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.
where can I find the "generic PCL driver" you referred to Greg?
Also, I searched for a LJ 2100 d4river and found these. should I be working with the HP website? or an apple website? my Apple software update is current.
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
If it doesn't let you in, you will have to enable the web interface using this command in the Terminal:
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.
