Re: Remote outq vs. *DEVD

Timing that was reported to me was:

It took 2.2421 minutes to print a single facesheet. It took 1.0178m
from the time the print job was activated to when the printer even
began receiving the transmission. Then took another 1.2243 m to
process the information and print the actual documen.


The data sent to the printer to print a facesheet is minimal. The
printer uses a forms chip to create the form and fill it in from the
data stream. This is almost always a double sided form with supplied
data for both sides. I think I counted the number of lines sent as
being 33 lines of text. Longest line is 40 characters. Shortest line
is 1 character.

Run wrkshrpool, shows *SPOOL as a defined size of 439.56 M, Max active 33.

Don't know, yet, if pool is faulting.

How long is "too long?"

Are you by chance printing with overlays?  If so, and if the printer is merely an AFP printer, the iSeries must build a bitmap of each page being printed and send it to the printer.  If you use IPDS, with an IPDS-capable printer, the overlay is sent to the printer once, and married to the variable data as each page flits past-- must faster!  There are stand-alone IPDS interfaces-- one is a device much like a jet-direct box for a single printer, another handles 3 printers.  Unfortunately, I can't recall the manufacturer's name at the moment!

Of course, this difference in speed mostly affects remote locations with long communication lines.  Generally,  locally-attached AFP printers can handle limited amounts of overlay traffic without slowing things down too much.

If the device is a network printer (ie it has its own IP address) it should work better than a remote outq.  Remote outqs don't have some of the controls to start printing and a certain page, hold and restart, etc. (I think multiple copies may be affected as well, but don't quote me!).
