hi to all i am trying to interface Parallel Printer. i used only STROBE and BUSY command line and all data line for interface to EPSON LX-300 and EPSON LX-300+II. the when i connect EPSON LX-300 it works fine and print each and every thing which i feed to it through microcontroller(P89V51RD2BN) but not working properly for EPSON LX-300+II. i.e. with EPSON LX-300 Printer output is KEIL FOR 8051 with EPSON LX-300+II Printer output is K IL OR 8 51 or it omit some different alphabit
can tell me why this happenning.
the printer port of computer can be used for data in or out, look on this topic for further information, how we can use parallel port for interface with PC. microcontroller51.blogspot.com/.../parallel-port-of-pc.html
