Android Question Image Printing

[edgar_ortiz]

Hi,

I already print "text" to a Bluetooth printer.

I'm trying to print a image file (png)... but I don't understand.

Any help is welcome.

Thanks in advance

It looks like the image must be in BMP Format...

There are several Threads about this:

I guess you have to convert your graphic to a Bitmap and process every byte of the graphic.
Unfortunately i found no solution how to do this in B4A. Here is a Delphi example, maybe it helps.

hi
I think the BT printer should support graphics!. I have used Zebra BT printer and could print Images.
It has got (zebra printer) it's own printing command. http://www.ptshome.com/kb/Manuals/ZPL_Vol2.pdf
