Telegram's own chat export lives in its desktop app, so a phone has no built-in way to print a chat. 2doc signs into your own Telegram account on the phone, turns the chat you pick into a dated PDF, and prints it through Android's print dialog. Nothing goes to us.
On paper, a Telegram chat keeps its structure:
The session stays on the phone until you end it, in 2doc's Settings or under Settings → Devices in Telegram. The sign-in and every import option are shown in the Telegram chat to PDF guide.
A group prints with every speaker's name on their messages. A public channel can be printed too: search for it and it appears under Public results, whether or not you follow it.
One section holds a limited number of messages. In a very busy chat the section keeps the newest and says so; a shorter period fits everything.
Print hands the document to Android's print dialog. Choose the printer, or Save as PDF for a file instead of paper, then the copies, paper size and pages. Only the print service you pick receives the file.
If the printer you want is missing, install its maker's print app. If the phone cannot print at all, 2doc says "Printing is not available": email the PDF to yourself and print it from a computer. The text messages printing guide has more ways onto paper.
Pick the days before you generate. 2doc shows progress while it reads older messages. Very old periods can be out of reach: then the section is marked incomplete instead of stopping short in silence, and a shorter or more recent period will be complete. Longer ranges are a Pro feature.
Everything on this page, printing included, with a free Telegram account. Pro is a single one-time purchase, with no subscription and no ads in either version. It unlocks longer date ranges, several conversations in one document, extra image layouts, and removes the "Created with 2doc" page footer.
No. 2doc signs in on the phone and makes the document there, so nothing has to be exported on a computer first.
A normal Telegram session on your phone, the same kind a second phone would get, listed under Settings → Devices in Telegram. 2doc reads the chat you pick, for the period you pick, and nothing else. The privacy policy has the details.
One chat per document is free. Several conversations in one document is a Pro feature.
Only to print voice messages as text, because Telegram does the transcribing. Everything else works with a free account.
