OK its the later who got your problem.

Here we go with ALL the code required for printing :
P1.3 is the Strobe pin, P1.4 is the Busy pin and the processor an 8052 @12Mhz. This is a memory mapped setup - modify based on your setup.

Call PRNOUT with ACC loaded with the character ( ASCII please ) to be printed. Thats all.

PRNOUT: MOV P2,#ADDR_HI ; Send 1 character to printer
MOV R0,#PRN
MOVX @R0,A
CLR P1.3 ; Strobe pulse start...
MOV R4,#50
PRN_DLY:DJNZ R4,PRN_DLY
SETB P1.3 ; Strobe pulse end..
WAIT: JB P1.4,WAIT ; Printer Busy. Wait.
RET

Disclaimer : This is the basic code. This cannot handle Printer error states , paper out and stuff like that. OK the road has been shown - now you walk.
