Re: [parisc-linux] Printing problem with HP9000 712/80

Hello,

Thanks all of you for the answers. Now at least I know that the unaligned
access message is normal and the harmony is full duplex.

About the printer.

This is a full-blown (not windows only) printer. I tried to connect
it to another Linux box, and I could print a pcl file by catting it to
/dev/lp0. I could also print a text file (/etc/passwd and an ^L at the
end) by sending it to /dev/lp0.

However, when I connect it to the HP9000 712/80 box, then nothing happens
even if I tried to cat the same pcl file to the printer port. I massaged
the connectors to make sure that there is no contact error. This is not
the case since the printer works perfectly on the two other boxes. On
the other hand, I do have an old Panasonic dot matrix printer, and if I
connect that printer to the box, and send a text file with an ^L at the
end, it does print. So now I am in the situation that the HP computer
doesn't talk to the HP printer but to the Panasonic one.

The printer has only one connector which seems proprietary, but the
other end of the end of the cable is parallel.

Thanks, Vilmos
