how to convert a file to PCLmS print stream

[JayFang1993]

I'm doing some reasearch about IPP,My printer doesn't support application/pdf mime data,so I must send document-format with application/octet-stream,and I discovered cups convert source file to PCLmS print stream in Send-Document IPP request by Wireshark.

PCLmS print stream like this:

%PDF-1.7
%PCLm 1.0
%============= Job Ticket =============
%PCLmS-Job-Ticket
%job-ticket-version: 1.1
%epcl-version: 1.01

I don't understand all source codes of cups,could you tell me how to convert a file to PCLmS print stream,and in which source code file?

Thanks!

PCLm is a non-standard PDF-based raster format used by some HP printers and is not something that is supported by CUPS. You might check with the cups-filters project.

FYI regarding "what converts":

In general you may have a look at the section
"The Filter (includes the Driver)" in
https://en.opensuse.org/SDB:CUPS_in_a_Nutshell
and follow the links therein.

To find out "what converts" in your particular case,
inspect the CUPS log file as described in the section
"Usually provide CUPS debug messages" in
https://en.opensuse.org/SDB:How_to_Report_a_Printing_Issue

I guess in your particular case it is your particular printer
driver software that produces the PCLmS print stream.
