ZQ520: is there a cpcl command to download file to printer

Hi everyone,

As titled, I would like to download a PCX file to printer via "!U1 xxxx " command.

User Case:

Potentially, there will be over 800 printers running in our system all over country. We would like to do it via app which could send command to download image to printer instead of using Zebra Utilities.

The first input way in manual PCX command section will slow down the process.
