Hello friends please help me , i have been suffering with this since 2 weeks .

I have made a POS application for a restaurant . with Win-form ,c# ,.Net .
The printer Epson TM-U220 is printing the junk characters with my app.
However when i tried to print a normal text through notepad on Epson TM-U220 , it was junk too.

Now the magic is The restaurant owner has an old POS application for bill printing with that only this Epson TM-U220 prints correctly .

One more thing my app prints fine with other Inkjet & Laser printers

I am really frustrated & confused i have reinstalled the drivers for printer but still the same situation ..Can anyone please help me .

Hear is my code for printing

Here's a link to the manual for an Epson TM-U220:

http://www.icscale.com/TECH%20MANUALS/TMU220_TRG_RevD.pdf[^]

Per the manual, there is a dip switch on the Epson which determines how the printer is controlled. In one position, it is controlled via one of two types of windows drivers that you install. In the other it is controlled via direct command in the "ESC/POS" propietary command language that "doesn't require a driver".

Without digging into it further, I'd bet the "ESC/POS" language is simple ASCII characters over an RS232 port or something similar. If your printer is set in that mode, it will probably interpret every byte it is sent as a character to print -- thus the giberish you see.

Check out what port the printer is installed on and try typing something like this in the cmd shell:

echo "hello" > lpt1

And see if that doesn't print "hello" on your printer.

If you still need to support the old POS application, then you'll need to change your print function to just write characters to the printer port.

If you don't need to support the old POS application, then try flipping the dip switch and see if it fixes your problem.
