I finally solved my printer problem!
I bring home an apple laptop and plug the printer
with it in appletalk and run Apple Printer utility
software to see the config of this f... printer.
Now let's see. The auto-test page on power-up was
disabled (paper economy I suppose). Since the beginning of my adventure, I've never been able to see the config of the printer that is written on this page.
I've enabled this feature and on power-up it printed me an auto-test page that includes all the port settings, number of copies done,etc.
Surprise! the printer was configured, with the DIP switchs on the right positions before power-up, to RS-232 at a baud rate of "57600".
WOW, what a BOMB!
I've bought this printer used and probably the guy
before me sends a postscript that configure the baud rate at other speed than the 9600 standard.
I knew it was possible to do that and I wanted to do it after I was able to make it works at the 9600 standard. I have the little postscript to make the change.
But what I didn't know is when you use the procedure from apple to reset the printer, the baud rate didn't reset to standard 9600. I've made the reset procedure many times during my troubleshooting sessions and it made no difference at all.
That was my problem! and I
didn't think to change my baud rate on the windows
port to 57600!
That's only what I've done and suddenly my f... printer became my new default printer! It works.
Finally, I wanna thank you for all the help you provide to me and be sure you'll stay in my bookmark list!
P.S. did you received my comment letter that I've sent via your comment page? It returns me a strange page when I clicked the submit button.
