The opposite CUPS hacks during this bankruptcy have fascinated about its correct web-based administrative interface and the way the interface simplifies and standardizes printer setup, whatever the form of CUPS customer you are configuring. besides the fact that, like such a lot Unix/Linux courses, you may also administer the CUPS server by way of at once manipulating its configuration dossier, /etc/cups/cupsd. conf. whereas this can appear a little intimidating at the start blush, the layout of this dossier is de facto very simple and is conceptually evocative of an Apache configuration dossier (which we now have all most likely needed to adjust at one time or another). a number of uncomplicated adjustments to this dossier can fast upload a brand new layer of defense on your CUPS printing atmosphere. Many sysadmins are paranoid at the present time, and for reliable cause.
