With the green light flashing, it seems that the printer is not receiving the CTRL-D (EOF) character that it needs to print the job. The CTRL-D should be taken care of by the Windows PostScript driver. The only other things to check are:
- The parallel cable is bad. There have confirmed reports of bad parallel cables "disabling" the printer. You might want to try at least a couple different cables.
- Incorrect installation of the software. A very important step is installing the Windows Postscript driver from Windows Disk #6 (this is step 10 and 11 in Chapter 1, page 9 of the LaserWriter Select 310 User's Guide). The latest PostScript driver version is at least v3.53.
- A bad or incorrectly configured parallel interface card. Apple has heard that some cards have configuration DIP switches or jumpers.
- A bad printer I/O board. Does the test page print? Does the printer work if connected to a Macintosh?
