Unhappy cups takes forever to print images


hi

I use pxlmono with CUPS under linux to print files. When there is a file that contains an image... it takes forever! Bigger the image, worst it is.

anyone had this problem? how can I fix it?


It's annoying since Linux competes a lot with Windows in my environment, and windows doesn't have this problem.

The printing takes forever? or the processing prior to the data are ready and sent to the printer?
I could'nt help with the second one - but the first - this may be due to the settings of the printer-driver used - if it is set to very high quality and high resolution etc. then I know from my own experience, that cups is printing...very good but also really slow. I'm using cups and gimp-print as the driver - not sure how to do it with foomatic...but should be very similar.
Lower the resolution, change the dither-algorithm to something "lighter"

It's a laser printer. It takes about 2 seconds or less to get the paper out the machine once it's processed . not very long. The worst that can happen is that it's going out of it's "sleep" mode... then it takes an extra 15 seconds...


It's the processing that is really slow. Text documents are instantanious. However, images are about a minute or two. The quality is set to normal, and comes out good... for a black and white printer. But I'm just surprise that it takes so long compared to Windows.

I use foomatic because I had issues with gimp-print back when I used Mandrake (occasional failed printing, too slow, not stable, etcetc).

anyone else has suggestions? at worst I'll lower the resolution when I'm printing images meanwhile, and do my own benchmarking test

the most impressive speed gain I had was, when I changed the value of "dither algorithm" - together with "Image Type" - the first one to "Floyd-Steinberg" or "fast" (from the standard "adaptive hybrid" and the second to line-art (from "Photograph") - not sure, which one of them did the trick, but I think it was the faster (and less acurate - but not visible to me) dithering-algorithm.
There may be similar methods to tweak the output for foomatic...which in turn did not work well for my printer.
Before the channge it took about 2-3 Minutes to print out one page - no matter, what was on it - with these settings it comes out...just as fast as in Windows And there are no visible changes to the output - it is a Epson Stylus C40S inkjet

We have the ML-1450... using the "lpr" command seam to make a difference in the size of the document sent to the printer (4mb of RAM on the printer). Printing using the kprinter dialog with CUPS: 1500kb, with lpr, 500kb...

I'll try out your trick, sounds like that would do the trick...

I want to thank you

I tried to lower the "print out type" and that did the trick. A full page picture printed inside 5 seconds!

thanks

I have found printing to be one of the most annoying aspects of Linux. BUT---as I learn, I find that one reason is simply that there is more control. The downside of having lots of knobs to turn is that they don't always start where you would want them....
I have started using Turboprint, which is a big improvement. For example, with my Canon S600 inkjet, the CUPS default was too light. Turboprint provides adjustments to fix this in a flash. AND, it give you access to clean and nozzle check utilities.
