Title: Spooling?
Post by: Maarten van Goga on January 07, 2022, 11:59:21 AM
The Help-PDF gives some advices about the settings for 'spooling'. [In my version at page 92]

I've some questions;
The default location (Windows) = C:>Windows\System32\Spool\Printers.
Assuming space is not the problem, does the type of drive matters. Traditional HDD, SATA SSD or NVME SSD?

How big will an average spool print job (in Gb) be?

I've 128 Gb on my machine, so a software RAM-disk is also a possibility. See for background information:

Type of drive makes no difference.  The size of the spool file is highly dependent on the type of printer and what you are printing.  For example, if you have a wide format printer and you are printing 40x60 inch prints, that's a big file.  If you are printing 8x10 prints on 8.5 x 11 paper, that will be smaller.  The current printer driver resolution matters too: 300, 360, 600, 720, etc.  You can calculate it yourself if you like.  An 8x10 print at 600 PPI would be (8*600)*(10*600)*3=86 MB.  A 20x30 inch print at 720 PPI would be (20*720)*(30*720)*3=933 MB.  And if you are printing two of them in your job, it's twice that: 1.8 GB.  And so on.  That's how much data Qimage is sending to the driver.  There is some overhead in the spooler that will make the spool file a bit bigger than that but those numbers will get you in the ballpark.
