This error is shown if you abort a job that is being imaged, eg by pushing
the Cancel-button on an Agfa Avantra imagesetter.
It can also show up when you send a page that is too large for the imagesetter
and the RIP still accepts the file but the imagesetter refuses to print
it and cancels the job. Sometimes making the page 0.1 mm smaller in both
directions does the job.
I have also seen the error on older PostScript level 1 RIPs when the
job being RIPped was to complicated for the system.
Another explanation is that you send binary data to a printer that can't
handle it - specifically Ctrl+C (ASCII 003). Check the settings of your
driver.
Corrupted data can also cause interrupt errors.
QuarkXPress 4.x will generate an "interrupt" error when you
print to a Xante Accel-a-Writer 3G from Windows 95 with the Adobe PS driver
4.24. Update the Xante firmware to the latest revision to get rid of the
error. |
