- Does anyone have experience with connecting a ps printer to SGI
- boxes via the SCSI {1,2} bus ?
-
- I have a zippy Xante ps printer. It is quite fast, and I have
- it connected via a centronics port. I have a breakout box on the
- line, and I see lots of handshake activity. I think that the
- printer is out pacing the parallel port on large bitmap images.
- The printer ready line is can be trapped with no data on the data lines.
-
- This wonderprinter has a SCSI port, and is designed for direct connection
- to Apple machines.
-
- Any insight about connecting this to a IRIS ?
-
- What is the max throughput on the parallel lines ?
- What is the bottleneck in getting data out a parallel line ?
- The CPU wait line shows lots of physical io waiting, like the
- whole CPU wait bar is light blue (whatever that means!).
-
- What is the throughput on the SCSI 1 or SCSI2 bus ? What are the
- bottlenecks there ?
-
- Would it pay to write/debug a SCSI driver for this beast ? Is there
- lp scripts that talk/listen to the SCSI port ? What are the
- issues to connect a program to a SCSI port ? Kernel drivers ?
- I don't know if the printer will try to converse with the host
- via the SCSI port.
-
- Cheers!
