Which driver? How is it connected? (USB, wired ethernet, wifi?)

Let's see which CUPS backend is in use...

Code:

lpstat -t

This should help with determining the driver in use...

Code:

egrep -i "name|filter|model" /etc/cups/ppd/*

Examination of the CUPS error_log might yield more clues too.

I used to have this problem on Debian 8 or 9, it turned out to be a conversion from the original format to some sort of postscript document... sorry I don't have the details.
Which version of Mint?

Ok, so the printer is using the Samsung PostScript driver. I recall seeing similar behaviour when using a postscript driver to print to a Samsung office printer several years ago. Not sure that there's much that can be done here.

Thanx... ill look at it soon... feels like "some buffer" are very full... but I cant se anything with low memory...

It's more likely some insane processing in the filter chain. FWIW, here's an old bug report describing similar behaviour ,and there is an indepth discussion about PDF document processing. It will give you an insight about what might be happening under the hood.

I'm pretty sure that's what I've been experiencing myself.

OP, you can check by leaving a terminal window running 'top' open at all times - it will show you what's eating resources.

I'd think that it is more of an issue booting to a usb drive and trying to print to a usb device. There could be a lot of traffic on a laptop usb port/controller. By default a laptop isn't very powerful.

If you had a toram option (some go by other phrases) then try it again or try a live optical disc.

The computer is 300km from me and i have not possibilty to be there often..
I installed it at an SSD-disc instead of USB-stick but it didnt solved the problem... I have to sit down some day and fix it... I have TeamWiever installed now so I can do some job from my home...
Tanks so far... Ill be back
