I've seen so many problems with Cyrillic in my life, believe me. I've seen PDFs with some Cyrillic glyphs replaced by garbage, and much more of such weird stuff than I wish to see. >=20 > Thanks for posting the _solution_ to your problem.

I'm currently hacking the Linux LPR "driver" for this printer (hll2340dlpr-3.2.0-1.i386.deb), and maybe (just maybe) I'll be able to figure out what Linux sends to it to enable ascii LPR printing. In this package, there is a promising small linux binary which Linux uses as an if=3D. I guess it has magic within. >=20 >=20 > > Now two questions are left: > >=20 > > 1.

I wish I knew how to add something to Firefox's print dialog!=20 Do you? --=20 Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/ --zhXaljGHf11kAtnf Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJesandAAoJEA2k8lmbXsY0zuEIAI0KY6XTzQiUgqAFVwbBnCKw vAFWt8BtF05jsfbwtdZTUbxw+yGHN6r76Y/qONcWJ7rfV7UjF190zJm9rbq9O+m3 ObjtpXIGCFz191snZE4ua8kXd46268r3WQvMtNb8sR6nM4oi6J41IjrCf4chBEXg 2oA6PKBxP4FkNbnkrcxu9Q7z2FqpUsuE8g5taCLh9BQxS63/FU8a5ubc4U8XYpki JDse+Ik3OkyR6hZii0Zablsb67b9Rwq94eAQ3mBZi3DR7lCsXY+4Argm5/gvsfZf WURLXfZEIFymyAKa2LxHrdEXWCxlGYStEIk/KcmF5nVWFulz3Qx+BnC6zUTEV7E= =rHbg -----END PGP SIGNATURE----- --zhXaljGHf11kAtnf--
