The bottleneck is almost certain= ly=20 > the print engine. esp. in graphics mode. It currently takes about 5 minutes to transfer a 20MB file to my printer which has 64MB of memory. Printing starts within 5-10 seconds of the upload being completed. If the parallel port is in interrupt mode, CPU is pegged to 100% the whole time. In polled mode, CPU usage drops, but the printing time doesn't decrease (and the ``parallel'' process is running the whole time). That's what made me think that the parallel port is probably the bottleneck. =2D-=20 Kirk Strauser --=-=-= Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) iD8DBQA/bFfi5sRg+Y0CpvERAngcAJ96w+9YG6jlqhDJ1nue85IWBUAv8wCfdDZs PuXpMUcNwC1MZ+RAqGjLDdQ= =EEZJ -----END PGP SIGNATURE----- --=-=-=--
