Angry Missing lp / lp0 device ??? (Slackware 10.0)

I was installing the printer through the "Add Printer Wizard" in Printer Manager. But when I selected "parallel" for local printer and clicked Next, I got this error in a window: Empty URL

I checked my loaded modules and saw that lp wasn't loaded. I thought Slackware loaded this by default.

Then I tried to enable the module, but I got this:

root@cesar:/dev# insmod lp

What the heck???

In /etc/rc.d/rc.modules, parport and lp stuff is commented out by default. IIRC this was also the case in 9.1.
BTW, lp is dependant on parport, which is kinda what the error message is hinting at .

Thanks! That solved my problem. I don't recall doing those additional steps since I had the printer working in Slackware 9.1.

Now the only problem I'm having in Linux is that the printer prints ink a bit off the page (My Xerox printer has been doing on every Linux distro I've experienced. Oh well).
