stm32mp157 USB printer support

[xkun.1]

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.

Hi @xkun.1​ 

I think your hypothesis about the missing cups-filters package may be right but we currently don't deliver it through apt commands.

I am investigating to add this package into the OpenSTLinux apt repository. I will keep you posted.

Best regards,
