Problem using StringIO file object

[Joshua Burvill]

Hello,

I have the following script for printing something to a print server using
ftplib, but it seems that I have a problem with putting the content into the
file object as is shown by the following output from the script.

Any tips?

    ## Create file-handle to a "file-like" string
    file_handle=cStringIO.StringIO()

    val=ftp.storlines("STOR " + portname, file_handle)
