This tool is part of the Samba suite.
smbspool is a very small print spooling program that sends a print file to an SMB printer. The command-line arguments are position-dependent for compatibility with the Common UNIX Printing System, but you can use smbspool with any printing system or from a program or script.
smbspool specifies the destination using a Uniform Resource Identifier ("URI") with a method of "smb". This string can take a number of forms:
smbspool tries to get the URI from argv. If argv contains the name of the program then it looks in the DEVICE_URI environment variable.
Programs using the exec(2) functions can pass the URI in argv, while shell scripts must set the DEVICE_URI environment variable prior to running smbspool.

The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed.
The original Samba man pages were written by Karl Auer. The man page sources were converted to YODL format (another excellent piece of Open Source software, available at ftp://ftp.icce.rug.nl/pub/unix/) and updated for the Samba 2.0 release by Jeremy Allison. The conversion to DocBook for Samba 2.2 was done by Gerald Carter
