Hi @EmbeddedTech ,
Thanks for your information.
So, if your pinter already supports the wifi, you can use the wifi method.
Today, I help you to check with wifi expert, and also get some information which may useful to you.
Your ublox is using the NXP 88W8987 chip, right? Then, you can use the SDK wifi client to connect your printer. Please check this SDK code:
SDK_2_10_1_MIMXRT1060-EVKB\boards\evkbmimxrt1060\wifi_examples\wifi_cli
After the connection, you need to find some network driver for your pinter, then migrate it to the RT SDK to driver your printer.
But, please note, we don't have the examples or application, the above is the thought, our expert told me the linux driver contains the network printer driver, you can migrate it by yourself. You also need to find your used printer matched driver.
Wish it helps you!
Best Regards,
Kerry
