Hi,
I have checked the link you provided and I believe an SRM is a kind of fiscal printer; what we call an ETR(Electronic Tax Register) here in Kenya. If so, I have developed a module for use in Odoo 8 with the POS module to print the receipts using a fiscal printer.
I developed it in C# and it is a windows service.
If this is the kind of thing you are looking for, I already have a code base and would just need to customise it for your particular device.
Best Regards,
Anthony.
