A problem I have observed in the logs is that foomatic-rip calls
Ghostscript twice here. Once to convert the PDF input into PostrScript
and then to convert the PostScript into PCL XL.
Can you please try to set up your printer with the attached PPD file?
TRhe difference to the original is the following:

----------
I simply have copied the part which defines the Ghostscript command line
with the copy using the keyword "*FoomaticRIPCommandLinePDF:" instead of
"*FoomaticRIPCommandLine:". This tells foomatic-rip that the command
line is also vald for PDF input and no conversion to PostScript is
required.
If this solves the problem, I recommend to do this for all non-
PostScript PPD files.

Title:
Printing job in 16.04 is slower than in 14.04
Status in cups package in Ubuntu:
Incomplete
Bug description:
Ubuntu 16.04LTS
OS Version： 16.04.5
CUPS Version： 2.1.3
Ghostscript Version： 9.25 （2018-09-13）
Printing job in 16.04 is slower than in 14.04
We(RICOH printer driver developer) are report a problem from our printer
users:
I print file Ubuntu 14.04.5, CUPS 2.1.3,Ghostscript 9.25 is fast(12 Seconds).
But, after I update to Ubuntu 16.04, CUPS 2.1.3, Ghostscript 9.25, I
print the same file with the same driver is slow(326 Seconds).
I figure out that all the print jobs is much slower on Ubuntu 16.04.
I view the "CUPS Error Log", it shows that there are three points
which maybe the reasons that makes the print job slowly.
FIRST:
----------------------------------------------------------------------------
By counting the time from "Starting renderer" to "renderer exited with status
0", we figure out that 16.04 spend more time than 14.04 on "renderer" process.
So we assuming that："renderer" is one of the key process that makes the print
job slowly.
"Starting renderer with command: \"printf \'\\033%%-12345X@PJL
JOB\\012\';printf \'@PJL SET DATAMODE=TWIN\\ ........ @PJL
EOJ\\012\\033%%-12345X\'\""
.....
renderer exited with status 0"
----------------------------------------------------------------------------
SECOND:
============================================================================
On 16.04, a print job outputs lots of logs as below:
"[Job xxx] Removing document files."
This step(“Removing document files”)does not exsit on 14.04.
============================================================================
The phenomenon that print jobs slower in 16.04 is more obvious when printing
many jobs in the same time.
THIRD
We tried drivers form other company(HP,Brother…), the printings also slow
down in Ubuntu 16.04 than 14.04.
Our question is:
1. Do you have any plan to improve the performance of printing on Ubuntu
16.04?
2. Do you have any workaround before this problems fixed?
