So, I write PHP component, that can print documents via IPP (Internet Printing Protocol). But I can not print HTML document (text|html - mimetype) correct. Printer has printed this type as RAW. May be somebody give example of correct request (header and body)?
For example my incorrect request, that was printed as RAW data.

Even though e.g. CUPS advertises support for
text/html(see it's printer attributedocument-formats-supported) it's not converting html to e.g. postscript.You can not expect a printer or spooler to render HTML for you (like a browser would). You might want to search for a html-to-pdf converter as a workaround.
A typical and proper solution would involve a dedicated pdf-library for creating printable documents. The downside is you'd have to code the layout again.
Step 2 would involve submitting the job to the printer. It look's like you can handle this. If not check this answer. Also there's an IPP implementation for PHP available at http://www.nongnu.org/phpprintipp/
