M84Pro Service Manual PN: 9001113A Page 3-1 3 INTERFACE SPECIFICATIONS This section presents the inte rface specifications and include det ailed information on how to properly interface the printer with the host system.
Section 3: In terface Specific ations M84Pro Service Manual PN 9001113A Page 3-2 M ULTIPLE J OB B UFF ER The printer is able to continuou sly receive print j obs while compiling and printin g other jobs at the same time. It act s much like a “print buf fer” to ma ximize the performance of the host and the printer .
Section 3: In terface Spe cifications M84Pro Service Manual PN: 9001113A Page 3-3 IEEE1284 PARALLEL INTERFACE The parallel interfa ce for the M-84PRO printers is a Plug-In Interface Mod ule that can be inst alled by the user . It conforms to the IEEE1284 sp ecification.
Section 3: In terface Specific ations M84Pro Service Manual PN 9001113A Page 3-4 RS232 SERIAL INTERFACE The High S peed Serial Interface is a Plug-In Interf ace Module that can be inst alled in the printer by the user .
Section 3: In terface Spe cifications M84Pro Service Manual PN: 9001113A Page 3-5 R EADY /B USY F LOW C ONTROL Ready/Busy is the hardware flow control method for the serial interface on the M-84PRO printers. By raising/lowering the volt age level on Pin 20 of the RS232 C port, the printer notifies the host when it is ready to re ceive data.
Section 3: In terface Specific ations M84Pro Service Manual PN 9001113A Page 3-6 D ATA S TREAMS The data streams for X-On/X-Off and Ready/Busy flow co ntrol are constructed in the same way as they are for Ready/Busy flow control (<ESC>A . . Job#1 .
Section 3: In terface Spe cifications M84Pro Service Manual PN: 9001113A Page 3-7 Optional Interface, pin 6 (DTR) and pin 5 (CTS) must be held high by the host.
