Image Printing not working correctly

[GoogleCodeExporter]

When trying to print an Image, Barcode or QR-Code, the Printer only prints a 
lot of Characters.

Printer Model: Epson TM-T88III

I'm on a Raspberry Pi - Model B
OS: Debian GNU/Linux 7.0 (wheezy) (Raspbian “wheezy”)

Python:
- Python 2.7.3
- Python Imaging 1.1.7

I too am having this problem, with an Epson TM-T20. Is there any further 
information? Does something need to be reconfigured on the printer?

I too am having this problem, with an Epson TM-T20.
Only random characters are printed when I try to print an image or a QRcode.
Can someone please point me to a website which gives examples of python scripts 
for using python-escpos?

I have verified that I meed the prerequisites.

The problem seems to be related to printing text before the image.

This works (albeit with some banding in the image):
from escpos import *
Epson = printer.Usb(0x04b8, 0x0202)
Epson.image("logo.gif")
Epson.cut()

This prints "Hello World" followed by a lot of characters (not the image):
from escpos import *
Epson = printer.Usb(0x04b8, 0x0202)
Epson.text("Hello World")
Epson.image("logo.gif")
Epson.cut()

It looks like the catch, at least in my case, is to make sure to put a newline 
between the text and the image:

Epson.text("Hello World\n")
Epson.image("logo.gif")

Does print the text, followed by the image, as expected.

Wow! Thanks for that hint :-) It's exactly as you said: It works perfectly with 
"\n"!

cheers!

Yes!!

Epson.text("Some text\n") or just insert an
Epson.text("\n")

after printing a text,
and image, qr and barcode printing started work on my TM-H6000 serial printer.

Thanks a lot for the hint.

This issue has been solved by murray.melvin.

The wiki entry has been updated accordingly to reflect the newline character 
'\n' at the end of the text.

Thank you very much murray.melvin for your contribution to the project.
