The command
lpadmin -p Samsung-ML-1250 -o usb-no-reattach-default=true
saves the changes forever, the changes are kept also after a reboot.
To undo the changes, you have to run
lpadmin -p Samsung-ML-1250 -R usb-no-reattach-default
The editing of the /usr/share/cups/usb/org.cups.usb-quirks file as I described in my previous comment has the same effect and it also survives reboots.
