Java打印服务API：将作业发送到打印机假脱机？

Question

I am using Java print service API to select PrintService and then pass it to JasperReport 's JRPrintServiceExporter . The basic idea is to just send a document to the provided PrintService . It is actually using java.awt.print.PrinterJob.print() .

It seems like you cannot send a print job to a printer that has PrinterIsAcceptingJobs.NOT_ACCEPTING_JOBS attribute, when it is offline or powered off If I sent a job to it, I would get a PrinterException because it is not accepting jobs.

Is it possible to print to a "NOT_ACCEPTING_JOBS" printer? In actual operating system this works, the job is queued in the pool. How to achieve the same effect using Java print service API?

Answer 1

I think the problem you are trying to solve is similar to this bug . The problem seems to be that Java 1.5 and 1.6 looks at the wrong flags (printer instead of queue).

A solution that seems to work is to use the ForceAcceptPrintService described in this forum . Alternatively, this post mentions a workaround using byte manipulation but I didn't try that solution myself.
