laserwriter IIg and JetDirect 300x

[paulpsmith]

Does anyone know how to connect an Apple Laserwriter IIg and an HP JetDirect 300x? They both have rs-232 (25 pin Dsub) connectors on the back, but they don't talk to each other. Apple says to swap pins 2 & 3, RxD & TxD, but that did not help. From what I've gathered, I think the laserwriter is set up to connect to the serial port on a PC, not the parallel port. <br><br>Paul

If apple is saying to swap rx and tx connections and it is rs232 you most likely will have to look at doing some thing with the control lines . clear to send , data set ready and some other control line I cannot remember . in australia the dick smith electronics catalogue had how to wire up a Null Modem cable . If you can find somewhere how to wire up a null modem cable you will be on the right track .<br>Check out this link <A HREF="
