Best precision printer

[stratman]

I found out that, in my printer, 1200dpi is a tad better than 600dpi and overall speed is exactly the same. Also, no toner waste as density of the image doesn’t change, hence the same amount of powder is used.

???

DPI is a measure of density of dots per inch. A DPI of 12000 has greater density of dots then a DPI of 600. While there may be caveats, when DPI is increased then there are more dots per inch and, therefore, more toner used.

This has been a nice debate, glad I started it.

By rights he should have been posted here: https://www.printerknowledge.com/forums/lexmark-dell-brother-inkjet-printers.13/
But I reckon it’s here now, so I’ll leave it…Enjoy..

Sorry but I don't agree.
What you say is correct for Canon inkjet printers where the ink droplet is always the same size, regardless of the resolution on the driver. It’s not true for laser printers where every dot of the image is formed by thousands of ultrasmall particles of toner powder, Hence, at 1200dpi dots are smaller than at 600 dpi. If the optical/mechanical precision of the laser engine would allow it, we might have real 2400, 4800dpi or even more, contrary to inkjets where ink droplet size limits the actual resolution.
In the case of laser printers more resolution doesn’t means more toner consumed, but more dots of smaller size. That is, four dots of 1200 dpi equals approximately the amount of toner powder required by one dot of 600 dpi.

You wrote in the first post that an offset of one millimetre was not acceptable, so how much is acceptable?

I made a small Lorem Ipsum document in MS Word and chose the same Arial Italic 8 pt. font as used by Arthur 5. The document prints the same in the free Libre Office program. I also made a ruler with one millimeter divisions by printing and scanning the grey engineering paper from https://www.papersnake.com/.

Using Irfan View I combined the words "Lorem ipsum and a ruler to estimate the offset. This is from my default printer, a Canon Pixma iP4300. Strangely enough the registration is better when printing from the cassette than when printing from the rear feed. Here is the combined 1200 dpi scans:

And here it is in 600 dpi scans for a comparison with Arthur5's text samples:

It looks like the offset is more like a tenth of a millimetre, would that be acceptable? If so a printer less expensive than the Canon Pro 10 could be used.

I have attached the Lorem document and the engineering paper in a zipped folder, to be used for comparing registration of other printers if you would like that. I have made the Lorem document in two versions with red and blue text, for easy printing the sample.

After posting those afwul results of the Maxify in "double pass" mode I thought that maybe I've been a bit careless aligning the paper.
I did the test again, this time trying to press the lateral guides as much as possible against the sides of the sheet. Results are much better. I don't know if squeezing too much the pack of sheets would cause intermitent problems -double feed, paper stuck, etc..
Anyway, in real life printing for 99% of people this kind of precision is irrelevant. Who cares if the text of one page starts 1.554 cmt from the left border and the next page at 1.573 cmt. ?

I think this looks very similar to my iP4300 cassette test, also an offset of a tenth of a millimetre or less. So with careful adjusting the paper guides good results can be obtained. I also adjusted the cassette paper guides carefully in the iP4300.

O’ you only waste your toner printing text at 1200 dpi,

Whether you believe it so or not…

Using excessive toner on text is just a waste, the human eye can only relate to text up to 300 dpi and anything higher than 300 dpi become invisible, put plan and simple we just can tell the difference.

If you use a higher dpi like 600 or 1200, all you are doing is laying down more toner and darkening the text, and if you’re using 3rd party toner that might be necessary because it’s not as black as OEM toner…

Proof of lasers ( at least my Brother HL-L5000d) eating aprox. the same amount of toner no matter which resolution.
Below you see some lines of text printed respectively at 300, 600 and 1200 dpi. and scanned afterwards at 1200 dpi
Do you think that 1200 dpi (third sample) is more dense than 300dpi ?. It looks rather the opposite,

Last image is an enlarged sample of the above text. 600 dpi looks much sharper than 300dpi, while 1200dpi is only marginally better than 600 but there’s still a difference.

Nope...
