Speed/processor performance

Re: Speed/processor performance

And then there is the Microsoft PCL6 Class driver that it will automatically install.

Re: Speed/processor performance

I can make a test with Adobe.
The FW is the newest, I bought from you but the machine already had all the newest, hehe.
Am using the latest universal driver from Ricoh. Not the dedicated driver for this machine though.
The webside stated that the universal driver was the prefered one I seems to remember. I'll check that though.

Edit: The webside do not say that the universal driver is the prefered one.

Sounds like this could be your issue.

You could install more than one driver to compare which one performs better for you.

Re: Speed/processor performance

Top remedies for slow printing are disabling WSD and using print as image in Acrobat. The processors on the MPC2051 are faster than on the lower end 03's.

Re: Speed/processor performance

All of the things that have worked for slow PDF printing for me over the years. Some have already been covered by others, but for the TLDR crowd:

1. Use the PostScript driver instead of PCL, if the option is installed on MFP.

2. LPR for the printer port with queue name lp (LP lower case). Ricoh used to always recommend this when I went to training many moons ago.

3. If you have access to full Acrobat, use the option to save the file as a Reduced size PDF.

4. If the PDF is from a scan, try re-printing it as a PDF and then send it to print, or try printing at 300 dpi instead of 600 or 1200, though you'll need PCL 5 for that low of a print resolution.

5. Make sure firmware and driver are up to date.

6. If an email attachment, save the file locally before trying to print.

7. Make sure Acrobat is up to date (not as much of an issue now that it's set to auto-update), but if someone is using an old version of it, slap their wrist and have them install a version from this decade (I've seen people desperately still trying to use Acrobat 7 or 8 that they bought years ago and wonder why they have issues with PDF's from newer versions).

8. Download the file again.

9. Change to vector graphics or raster in the driver, or vice versa.

10. If the PDF has had multiple edits made to it by the user, even just comments, try the Save as option and overwrite the existing file. Many applications leave older pointers and other data when you do a plain save. By doing a Save As you remove those and get a cleaner file.

Re: Speed/processor performance

Thanks for a ton of good suggestions!

This has now taken on at least as much of a learning/investigation issue as a print speed issue.
i completed printing out the ca 1500 pages last night.

I have now done some testing. Six pages gave 338MB sent to the printer. Took a little more than six minutes for the printer to process and print out. And only four of them had the suspect graphics. So, exactly 1 ppm print speed. Impressive.....
One of those pages gives 111MB sent to the printer. Takes 1min 40s for the data to be sent from pc/received at printer and then an additional ca 30 sec before the sheet of paper is pulled from the tray and printing started.

Printed with universal driver from Foxit reader over ethernet to the printer.
The single page is attached. The single page was created by printing out the actual page in the manual with CutePDF writer.

However that single page file created with CutePDF writer is only 900kB when sent to the printer and prints out pretty immediately. The file itself is 424kB.
If of interest, the schematic is from the landing gear system on an Airbus Super Puma AS332

More to follow...

Thank you for providing ZERO indication that you've actually tried any of the good suggestions.
We're already well aware that your printing is slow.

Re: Speed/processor performance

Tested printing out from the original file, one page, the same test page, with Acrobat. I only have the free Acrobat Reader version.
Acrobat only sends 6,7MB to the printer, takes about 20s to send data, thereafter printout starts immediately. So, a HUGE difference between Foxit reader and Acrobat reader!

I tested saving the file as. No difference when printing out with Foxit from the new file.

I dont think I have a raster/vector, at least I dont know where to find it
I dont have post script either.
FW/software is up to date.
I don't have full version Acrobat.

Havent tested with the PCL6 yet, will have a look at that later.

Edit. My "Save the file as" could not make any difference I now realise, as I only gave the file a new name. Would need full Acrobat to do as suggested.

In order to accurately judge results from testing any of your good suggestions I needed to establish the baseline, which page is slow printing, how slow, how much data etc.

Re: Speed/processor performance

If you let windows install the printer automatically, it installs the printer using the WSD port, rather than TCP/IP.
WSD is ALWAYS desperately slow -particularly with PDf's

I have installed the driver manually. It is using TCP/IP.

Re: Speed/processor performance

I found the Vector/Raster setting. Was set to Vector, changed to Raster.
With Foxit the test page data went down from 111MB to 26MB.
My pc needed 23s to compute the page/data, then 1min to send the data to the printer, printout started immediately thereafter.
This is with Foxit.

So, still very slow.

Acrobat with raster set takes 10s to compute, then 35s to send to printer, print starts thereafter. Data reduced from 6,7MB to 6,1MB.
So, Acrobat with raster set seems to be slower than with vector set. Vector takes only 2-3s to compute and between 20-25s to send data.

I think your expectations are a little high for this 15yr old printer?

Re: Speed/processor performance

So far I think I can say there is several different variables in play. This particular file/files is provided to me, there is nothing I can do like download again etc. I want to print out at highest quality so those printer settings are also set.
But still there are seemingly several other variables, the most influential found so far seems to be the Foxit reader which is not good at all printing those spesific graphics. Acrobat is much better. Raster set makes Foxit faster but still much slower than Acrobat. Raster set with Acrobat seems to be slower than with Vector set.

Several of the options mentioned is unavailable to me, like Post script, full Acrobat, file editing etc.

What is remains to be tested is the PCL6 driver.

Re: Speed/processor performance

Hmm, not really.
I know max ppm are only 20, at highest DPI/quality it goes down to about 11ppm with A4LEF, at A4SEF it is down to about 9ppm.

But, I wasnt expecting 1-2ppm for a significant portion of that 1.500 page manual I printed yesterday, that I do admit
However it might seem that the printer wasn't the only one at fault for that low speed.

And it is "only" 8 years old, was made in may 2013

Re: Speed/processor performance

PCL6 driver didn't make any difference either.

I think the pdf files from this manual maybe are badly optimized or compiled or something...
Foxit is extremely slow, Acrobat just very very slow.

What seems to make a big difference is to somehow re-save the file. Too bad I don't have the full Acrobat version to test that further.
However, I have saved to Cutepdf writer at 4000dpi setting (max dpi). If i try to print that pdf file out it is is MUCH faster, both with Acrobat and Foxit, with universal driver and PCL6, raster/vector.

I can barely see any difference in the printouts. Some text do maybe get a tiny little bit fatter, slightly fuzzy schematics actually gets sharpened up a little bit. Pictures I am not able to se any difference to.

The conclusion so far, pdf's can be a difficult file type for fast and efficient prints. For some files at higher settings with some readers it can be next to impossible to print those pdf's.
Changing reader, and even better, resaving the files with Cutepdf writer (or Acrobat full version if I had that) seems to be the most efficient solution for at least the files in this particular manual.
