The image in the PDF is blurred when the printer is called from the command line to print it #604

When I used this command "lp -d ricoh -n 1 -o sides=one-sided -o ColorModel=Gray -o resolution=600dpi -o print-quality=5 -P 1-1 /home/print/shell/../printer/print_file/address.pdf", the image on the final printed file was fuzzy. There was no problem with the printer itself. When I used Windows Chrome to print the same file, the image was not fuzzy. How can I find this problem and fix it? I installed cups2.4.10, cups-filters, libcupsfilters, libpdd, ghostscripts10.01.0, all compiled and installed

The system is Ubuntu 22, and I installed all the open source fonts of Google fonts into the system.

It would help to have the PPD file for the queue (/etc/cups/ppd/ricoh.ppd) and a debug error_log file (run cupsctl --debug-logging, then print something, then attach the /var/log/cups/error_log file).

Hmm, so this queue is using Foomatic, transferring over to cups-filters...

Yes，I also found this point, which is used by the Cups-Filter compilation installation by default. So，The image is blurry because of this, how can I fix it？
