By the very definition of VTxxx Controller-Print and Auto-Print modes
they are not transparent. Controller-Print sends most data to the printer
but not all. Auto-Print copies the current terminal line to the printer
after a LF or VT.
The notion of using the print mechanisms as a way of performing Binary file
transfers is not well thought out. It might work assuming that you have
a perfectly clean line. But then you would not be going through any terminal
servers, telnet sessions, ....
Even in that case you still have to worry about flow control, and hope that
no data is lost along the way. A straight print dump gives you no way to
verify that the data is complete.
---
If you want to perform file transfers, use a file transfer protocol.
If you can convince your Web-Browser to auto-print a downloaded file, then
it should be trivial to convince it to auto-transfer a file using Kermit's
APC mechanisms.
