Printing with dot matrix and thermal printers

Anyone able to print standard and POS invoices with a Dot Matrix and Thermal Printer? I can’t seem to get mine to work - the printing quality is very low.

Please assist.

For thermal Printers see - https://github.com/frappe/erpnext/issues/2808

It would be a good idea to include this in the app. Will be great if you can send a pull-request.
