Random strings printed at the end of images

Bug description

Printer prints a bunch of gobbledygook at the end of images (looks like 0s). Only happens if it printed using image and with impl=bitImageColumn. I could not get the other two (graphics and bitImageRaster) to work.

Steps to reproduce

• myprinter.image(image,impl='bitImageColumn',center=True)
• image is a BytesIO
• I use PIL to open the image (code below):

img = imgkit.from_string(current_job, False, options=kitoptions)
bytesImg = BytesIO(img)
bytesImg.seek(0)
image = Image.open(bytesImg)

Hi @robinchhetri .

According to the POS-5890 profile "bitImageColumn" is not supported.
Instead, "bitImageRaster" is the only implementation that your printer supports to print images.

Thanks @belono - I tried biImageRaster but it did not print correctly. I am currently using bitImageColumn and I don't have any issues. I manipulated the size of the image with imgkit and the 0s disappeared.
