Deskjet 1000 hp- commands

I have installed an HP Deskjet 1000 j110 on my Slackware system (13.37).
I am trying to print more than 1 page out of 2 or more. No luck so far. Found that there are about 30 odd commands like hp-linefeedcal, -print, -pkservice, -printsettings, -devicesettings, -systray, -check, -align, and -firmware that might be useful but can not find any explanations for the commands. Does anyone have definitions for these and others or know of a document other than HP's release notes which covers them? I need more than what is available with the -h option.
These are the ones obtained by typing hp- at the terminal and hitting TAB 2x.
