Normally, you can use a script to set CUPS printing options for each printer. These options are set at printer installation:

#!/bin/sh
# install printer
lpadmin -p "Xrx_6700_Techlab" \
-D "Xerox-6700-Techlab" \
-L "Tech Center" \
-E \
-v "smb://it/Xerox-6700-Techlab" \
-P "/Library/Printers/PPDs/Contents/Resources/Xerox Phaser 6700DN.gz" \
-o printer-is-shared=false \
-o Duplex=None \
-o auth-info-required=username,password \
-o InputSlot=Tray2

 

 

Each -o command will edit an option available on the printer. Available options can be displayed using the lpoptions utility: 

# check printer options
lpoptions -p Xrx_6700_Techlab -l

 

Unfortunately, for some printers, setting CUPS options does not apply to the GUI print window. In case of the Xerox 6700, setting the Tray2 option in CUPS does not apply it in the GUI. We can use a script that will modify the available printer presets for the user as a workaround.

---

Use an installer pkg that will deploy a pre-configured plist with the presets. The pkg should include a postinstall script to modify the plist for the user.

Printer GUI Presets can be created on any system and then copied out - the plist resides in ~/Library/Preferences/ com.apple.print.custompresets.forprinter.QUEUE_NAME.plist

After the installer pkg copies this file onto the new user's home, a script will be needed to change its settings to reflect the new user and the new system:

#!/bin/bash

# define username
USERNAME=$(logname)

# define variables
XR6700PLIST="/Users/${USERNAME}/Library/Preferences/com.apple.print.custompresets.forprinter.Xrx_6700_Techlab.plist"

When the installer completes, the user should see the following presets for the Xerox 6700 printer. The default will be the tray 2 plain paper setting:
