Now the time taken to create the print file and send it complete to the printer is always going to be longer in linux with ghostscript employed than in windblows, that cannot be helped, the PCL5 to PCL3 conversion takes time, and in any case each individual computer is going to vary the time according to it's power to process etc.
I press the Okay button till the copy slides out, is 18 seconds for
Economy Grayscale, 23 seconds for Economy, 28 seconds for Normal Grayscale,
62 seconds for Normal, about a minute and a half for High Quality Grayscale, and about 4 minutes for High Quality. Normal and High Quality
probably aren't distinguishable by the casual viewer, but held side by
side Normal is slightly thicker and muddier looking. Under a magnifying
glass the edges would be fuzzier. High Quality has a slighter thinner,
harder, sharp-edged printshop look. High Quality Grayscale is just a
little lighter. Normal Grayscale is actually hard to tell from High
Quality, so I might switch to that as my default. I didn't test Very
High Quality or Photo or their grayscales. By the way, the times above
are for the first page, which includes the time it takes for the program
to communicate with the printer. I just ran page 1 and 2 at Normal
Grayscale and the first page was out at 28 seconds and the second at 51,
so all subsequent pages should take about 23 seconds apiece.
So how about taking a 600dpi scanned file in either .pnm or .jpg of an A4 colour page(it can be anything) then send that file to printer at say 600dpi High quality, and note the time from when the file first arrives at the spooling window (kde - peripherals - printer - jobs) and you start to hear the printer load the sheet of paper to completion of the printed page.
I created a 600dpi scanned A4 colour page .jpg file of 3.4Mb, in gimp, which took just over 3 minutes to print from the moment the page loaded to final ejection from the Lexmark Z53 printer. That's a lot of numbercrunchingbut sets a big task to compare performances with.
How long would your Epson C82 take to process the same size and type of file?
Sorry, don't know what an A4 color page is, nor how to create one. If you'll tell me how to make one in gimp I'll do it but I don't know how meaningful the print comparison will be. I don't use kde so will probably be printing from the command line. (Anything that's not being printed from OOo, Opera, or Pine.)

A4 is the page size , similar but not exact to American "letter" You don't have a scanner then ?
I just wanted to create a stand type size file to test that's all.
It could be something else, but an A4 page size colour scan to 600 dpi is going to create a large .pnm file and converted to .jpg in gimp would make a nice standard test file to print off in any programme you like, it's the speed of the printer under a linux driver that I'm interested in .The length of time the printer takes to complete a large standard print job.
