Hi

I recently got myself a sparcstation 5 and now I'm planing to turn it into a printing server. It has two ports on the back that say "Serial A" and "Serial B". Are these normal parallel-ports that I can put my printer in and what /dev/-names do they get in openbsd? bpp0 and bpp1? I've tried to dump some raw text to those devices but my HP Laserjet 1100 doesn't respond in any way. bpp0 is listed in dmesg like this:
bpp0 at sbus0 slot 5 offset 0xc800000: DMA2

No.

You answered your own question there... They are serial ports.

So it's not possible to attach a parallel-printer directly to a SS5 at all?

There _may_ be a parallel port on the SS5, if there is it will be marked
thus: // (Some suns use a high density connector).

You can get an SBUS board and a dongle that has parallel ports on it too.

I have never actually used a parallel port on a sun, given all the
printers I have used were networked...

No! They're serial ports, like it says :-)

The parallel port has a high-density connector and is labelled //
and you'll need an adaptor cable to use it with ordinary parallel
cables.

Of course it's possible. You have just been looking at the wrong
connectors on the back of the Sparc 5.

The parallel port is one of the two small 26-pin connectors next to
the 10Base-T connector. It's the upper one.

You'll need a cable to adapt the "mini 26" connector to the connector
on your printer. Sun's part number for the cable is 530-1857 if the
connector on your printer is the Centronics style, or 530-1861 if your
printer has a DB-25 style connector.

As others have said, you need a special cable to access the parallel
ports. That cable is also used on an SS20, so when looking on eBay or
wherever for it, bear that in mind - it might be listed for an SS20. I
suspect it is the same part - but check. Those cables seemed to fetch
quite a bit.

I assume the printer is not a Postscript device, since most of those
are networked. If you do fix a non-Postscript printer, look at using
Ghostscript to printer to the parallel port, the printer is likely to
be non-postscript, as I think most Postscript printers will have a
network connector, which will be far less hassle.

Someone wrote a web page about doing using Ghostscript in this way,
although there was some comments that the method he used is not 100%
how Solaris intends printing to be done. He has put a note about that.

It wrote this script which seems to work for me, setting up an Epson
on a parallel port. Note it uses /dev/ecpp0, which is the port on the
Ultra range, not on the SPARC 5, which is /dev/bpp0. I'm not saying
the script will work unchanged, but it might give you an idea of how
to go about it.
I script does something to get different resolutions (fast, slow,
photo ..) options to Ghostscript. That part is broken, so ignore that.

The -dBuffer Space=250000000 allocates 250 Mb as a buffer which I'm
told speeds things up a bit. You are not likely to want to do that on
a SPARC 5!!

It uses a file 'psselect -r' to reverse the page order, so page 1 of
the document appears at the top. I think there is a Solaris command
that will do that, so you don't need psselect. But I happen to have it
installed and can't be bothered to change what works.

Anyway, here it is. It's not perfect at all, but possibly semi-useful.

Are these normal parallel-ports that I can put my printer in and what /dev/-names do
they get in openbsd? bpp0 and bpp1? I've tried to dump some raw text to those
devices but my HP Laserjet 1100 doesn't respond in any way. bpp0 is listed in dmesg
like this:


Ermm, as the label states, these are *serial* ports, not parallel! And yes, you
need a special cable to split the two ports from this one connector. The parallel
port is the other connector which is labelled: //

They look just like PC-style parallel ports but I guess it was a little to wishfull thinking to hope that they could be used as parallel ports :/
