Copying Printer Config from one Apple Mac To Another

KB Home   |   Copying Printer Config from one Apple Mac To Another

The printer configuration information on Mac OS X is stored in the directory:

/etc/cups

This is a “hidden” system directory storing the CUPS configuration. Recursively copying this directory from one system to another will duplicate the printer configuration. Mac OS X administrators may find the following shell script example useful. It uses a secure shell (ssh) to pull and duplicate the printer configuration from a master/source system. This script will work with most printers that use standard PPD based drivers, but may have problems with some drivers that use custom components (e.g. Epson wide-format printers).

How to use:

1) Copy script (contents below) into a file called pull-printer-config.sh on a target system (the system that needs the printer config). Verify that Remote Login is enabled on the Mac that currently has the printer configured for the admin user you’ll be logging in as. You can enable Remote Login in System Preferences > Sharing > Remote Login.
2) Make sure the Printer Setup Utility is closed.
3) Open a command-prompt and cd to this directory.
4) Run the script:
           sudo sh pull-printer-config.sh <sourcemachine> <adminuser>
where:
<sourcemachine> is the name or IP of the system who’s printer config you’d like to copy.
<adminuser> is the name of an “admin” level account on the source system. You will need to know the password associated with this account.
Tip: Advanced administrators may choose to take advantage of SSL host keys and a custom /etc/sudoers file to avoid the need to enter a password.

The script:

Copy the contents below into a plain text file called pull-printer-config.sh
