Epson tm u200b bitmap

Question

I'm working with a Epson Tm U200B dot matrix printer (receipt printer). I got a template of the receipt in excel (some text and 2 images). It prints ok from excel, but now I'm doing and .net app to print from there.

The printer works on an COM serial port.

What:

• Print a logo and some text in te same line: "[LOGO] THANK YOU"

What have I tried:

• On windows I tried the Printer object that comes with .NET (such as e.Drawing.DrawString, etc). The printer is ultra slow using this and it won't use the correct font.

• Installed POS net

  • Microsoft Point Of Sale (PoS.net) Download
  • MS Support Article
  • Epson OPOS Drivers
  • After all this, the TM U200B is not supported. :(

I took source code from many websites, forums, and here but nothing.

• This question and this
• The Nicholas Piasecki's article
• I've read about ESC/POS command but no luck. I can't get my printer to print a BMP logo.
• Couldn't find any "ESC * m nL nH d1...dk" sample to work with.

I'm hopeless and exhaust, trying almost anything I found on the internet... If someone have some experience with this, please help me.

Answer 1

So, short answer:

I bought a Tm U220A which supports ESC/POS. Use PrintBitmap() function (OPOS.net) and reverse feed 2 lines, and print the text.

I know it's not the perfect workaround, but it works like a charm.

Answer 2

I feel your pain I spent all of last weekend working out receipt printing from a webbrowser.

As I mention in the above answer download jZebra library, it has a sample.html page and I recall seeing a Print Picture function.
