I will give you the entire procedure, which is guaranteed to work. However, if you have any difficulty with it, I suggest that we work on it interactively, when we are both online. Here is the procedure for uninstalling and reinstalling the printer driver software on a mac:
This is the installation procedure. Each step must be done in the order given in order for the process to work. This thorough method that I have developed, always works. First, please do the following:
Do you have other working printers installed on your computer? (If so, you may skip the next step.)
Reset Printing System - If there are no other printers installed on the mac, the printing system should be reset, in order to guaranty a clean installation. Use Apple icon in the top left corner of your screen to select System Preferences. Open the Printers & Scanners window. Hold the CTRL key down and user the select button on you mouse to click anywhere in the left side of the printer window. Then select Reset Printing System on the menu. (Skip the next step.)
Remove Print Server Icons
[If there are other working printers, instead of resetting the printing system, just remove the print server icons for the printer that is not working, and skip resetting the printing system, since it may not actually be necessary. If it becomes necessary, It may have to be done later, followed by a reinstallation of the printer we are working on an addition of the other printers to restore them.]
Uninstall Printer Software - Use Finder to open the System Preferences > Applications folder and locate the subfolder for your printer. Drag the entire folder into the Trash folder.
Restart Computer System - Use the Apple icon to restart your computer operating system. You can rejoin this conversation by selecting the link in your notification email.
Download Printer Software - Select the following link to download the Full Feature Printer Software and Driver package for your printer and operating system:
LINK FOR SPECIFIC PRINTER FROM OFFCIAL MANUFACTURER'S SUPPORT WEBSITE
Install Printer Software - If you do not see a Run button, use your Finder to locate the downloaded printer file in the Downloads Folder. Use the select button on the mouse to select the heading on the Date column and sort the download files by date, so that the required file is at the top of the list. Select the file to open it, and follow the prompts to install the software.
Print Test Page - Use Apple icon in the top left corner of your screen to select System Preferences. Open the Printers & Scanners window. Highlight the print server icon for your printer and use the menu button on your mouse to open the Print Properties menu. Select the Print Test Page button in the Printer Properties dialog box.
