I found that choosing the CUPS+Gutenprint driver speeds up the printing
tremendously and reduces PCL errors to zero. So I suggest to set that
one as default instead of "Samsung ML-4600 Foomatic/pxlmono
(recommended)", which at present installs automatically.
Does this apply to other printers as well?

Title:
printing docs with images is very slow - PCL printer
Status in cups package in Ubuntu:
Fix Released
Bug description:
ubuntu 18.04 - Intel Xeon 8 core workstation - default driver for
samsung ML-4600
The printer is an old Samsung ML-4600 USB laser printer, but it does
its job. On a 8core workstation, printing starts immediately if it's
text only. The print itself is always done in 10" or so.
A 26kB LibO doc, containing a tiny 8k image only, needs 2min 6" till
the printer starts printing. With a 900kB image in the doc, the time
is exactly the same.
With scribus and the tiny 8K image, it takes 45s till the printer
starts action.
When trying to print a heavy 2MB per page PDF doc, it takes more than
10 min till the printer starts to act.
Odd - with top I cannot see any printing activity causing relevant cpu
load, but I think at least one core should do heavy rasterizing work.
I love linux to support old hardware - but this is not state-of-the-
art, hope improvements are possible.
Cheers,
Wolf
