automate printer command testing

[hari]

Hi all,

I need to write a test script, which will automate the testing of
printer commands(specific to a POS printer). Is it possible to do this
without GUI. If without GUI, how can I send command to the printer(to
serial/parallel/USB) port of the printer.Some commands will have
response from the printer.How can I read that response.

My aim is to automate the printer command testing through scripts,
will any other scripts will be more efficient.


Thanks and Regards

Oy! Around 1990 was the last time I regularly used "chat script" systems.
Serial port communications programs such as Unix's HoneyDanBer UUCP
uses "chat scripts" per modem/device for
"send this" "look for a reply containing this" etc.
I don't recall if there were ways to test for error vs. success

ProComm's ASPECT scripting language provided that too.
Perhaps that'll do what you need? See

Ah, there is a general chat script program in Linux, see CHAT(8)
(Automated conversational script with a modem)
