- I believe that the problem with Appletalk CheckSUM exist in all early
- Appletalk printers that uses Adobe Postscript Level2. I have seen and
- heard report from many about the same problem.
-
- I purhased PhaserIIPxi from Tektronix about 6 weeks ago and found out
- that it also has checksum problem. I refused to accept the printer
- until it is usable onmy appletalk network. It took about 2 days to
- convince tektronix that their ROM is bad and need update. 4 weeks
- later, I got my new ROM v2.03 (was 1.03b) and everything works now as
- it should be.
-
- Hope that helps.
