We had a similar situation with Zebra printers - the output routing was really specific to the user ID and we didn't want to change output access control and manage it on the SAP side. At the same time we couldn't just use LOCL device with Zebra printers because they needed a specific driver.
Our workaround (you'll need help from a Basis admin or someone who has a clue about printer administration to set this up) - create new printer in SPAD called 'Local Zebra'. It has the device type of regular Zebra printer (e.g. LZEB2) but Access Method = F (Printing on front-end), like LOCL. And in the 'Host printer' we put 'Zebra'. Then on the users PCs we configured the printer called 'Zebra' (these names are custom). So this basically combines Zebra SAP driver with the convenience of using LOCL front-end printer.
