I recently migrated from a 2 year old MacBook Pro to MacBook Pro Retina and now cannot get my LaserJet 3200 to print. I downloaded drivers from HP Support site but printer just prints a line of gibberish per page, and many pages.

OS X Mountain Lion: Reset the printing system

If LInc's suggestion doesn't work, try resetting the printer itself.

I recently had some HP printer problems and that did the trick.

The symptom of some gibberish on hundreds of otherwise blank pages is caused by using a postscript driver for a non-postscript printer. You printer uses the HP PCL 5e page language but not postscript.

You should try the generic PCL driver or, I saw somewhere on the HP site, use an HP Laserjet 2100 (non-postscript) driver for this printer.

Sorry if I was a little bit obtuse. No need to download/install anything else.

In Print & Scan prefs, click + to add, then select "Add printer," then instead of letting it choose the driver, go down to "Use:" and select either generic PCL or HP Laserjet 2100.

Whoa - I just tried that and "Select Printer Software" and "Other" didn't offer the choices I expected.

So, I guess you need to add the printer using the built-in web interface. Use a browser and go to

localhost:631

If it doesn't let you in, you will have to enable the web interface using this command in the Terminal:

cupsctl webinterface=yes

Once you get in to the web interface to CUPS, I think it is mostly self-explanatory. Go to the Administration tab, then click Add printer.

You run commandline commands in the Terminal (in Utilities folder).

I think you should try to Add in Print & Scan preferences pane first, though.
