I understand you need printer drivers for OSX 10.6.8.
Don't worry I'll try to help you out.
Did you make any changes to your printer?
I have checked the records and I don't see drivers for OSX 10.6 from HP, the drivers available at HP website starts from OSX 10.8.
However, you can try installing the printer using MAC built in drivers.
When you add your printer to the printer queue on the Mac instead of using the HP software, an HP driver installs through Apple Software Update for most printers.
Turn on the printer, and then connect a USB cable to the printer and to an available port on the computer.
Click the Apple menu, and then click System Preferences.
Depending on your operating system version, click Print & Fax, Print & Scan, or Printers & Scanners.
Check if the name of your printer displays in the Printers list. Do one of the following steps, depending on if the printer is listed or not.
If your printer is listed, remove and re-add the printer to confirm communication and to make sure the correct driver is used. Click the name of your printer, then click the minus sign to delete the printer. Once the printer is removed, click the plus sign, click Add Printer or Scanner, click the name of your printer, and then continue to the next step.
If your printer is not listed, click the plus sign, click Add Printer or Scanner, click the name of your printer, and then continue to the next step.
If your printer is not listed in the Add Printer or Scanner window, make sure the printer is turned on and connected to the Mac and that you have an Internet connection, try to add the printer again, and then continue to the next step.
Click the Use or Print Using menu, and then select the name of your printer.
Selecting a Generic driver option from the Use menu can result in limited printer functionality.
Click Add to add the printer to the list.
Try to print, scan, or fax, depending on your printer functionality.

Let me know if this helps!
Have a pleasant day ahead! 🙂
