Oh my God.
Not only you use serial ports, which are outdated for printers for like 10 years.
You also insist on having the obsolete MS-DOS numbering for them, which is not important at all, if the device follows the “serenum” protocol.
It is a VERY good idea to switch to USB and use the standard USB printer support.
And yes, HyperTerminal is outdated too.
