Cheapest POS ETR solution (ESD/Fiscal printer)

Looking for ETR solution suggestions.
Most are selling about 60k >> too expensive for startup business.
-I have thermal printer do I need ESD only or fiscal printer (pros/cons?)
-Also printer should use the very tiniest size of receipt, like <2 inch. (Which models exist?)
*Running Dynamics RMS
*Already have handheld ETR

ETR is 25k

ESD’s and Fiscal Printers are the ones retailing at 60K plus. I think it’s important to understand the setups.
ESD usually work hand in hand with a thermal printer while Fiscal printer is usually a stand-alone. Both are integrated into the system(In your case RMS).
ESD are more advantageous as they are known to be more stable. Most companies, say for a few supermarkets, are using it.
Also in case you want to add a new selling point you’ll only need to add a thermal printer (retailing at 16-25k depending on the quality). This is compared to Fiscal Printers where you’ll have to chuck out 60k plus each time you want to add a new one.
You can also go for an ETR (25k, portable can be carried around) but know that this operates independently from your Point of sale system. That is to say you’ll have to generate receipts manually each time you sale. Forgetting to do so may get you in trouble with the tax-man.
