- I have been trying to write a program that will read the response of a
- PostScript printer on the parallel port on our hp 300/400s and 700.
-
- So far when I try to set things up on the 700s it fails in the
- io_reset call. Invalid argument?
-
- On the 300/400s I get past the io_reset and the io_timeout_ctl, the write
- works just fine but the read fails with io error. The read does fail after
- the timeout expires (I suppose that it is possible that the printer had nothing
- to say), but the error does not look like a timeout.
-
- Any ideas? Any suggestions?
-
- BTW The printer hooked up to the computer is a LaserJet II with a Pacific Page
- PostScript cartridge.
