How can I change "nobody" of a network printer to "machine name "?

How can I change "nobody" of a network printer to "machine name "? -- Linux general technology-Linux technology and application information. for details, refer to the following section. The company uses RHEL6.2 as a printer server to print windows connections. (Xp, 32-bit, and 64-bit win7 are all supported)

But encountered problems: 1. the printer with more than two Chinese characters connected to the XP system will display "unable to complete the operation", that is, it cannot be installed. Printers Named below two Chinese characters can be installed and printed normally.

2. the "owner" of the print job sent to linux by windows is nobody and the user name cannot be displayed.
(Try: the user name is successfully displayed in suse.
But failed in RHEL6.2.
The windows user name is the computer name (netbios ),
Setting samba in suse in smb. conf is ineffective. (Xinetd and cups are enabled, of course)

This involves the function for computers to automatically add users (add machine script = ...)
)
After trying for a long time, I still failed to change the "nobody" of the network printer to "machine name ".
