Is there a way to fix a PostScript file error?

I am using Print Distributor to write PostScript files to disk and then reprint them to a printer. When an error occurs no pages after the error are printed but the file size seems to reflect that all of the page data is there. Is there any way to find the error and fix it so I can print the entire file?

I am using GSView to view the postscript and the error I am getting now is:

ERROR: ioerror OFFENDING COMMAND: image STACK:

Any ideas?

It's a feature of PostScript that nothing in the job is processed after *any* error occurs. Hence the printer never sees the "showpage" command at the end. That is the way PostScript works, to ensure that what is printed is correct.

The only thing you can do is to download an "error handler" as part of the print job, like the Windows driver does. This then tells the printer to print an appropriate error message. If you write your own error handler, you could also tell it to print the data that was received prior to the error, by having the error handler issue a "showpage" command before it terminates.

There is always a way to fix problems... However, PostScript is a programming language, and if you don't work with it on a daily basis, chances are that there is nothing you can do to fix that problem yourself. Your best bet is to get in touch with the makers of this Print Distributor and have them debug your problem. They have the tools, and the knowledge to do this in a lot less time it would take you to even get started with PostScript programming.

Great. However, this only works when the PostScript generator creates PS that has self contained pages. That is not necessarily true: Because it is a programming language, you can do things on the first page that affect any of the following pages. See, you just learned one more thing about PS :) Great job. You can submit a request to have this question PAQ'ed and your points refunded.
