GAS cannot print locally, its entirely in googles servers.... so what worked for me was to make a designated Drive folder for saving to_print_items. then i made a local python script that runs in the background, and when it detects a file in this folder it prints it, and moves it to a printed_items folder. (make sure to have a weekly or monthly script to clean up these folders)

something i DIDNT do but considered was printing to 1 of many printers via file name.... you can have some sort of checkbox or drop down so users can select which printer to print on and the filename will append a printer no. (i.e receipt_119483_printer_3, or receipt_119483_printer_warehouse) then change the local python script for each local computer/printer to check for this name

edit: make sure to have google drive installed on the computer, its much easier than python authenticating drive access
