I guess I periodically need to do a CUPS rant. So here it is.<br> system-config-printer does not really configure CUPS printers. If you<br> don't beleve me try to change the configuration of a printer using<br> system-config-printer by using the CUPS web interface (localhost:631)
<br> or by using the actual CUPS configuration commands which are<br> principally lpadmin and lpoptions. It can't be done.<br><br> system-config-printer fakes CUPS printing , I suspect, through the<br> secret program running in the background called printconf-backend.
<br> And if you insist on using lpd protocol rather than the CUPS ipp<br> protocol you are aided by the cups-lpd daemon.<br><br> system-config-printer works most of the time but when you get into shared<br> printers or print servers you quickly get yourself in trouble.
<br> Configuring clients for a print-server under real CUPS is trivial. You do<br> nothing except put a line in the client.conf file on the client<br> telling it which print server you want to use.<br><br> People seem to be complaining more and more on printing failing on
<br> their FC4 machines and if the printers were configured using<br> system-config-printer that may well happen.<br><br>CUPS has been the printing system in fedora for a while and in FC4 it<br>works as it should and therefore it should be used.
<br><br>The best way to start is to configure printers using the CUPS web<br>interface and set the default printer using lpoptions although it<br>probably can also be done in the web interface.<br><br>All the documentation is available through the web interface so
<br>finding out how it works should not be a problem.<br><br>That is my rant and I am sticking by it.<br><br><br>[snip]<br>-------------------------------------------<br>Aaron Konstam<br>Computer Science<br>Trinity University

Of course you searched the list archives and found where several CUPS
posters were directed to the CUPS article "Why am I no longer able to
control my printing system?". Article #301 was on the front page of
their web site until recently. The aritcle recommends turning off the
cups-config-daemon program, "which overwrites changes to the
/etc/cups/cpusd.conf file with whatever defaults they have assigned for
your security configuration."<br>
