Hello,

is there a possibility to use a HP Laserjet 1300 on a Sun
SPARCstation 10?
The jobs are staying in the queue with the status "ready and
printing" - but the printer doesn't print.
I think the problem is related with the ECP interface of the
new Laserjet. I'm pretty helpless. :-(
Any hint is greatly appreciated.

Regards
Kay

I had the same problem (SPARCstation 10 + Laserjet 1200). IMO the reason is
that the SPARCstation sets SELECTIN high, which causes modern printers to
assume that they were connected to an ECP compliant host (which the
SPARCstation isn't). I was able to print files using a small program which
writes to /dev/bpp0 directly and sets BPP_SLCTIN_PIN to 1 (SELECTIN is
active-low) via the BPPIOC_SETOUTPINS ioctl (see "man bpp"). I'm planning
to install CUPS on the machine, so I can patch the backend and include the
ioctl.
