We use both of these types of printers for our Rx. We always use the installed driver for the printer....never more do we try to use our own initialization strings, etc. We used to do this and it means that you end up boxing yourself into a corner when a new model comes out, etc. We do this on these very printers as we speak...no issues...past the standard stuff
I have use the Dymo printers for my VFP application for a long time, so I believe I would not have a problem dealing with the Dymo printers even the dual head ones.
I am more worry about the receipt printers, do you use the Windows Generic Driver or the printer's driver? In my case I am dealing with 2 types of receipt printers the Epson and the Star. I was hopping to find a library that would take care of sending the correct Esc commands.
Can anybody recommend a VB.NET library to print receipts in those POS receipt printers?
