Linux printers should now be shared to Windows PCs on the LAN. Follow the usual steps for adding a network printer to your Windows PCs, and remember to print a test page.

在windows下提示的是：
无法创建打印作业

搞定了，原来是权限的问题，将/home/smbprint的权限设成777就行了，唉！
