CognitiveTPG A798 Logo Loading

I needed to load some logos for a demo.  Other POS printers I have used have had helpful utilities for uploading logo images to the printer.  Not it seems the A798....  I only cracked it after reading and re-reading the Programmer's Guide and an extraordinary piece of luck...

From the CognitiveTPG Downloads Page you can obtain a Printer Configuration Utility for POS printers.  Download and install this (as well as the appropriate driver).  Unfortunately there doesn't appear to be any manual for this utility (I asked their tech support but was referred to the Programmer's Guide.  UPDATE 16/04/2012: tech support have now sent me a PPT hmUtility guide and some additional instructions on logo upload - very similar to what is described below), so there's a lot of scratching around in the dark....

Run hmUtility.  I have a USB connected printer.  The utility Port Selection reads "USB, PRINTER CLASS, ON".  If it says "USB, PRINTER CLASS, OFF" double click on it.

Prepare a BMP logo file.  Note this must be a 2 colour monochrome BMP.  You could use GIMP (Image->Mode->Indexed->Use black and white palette) to do this.  If you  use a RGB or Grayscale BMP it won't work.

If you want to upload more than 1 logo, select the current logo number.  Go to "Configure" and type "1D 23 XX" (XX is the desired logo number) into the Command Selection Cmd box and then press "send".

Then go to "DLoad BMP" and double click on the .bmp you wish to upload.  After a short while you should see soemthing like "Port1 download is complete".

Test print the logo by going back to "Configure" and typing "1C 70 XX 00" (XX is the logo number) into the Command Selection Cmd box and then press "send".

I think loading by script is also possible - take a look at SampleConfigurationScript.txt ([BMP] command) in the hmUtility installation directory.
