Q: How do I send an email to a Printing Mailbox user? Do I need special software?

A: First, make sure that you are on the Printing Mailbox user's Presto Friends list. Then, you can send email just like you normally do. Simply address your email to the Printing Mailbox user's Presto email address. The Presto Service is compatible with most email clients and web services, including Microsoft Outlook, Yahoo! Mail, Gmail, Hotmail, EarthLink, Mail, Eudora, AOL, Apple Mail, and others. If your cell phone service offers email from your cell phone, we support that too.

Q: How do I let friends and family send me email?

A: Friends and family members must be added to the Presto Friends List so they can send email to your Printing Mailbox. There are several ways you can add someone to the Presto Friends list.

If you're the Account Manager, log in to your account at account.presto.com and select the Presto Friends List button. You can then add a sender by clicking on the Add an Email Friend button.

If you're a Printing Mailbox user, you can add people to your Friends List by using a Presto Friends Card. A sheet of these cards has already been printed on your HP Printing Mailbox. All you need to do is give one card to each friend or family member you want to include on your Friends List. If you have a lot of people to add to your Friends List, you can request more Presto Friends Cards at any time.

Account Managers and Printing Mailbox users can also add people to the Friends List by calling Presto Customer Care at (866) 428-0970.

Q: When are messages printed? Can I change the delivery schedule?

A: The Printing Mailbox can check for messages up to five times a day. You can either leave the default times, or you can quickly—and easily—change the time that the Printing Mailbox delivers your messages to fit your personal schedule and needs.

Once you’ve signed in to your Presto account (account.presto.com), click to select Printing Mailbox Settings. Once you’re in the Settings, look for—and choose—the tab that’s labeled Dialing and Time Zone. From here, you can select the delivery times that suit you best, plus you’ll be able to set your time zone. Before exiting, be sure and click Save! This will save your new settings to your Printing Mailbox.

Q: Can I attach files to my email? If so, what attachment types are supported?

A: Yes, you can! Presto currently supports email attachments in GIF, JPEG, and BMP formats. Be sure to check with your email service provider for any file size limitations that might apply to you.

Q: What type of digital photos and images can I send?

A: Presto currently supports GIF, JPEG, and BMP image formats.

Q: What happens to email that hasn't been delivered because the Printing Mailbox ran out of paper?

A: Don't worry: messages that didn't print because the Printing Mailbox was out of paper aren't lost. Once you've added more paper, the Printing Mailbox will resume printing messages.

Q: Can Presto users send email using the Printing Mailbox?

A: Presto users automatically receive email and photos without the cost and hassles of a computer and an internet account. Currently, Presto and the Printing Mailbox is a receive-only email service. Presto prints the sender’s phone number on each email that it delivers to allow the user to easily respond by phone.

Q: Can I reprint messages that are difficult to read or did not print because my Printing Mailbox was out of ink?

A: Unfortunately, no. Be sure to replace your print cartridge as soon as it starts running low on ink. If you'd like a reprint of a message, you will need to ask the sender to resend it.

Q: I sent an email to a Printing Mailbox user, and it came back as a non-delivered message. What should I do?

A: You must be on the Printing Mailbox user's Presto Friends list to be able to send him or her email. Please contact the Account Manager or the Printing Mailbox user so that they can add you to their Presto Friends list.

Q: Should I limit the size of messages that I send to the Printing Mailbox?

A: Your email provider may limit the size of files that you are allowed to send from your email address. If certain messages are returned to you, they may be too large. Please contact your email provider to verify whether or not an email file-size limitation exists. If you are still having trouble, you might try reducing the number of photos you have attached.

Q: What is a Presto Friends Card?

A: Each Presto user has an approved senders list. This is called a Friends List, and it controls who is—or is not—approved to send email to the user. This ensures the Presto user does not receive any spam, ads, or junk mail. The Presto Friends Cards are printed on the user's HP Printing Mailbox. The user then distributes these cards to friends and family members, who in turn add themselves to the user's Friends List, becoming approved senders. Once these quick, easy steps are completed, the user's friends and family can start sending email and digital photos to the Presto user.

Q: How many times can a Presto Friends Card be used?

A: Each Presto Friends Card can be used only once and each card only adds one person to the friends list. If you need more cards, you can request that another sheet of cards be printed.

Q: How can a Presto user request an additional sheet of Presto Friends Cards?

A: To request an additional sheet of Friends Cards, a Presto user can either call Presto Customer Care (866) 428-0970 or ask the account manager to request another sheet via the Account Management Website (account.presto.com).

Q: I was given a Presto Friends Card. How do I use it?

A: The first thing you'll need to do is to visit friends.presto.com. Follow the instructions on the page to become an approved sender.

Q: I already added myself to the Presto Friends List. How can I update that information?

A: In order to change your contact information, you must either contact the account manager, or ask the Presto user for another Presto Friends Card.

Q: I successfully added myself to a Presto Friends List, but the email I sent bounced back. What should I do?

A: First, make sure you are sending your message from the same email address that you requested be added to the Friends List. Each time an email is added to the Friends List, Presto sends a welcome email to the email address that you entered. If you didn't receive the welcome email, you may have entered your email address incorrectly. To correct this, either contact the Presto user and request a new card, or contact the account manager and request that your email address be corrected.
