Sync Printers


I have set up a master raspberry pi which sends ssh commands to two slave raspberry pi which drive two printers.

I start a print on each slave through sending a print command to each pi through execute parallel-ssh command on the master. The command I send to each slave is the print command taken from localhost:9091/apidoc: it starts with “curl -X … http…”

If i print identical files on each slave they start in sync, showing slices at the same time but as the file progresses they become out of time.

Is there a specific reason this happens/ is there anything I am doing wrong / how can I fix this?


Just to note that I ssh over Ethernet.

Also is there a way I can activate a print using a different command from “curl -x GET … http/ … “
