The title of this article is ‘Setup CUPS (Common UNIX Printing System) Server and Client in Debian’. From the title, this probably means that the shared printer is physically somehow connected to the server machine and the local or remote client is a separate machine.
This is certainly the case used in the primary developer of CUPS’s, Michael R. Sweet’s, ‘Using Network Printers found at http://www.cups.org/documentation.php/network.html

In that case, you may wish to go through the less than a dozen steps at the Linux Foundations’s ‘OpenPrinting CUPS Quick Start’ quide found out http://www.linux-foundation.org/en/OpenPrinting/Database/CUPSDocumentation

The cups.general newsgroup at http://www.cups.org/newsgroups.php?gcups.general+T may be worthwhile perusing as well

A more complete way of answering this one-printer-to-one-machine question before and after installation is probably to take Kurt Pfeifle’s adamant advice of
Read the CUPS documentation!
-and-
Read the Manual Pages!
as described in the actual CUPS ‘Troubleshooting-CUPS-and-Asking-for-Help HOWTO’ found at http://www.cups.org/cups-help.html

A possibly better way to answer these questions all at once is to visit each of these packages’ descriptions for your specific Debian version
cupsys
cupsys-driver-gutenprint
foomatic-db-gutenprint
foomatic-filters
fontconfig
libtiff4
libfreetype6
To find this info,
for Etch go to http://packages.debian.org/stable/allpackages
for Lenny go to http://packages.debian.org/testing/allpackages
for Sid go to http://packages.debian.org/unstable/allpackages

You are referring to RFC 1918 ‘Address Allocation for Private Internets’ found at http://www.ietf.org/rfc/rfc1918.txt
The 172.20.22.74 server and the 172.20.22.150 admin workstation are both within the 172.20.22.0 segment, indicating that this is probably a good thing for a group of host devices in close proximity to one another (e.g., one department’s networked PC’s on a floor.) There then could be as many other internal network segments as needed within the greater private 172.20.0.0 network (e.g., maybe on other floors or sections)

Install CUPS printer server in Debian

1. Does one need one machine for a CUPS printer server in Debian and another for a printer client? What if one wants to set up CUPS for Debian on a single machine, or else on machines where each computer has its own dedicated printer ???

#apt-get install cupsys cupsys-driver-gutenprint foomatic-db-gutenprint foomatic-filters fontconfig libtiff4 libfreetype6

Does one need to install ALL of these to get CUPS working?
Which of these (if any of these) can one leave out?
Briefly, what do each of these packages actually do?

NOTE:- If your network use DHCP it’s a good idea to set up your server to use static IP. I will use as 172.20.22.74 for the server and 172.20.22.150 for administration workstation.

What exactly do these static IP addresses represent??
Aren’t these actually translated (NAT/masqueraded) non-routable individual IP addresses within the particular 172.20.22.00 class B network used (default mask 255.255.0.0) ?
Isn’t the more common case for a private network using DHCP IP-assignment, a default class C network range in the 192.168.0.0/24 series (mask=255.255.255.0) ???
