Windows 7 - Hp printer 2100 laserjet... Issues printing/possible driver?

HP Laserjet 2100 got on craigslist for $15... may be the problem right there but i know these are workhorses and just need to see if its the printer, the machine, driver, or the operator's error (entirely possible)

hooked it up to usb and yes alls well, things print but i switched a few things in the printer settings such as the dpi i switched to 1200 as well as the printer paper feed location, thats about it. now doesnt print at all.

also was looking to maybe get this tunedup... any suggestions? all printer shops say its better just to buy a new printer. i agree, but in the long run the 2100 should last a loooong time... like a honda.

or quite possibly may use as a trade in for a new printer. but i am not sure whats a better option. i'd like it to go wireless but would need a print server i think. my old router i thought could work as print server but linksys/cisco people said NO. its a wireless N lonksys 120n router... then also i'd need a parallel port to ethernet cable... *sigh* maybe just easier to get new printer...

any suggestions to my ramblings would be sweet

thanks

hp has in my opinion one of the most confusing deals on the planet regarding this printer... i think i installed the universal driver for this printer and all is well... when i hit "print" it takes forever to activate the printer and get things rolling... and thats when it was in 600 dpi mode... who knows about anything else... may be printer, driver, or settings... whatever... i guess i should check with an HP forum.

i appreciate your linkage, but was looking more for HELP-o... sorry i am not a linguist in windows, although i did see that little link for updates to drivers there in the mid to upper right so i'll have to check that out when i get home...

regards
