Hi all...

Thank's in advance

If you only have a number of graphics to print, then storing them in memory already in the correct format for the printer is the easiest. I have found that writing a simple program to convert a 2 colour BMP file to work quite well. If you need to dynamically generate the graphics, then if you have enought memory for a complete "page", then generate the image first in a block of memory. You can either make your plotting routine to this block generate the graphics data directly in a suitable format for the printer, or in a easier X,Y orientation, and the convert a 8 or 9 pixel row at a time to the ESC/P2 format when you write to the printer. If you do not have enough memory for a whole page, then you will have to do it in blocks. If you need to go this far, then I recommend you look at the opensource GIMP printer driver project at sourceforge.

I need to dynamically generate the graphics; i think to make a monocrome bitmap with the graphic that i need to print. In my system i have no memory problems. My problem is found detailed information to send data in the correct format for the printer (EPSON LQ300+); i think to use ESP/P2 commands, but i have no experience with them.
Thank's in advance
