stm32mp157 USB printer support
Hello,
I need use STM32MP157 connect a USB printer. I followed this article(https://community.st.com/s/question/0D53W00000cSjHuSAK/stm32mp157dk2-printer-support?t=1630032775565), and the result is right. but when I use print command like (lp printer_test.pdf), the printer not work. And the console outputs the following information: lp: Unsupported document-format "application/pdf".
Is it because I didn't install cups-filters, or any other else?
Please help me. Thanks.
Shaw.
