A few older HP printers might have trouble printing because of a bad HP driver. This behavior is easily remedied by doing the following:

1. In your Windows directory, you will find a file with a name similar to HPFDJC05.INI. This is the initialization file of the HP driver. This file needs to be repaired.

2. Reinstall the Printer drivers for the printer. We suggest that you download the latest version of the driver for your printer from the HP web site. (This will update the INI file, so you will be able to recognize it by date in Windows Explorer.)

3. Start up NCSS and go to the spreadsheet. While looking at the NCSS spreadsheet, choose Edit and then Options.

4. Choose the Constants tab.

5. Type the name of your INI file in the HP 820 Printer File Name box.

6. Quit NCSS.

7. Start NCSS back up. The printer should now work.

How it works.
The printer apparently sends instructions back to the driver program to put it in debug mod. To overcome this, we make a backup copy of the driver file as NCSS starts. When NCSS quits, it replaces the existing copy of the INI file with this backup copy. Any changes that have been made are replaced.

We have reported this problem to HP.
