The IRS beginning this month, eliminated faxing of transcripts. They will be sent by mail unless you request delivery to the IRS online mailbox. If you have a 2848, or 8821 on file, you can access the mailbox, which has a nice beaurocratic name, (Secure Object Repository [SOR]), by logging in on the e-services page. The login button is at the lower right of the page. They can then be downloaded, or printed.
It takes about 3 hours for the transcripts to be delivered to the mail box.
I find it superior than fax as they can be selected in order and also do not have cover pages.
