How to solve MCP30 POS Receipt Printer connection problems on iPad?

[cellardoor]

Hi, 

I purchased a Star Micronics MCP30 POS Receipt Printer from Officeworks (Australia) as it was the only one that I could purchase last minute. I'm having a lot of trouble connecting it to my Shopify POS on 9th Gen ipad. Purchased a USB printer cable as this was in the instructions (with a USBA - lightening adaptor).

Any ideas, tips or suggestions???

Thanks, 

Julie
