Summary: Honor VT100 Remote Printing Sequences
Product: konsole
Version: 1.6.2
Platform: Ubuntu Packages
S/Version: Linux
Status: UNCNFIRMED
Severity: wishlist
Priority: NR
Component: general
AssignedTo: konsole-devel kde org
ReportedBy: fd0man gmail com


Version: 1.6.2 (using KDE KDE 3.5.2)
Installed from: Ubuntu Packages

Konsole does not honor the VT100 terminal requests for "start printing output" and "end printing output." Konsole does allow for printing of the screen contents at a point in time, however, it doesn't allow for remotely controlled VT100 printing (e.g., through Lynx or a custom printing script.

It should allow the user to print the raw contents of whatever is attempted to be printed, through to the printer (without filtering, if possible -- though I don't know if it is possible to by-pass the printer filters for things like text and the like). Ideally, if I'm ssh'd into a server somewhere through a Konsole session, I should be able to pipe a raw text file or PostScript document into a shell printing script and it should work.

The unsupported terminal sequences are "^[[5i" ("ESC [5i" -- Printing begin) and "^[[4i" ("ESC [4i" -- Printing finish). These can be found on http://astronomy.swin.edu.au/~pbourke/dataformats/vt100/ under the Printing section, named "Print controller off" and "Print controller on".

When the terminal receives the begin printing command, all future output should be directed to the printer set as the default on the user's computer, until the terminal encounters the end printing command. I will procure a test script shortly that can be used to demonstrate the functionality (or lack of, rather) of this feature in Konsole.

Michael,

The unsupported terminal sequences are "^[[5i" ("ESC [5i" -- Printing begin) and
"^[[4i" ("ESC [4i" -- Printing finish).

indeed the sequences are unsupported. , i did not include this command,
because i thought the application would be rare and chances are that you get a
deranged terminal it the printing-finish command does not occur. I would now hesitate
for other reasons, as i found virtually any application i learned about an to multiplex
the terminal for various purposes risking to stumble into security issues.

Normally, you can help yourself with the "tee" command.

Ideally, if I'm ssh'd into a
server somewhere through a Konsole session, I should be able to pipe a raw text file or
PostScript document into a shell printing script and it should work.

and this, i believe, is the point. Why not using a proper remote printer for your task?
