I've just purchased an officejet 6600 to replace a P1505 that died after many years of faithful service. I'm pleased with the 6600, especialy the eprint capabilities. I'm, however, very dissapointed that HP thinks so little of the environment that the 6600 does not support manual duplexing. I used that facility regularly on the P1505. I may not have saved a forest, but probably save at least part of one tree. I guess HP doesn't care about trees.
