Question

Seal

Good day to all.
Actually the essence of the issue is as follows, when sending a document for printing, it increases its volume (in the print queue) to a large extent and takes 5-15 minutes to print.
Everything goes to another printer connected over the network at once.
From 2 PCs everything prints without problems and instantly.
