Samba comes equipped with a tool called <EM CLASS="emphasis"> 49smbprint</em> that can be used to spool print jobs to Windows-based printers. In order to use this, however, you need to set up the printer as a shared resource on the client machine. If you haven't already done this, you can reset this from the Printers window, reached from the Start button, as shown in <A CLASS="xref" HREF="ch07_02.html#ch07-32814"> 50Figure 7.7</a>. </p><H4 CLASS="figure"> 51<A CLASS="title" NAME="ch07-32814"> 52Figure 7.7: The Printers window</a></h4><IMG CLASS="graphic" SRC="figs/sam.0707.gif" ALT="Figure 7.7"><P CLASS="para"> 53Select a printer that's locally connected (for example, ours is the Canon printer), press the right mouse button to bring up a menu, and select Sharing.
