CUPS users may get the exact same package from https://www.cups.org/software.html. It is a separate package from the CUPS-based software files, tagged as CUPS 1.1.x Windows NT/200x/XP Printer Driver for Samba (tar.gz, 192k). The filename to download is cups-samba-1.1.x.tar.gz. Upon untar and unzipping, it will reveal these files:

root# 

tar xvzf cups-samba-1.1.19.tar.gz

cups-samba.install
cups-samba.license
cups-samba.readme
cups-samba.remove
cups-samba.ss

These have been packaged with the ESP meta-packager software EPM. The *.install and *.remove files are simple shell scripts, which untar the *.ss (the *.ss is nothing else but a tar archive, which can be untarred by “tar” too). Then it puts the content into /usr/share/cups/drivers/. This content includes three files:

root# 

tar tv cups-samba.ss

cupsdrvr.dll
cupsui.dll
cups.hlp  

The cups-samba.install shell scripts are easy to handle:

root# 

./cups-samba.install

Installation is complete.       

The script should automatically put the driver files into the /usr/share/cups/drivers/ directory:

root# 

cp /usr/share/drivers/cups.hlp /usr/share/cups/drivers/
