Delayed::Job.enqueue QrCodeGenerator.new(client,request,params[:batch_quantity].to_i)

1. If this job is always gonna be the same job but just with different input parameters, you can just run QUEUE=myqueue rake jobs:work because that rake process will run one job at a time. You can then run another simultaneous delayed_job rake process to run other queues as a concurrent worker (if you have other jobs that needs to be processed).

2. If the sequential jobs you are talking about however are of different jobs / class, then you can just call the other job once the first job has finished.
