Delay during printing

How long is the delay? Are you printing color or mono? How big are the 100 documents with 1 page a piece? The printer states that it can have the first page out in as quick as 8.5 seconds (mono/black). That might be your issue if it is around 10 seconds of delay.

Well, a few thoughts on this.

1) The printer may be doing a calibration of some sort.
2) The printer's memory may be getting full, and it's taking a few seconds to flush the old jobs.
3) There may be some network latency
4) Since you are not using a spooler and printing directly to a TCP/IP stream, you may be having flow control issues, buffering issues, network retries, etc.
5) IMHO, it's a bit unreasonable to expect continuous printer duty; printers are going to run out of paper or jam at some point, do a calibration, need a reboot, etc. etc.

I would start with checking the printer settings, and making sure that job retention is turned off, etc.

Hi DrBob, hi Greg,
Thanks a lot for your help. It seems that there is no control for a continuous output. Depending on several parameters (temperature, humidity, coverage, etc.) the printer undertakes a cleaning and/or calibration. Cleaning usually doesn’t take too much time (3-10 sec.), calibration can last up to 1.5 minutes, users don’t have influence on this. The system tries to doe this between two print jobs and not during a multi-page document. That’s why a 100 page document, e.g., mostly will be printed without interruption, on the other hand with 100 single-page jobs the possibility of interruption exists.

Georg

Today's printers do their own housekeeping. So yes, your statement is correct.
It's what I said in a) in my reply.

I used to work for a medical equipment manufacturer.
Back in those days we bought color dot matrix printers by the truckload, to include with our most expensive and fastest systems.

The basic job was to print one page of mixed text and graphics, three times a minute, without causing a delay in our customers' lab operations.

I.e., we could not tolerate the printer shutting down or throttling the input for 'housekeeping' or anything else except running out of paper.

Only a few printers could actually do that, and they were constantly going in and out of production, or being 'updated', so we were constantly testing printers.
None of the printer manufacturer's reps that showed up at our big OEM account, even the most 'technical' ones, understood their own products' firmware and hardware well enough to predict with any certainty how well their product would work for us.

While print technology has advanced in clarity and (allegedly, speed), I suspect that printer producers have not gotten smarter since my time dealing with them.

You may need to build in or bundle a spooler, or test the printers you consider before contracting to buy them.
