I want to print the receipt to thermal printer without using OPOS driver.

Please guide me in this case.

Is it possible without driver?
prashant1111 16-Feb-11 5:43am
Yes, It is possible But I dont know How ?

you may use ESC/POS commands also. it would be easier. Some of the thermal printers connected to USB / parallel port can be printed using the .net printing method. No need drivers. I have used ESC/POS for a receipt print connected to COM and print barcode printer connected to USB using normal printing drivers available in .Net

How to use that command

YEs AlbinAble you are right. My printer is connected through Port and I want to print using that port. SO what approach I follow to achieve this. But keep in mind that no OPOS driver is installed on the system. I want to print the receipt on that printer.

You first must determine which Printer Command Language your printer supports as ESC/POS is NOT the only one!!! If you have a Zebra printer, then ZPL or EPL are needed not ESC/POS. Other brands also have their own languages. So first of all, check that and then go ahead.

Hi Create a Generic text printer in the pc (Add new Printer...or google it how to add a generic text printer)

Look at this article how to send raw data to printer.[^]

using this you can send ESC/POS commands to the printer.

For ESC/POS commands reference use this link[^]

or google it for more
