The desktop: Linux Mint KDE, hooked to a HP 1210 and printing beautifully. The desktop is hooked to a wireless router that is hooked to my DSL modem.
The laptop: Linux Mint XFCE, which accesses the network through the aforesaid wireless router.
The question: Why can't I find the printer attached to the desktop, and use it from my laptop?
I've networked printers in Linux many times, and for many different distros. I put in the printer's IPP as follows:
psc_1200 is the name that KDE gives for this printer. 192.168.1.102 is the computer's IP address according to my router. But, I've also tried with the hostname of the desktop computer:
Neither works. What else should I try? How should I configure either KDE or XFCE so that the laptop can see the printer?
