Durum

Evde bir mini pc var üzerinde linux calisiyor ve ona print göndermek istiyorum orada doküman kalmadan.

Temel

önce printer adini buluyorum

ssh user@remote-host "lpstat -p -d"

sonra

gzip -c /path/to/file.pdf | ssh user@remote-host “gunzip | lp -d PrinterName”

SSH keyim ilgili linux hostta mevcut , ve printer USB ile bagli

MacOs

Sag tik menüsüne eklemek icin Apps te “automator” aratiyorum sonra

Quick Action as Document type seciyoruz ve

workflow settinglerde bu ekranda ki ayarlari yapiyoruz

Sonra da su scripti ekliyoruz.
