Mac Printing Scripts

Hi all. I’m doing something a little different this time and I’ve got 4 small scripts relating to printers on Mac that I’d like to share. They’ve been pulled together from various places and tweaked many times since I’ve started using them and I thought I should share what I’ve got. Hopefully they’ll help save another Mac Admin some time!
Add Everyone to Printer Admins
This script uses the ‘dseditgroup’ command to add the “Everyone” user group (which all users are a member of, hence the name) to the “lpadmin” group (effectively the ‘printer admins’ group).
This change will allow all users to carry out tasks such as resuming a print queue without entering administration credentials. As long as the users are not administrative users themselves, they won’t be able to add or remove printers from the Printing System Preference pane.
I’ve used this for staff Macs in schools where the staff members would take a device home, and attempt to print to the school print server queues. Once the print job timed out, the queue would be paused and require an administrative credentials to resume.

dseditgroup -o edit -a "everyone" -t group lpadmin
exit $?

Disable Printer Sharing On All Queues
This script uses the lpstat and lpadmin commands to disable printer sharing on all print queues. Often, when a print queue is deployed using management, it is automatically configured as shared. Now, without enabling printer sharing in the Sharing Printing System Preference pane this won’t do much, but can annoy / worry some business owners.
I’ve used this script in a handful of places where users may add print queues themselves, or the site uses a particular method to deploy print queues that typically have sharing enabled but not desired. This script can be run each time a print queue is added (afterwards!) or every day / week / month etc.

lpstat -p | grep printer | cut -d" " -f2 | xargs -I {} lpadmin -p {} -o printer-is-shared=False
exit $?

Remove MCX Printers
This script will use the lpstat and lpadmin commands to find any print queues listed as ‘mcx’ print queues, and remove them.
I’ve used this script when migrating a few customers from one management solution to another. It pruned out the previous management solution’s print queues, ready to receive the new management solution’s queues. This ensured that the devices in question were in a ‘known’ state, rather than possibly be missing queues or have duplicate queues

for printer in `lpstat -p | grep 'mcx ' | awk '{print $2}'` ; do
        lpadmin -x $printer
exit 0

Remove All Print Queues
This script uses lpstate and lprm commands to loop through and remove all locally added printers.
I’ve used this script in a similar way to the Remove MCX Printers script above to reset a Mac device to a ‘known’ state regarding the print queues, i.e. no print queues!

lpstat -p | awk '{print $2}' | while read printer
  echo "Clearing Queue for Printer:" $printer
  lprm - -P $printer

There you go! I hope that they can prove helpful to someone. Apologies that I cannot remember sources for the information and / or scripts. Please feel free to give me a shout out and I’ll edit the post to give credit where credit is due!
