The more I find out the less I know
I have got my Posiflex 6800 Serial thermal printer running now, using the scraps of information that I can understand from the manufacturer, Ladyada, Sparkfun, and some ESC/POS info from Epsom, and a few postings on our forum. ( thanks )
I have learnt a hell of a lot, but realise theres a long way to go, and I dont have any spare time at all to learn.
So, now I can print the important text - bigger/smaller/inverted/ justified etc. - but now I need some help to get a logo ( 15k .cpp file ) that I generated as per the instructions on the ladyada mini thermal tutorial , into the eeprom of the printer - unless I make it much smaller and try to save it in the 328 eeprom?
When I tried to run the ladyada sample, ( I had made a seperate tab , and saved the file there as suggested , but when I try to run my sketch, it says progmem has not been defined , so I tried including #include <avr/pgmspace.h> but still no luck.
I have a feeling I am trying all sorts of bits from different libraries, that are not working.
Can anyone give me a clue ? I can’t seem to find how much memory the printer has now for NVM users memory, I can delete the barcode bitmaps there - I dont need them now.
