So my wife won a laptop (ASUS X551M), an HP Deskjet 1510 printer and an office desk today in a raffle. Currently I am updating Win 8.1 to Win 10 (free upgrade), but the printer was the real nut. Drivers are for 10.6 minimum. But, a little Googling reveals that you can use the drivers for the Officejet Pro 8600 (an All in One, just like the 1510) which DO install on 10.5. Now, I have an ASUS-AC66U router (courtesy of Sprint) which has USB ports. So, I hooked the DJ up to the network through the USB ports on the router. Added the printer several times using LPD and got nothing. But, I thought, what the hell and added it as an HP device and guess what? It printed! So, I've got a networked 10.6 only HP printer now that can be printed to from any computer on my network. Minimum 10.6 Snow Leopard my ass!
