MacOS – How to _unset_ the default printer

The PATH environment variable is simply an order list of directories over which (typically) executables are searched for and run. In short, to get you through the setup you'll need to edit /Users/<username/.bash_profile to include

export PATH=$PATH:/Android/android-sdk-mac_x86/tools

This is the most painless way to do that. Note, this assumes that you have the same SDK install path. Modify the text to suit otherwise.

1. Open up a Terminal window (don't cringe). Use Spotlight ( ⌘SPC ) and start typing "terminal". Hit return when you see it highlighted.
2. Copy and paste the following into the terminal window that opens up and hit enter.

echo 'export PATH=$PATH:/Android/android-sdk-mac_x86/tools' >> ~/.bash_profile

That's it. If you already have a .bash_profile, this will add that line to the end of the file. If you don't already have one, it will create one for you.

I know your post is old, but I was having the same issue with almost the same Ricoh Printer.

The finisher name looks like Finisher SR3020 in the OSX system preferences, but in the terminal it's a code name that you have to supply.

Type the following:

lpoptions -l

That will display all the options for your printer. One row will be titled:

Finisher/Finisher: *NotInstalled FinisherOne FinisherTwo Etc

The list of all available finishers will be displayed. My SR3020 was displayed as FinEUPHPOS. Thus I edited my script to be the following and it worked perfectly:

NAME="Printer Name"
DESCRIPTION="Printer Description"
LOCATION="Printer Location"
ADDRESS="printer.location.com"
PPD="RICOH Aficio MP 6001.gz" //printer driver file
FINISHER="FinEUPHPOS" //printer finisher name

lpadmin -p "$NAME" -D "$DESCRIPTION" -L "$LOCATION" -E -v lpd://"$ADDRESS" -P "/Library/Printers/PPDs/Contents/Resources/$PPD" -o "$FINISHER"
