anyone working on it...
Google knows. Here is one:
"H-P C6602 inkjet cartridge,"
"5 to 6 μs pulses of 18 volts through a ULN2803 Darlington array driver chip"
5 to 6 microseconds is 80 to 96 instruction cycles so that should be fairly easy.
I want to use HP45 CATRIDGE
for better RESOLUTION.....
CAN YOU PLEASE HELP ME TO MAKE THIS PROJECT MORE EASIER...
