HP ePrint email rejected — manage Allowed Senders, attachment size/type, subject/body rules, SPF/DKIM tips
Technician
• What is your printer’s ePrint address (ends with
@hpeprint.com)?• Do the bounces say “ePrint job failed”, “Mail System Error”, or a code like 5.7.1/5.7.0?
• Are you the sender, or is it a shared mailbox/forwarder (Gmail/Outlook/Exchange)?
• What are you sending — PDF, JPG, DOCX, inline text, multiple attachments, or ZIPs? Size roughly how big?
@hpeprint.com address. Every email bounces back with “ePrint job failed”. I sent a PDF (12 MB) from a work account that relays through our domain. Subject line was blank.
Technician
1) Allowed Senders: if the printer is restricted, only emails on the list print; others bounce.
2) Attachment rules: ePrint only supports certain file types (PDF, JPG/JPEG, PNG, DOCX, XLSX, PPTX, TXT, HTML). Password-protected or encrypted files are rejected. Mac “Print to PDF” with encryption also fails.
3) Size limits: large messages/attachments (often around 10 MB total) get rejected.
4) Email formatting: missing Subject, embedded images only (no attachment), or ZIP/RAR often fail.
5) Authentication: if your domain’s SPF/DKIM is broken by a relay/forwarder, ePrint may treat it as suspicious and bounce.
Technician
• Open the HP Smart app / HP Smart Admin account that the printer is claimed to.
• Go to your printer → ePrint / Email-to-Print → turn on Only allow from these addresses (if you want restriction) and add the work emails/domains.
• If you still have a legacy login, the option can appear under the older HP Connected-style ePrint portal as “Allowed senders”.
• On the printer, print the Web Services Summary / Info Sheet to confirm the current ePrint address and status (Web Services ON, ePrint ON).
Technician
• Add the real From: addresses (not just the forwarder) to Allowed Senders. Some relays rewrite the From or break DKIM, producing 5.7.x rejections.
• Send directly from your mailbox first — avoid forwarding/aliasing — to test authentication.
• Keep total email size ≤ ~10 MB to be safe; attach the PDF instead of pasting heavy inline content.
• Use a clear Subject line; attach supported types only: PDF/JPG/PNG/DOCX/XLSX/PPTX/TXT/HTML. Avoid ZIP/RAR, password-protected PDFs, or macros.
• If the PDF is large, export at 300 dpi or “Print to PDF (no encryption)”. Multiple small attachments are better than one huge file.
Technician
1) New email (no forwarding).
2) Add a short Subject like “Test print”.
3) Single PDF attachment around 500 KB–2 MB (no passwords).
4) Body can be plain text; avoid signatures with embedded images or tracking pixels for this test.
5) Send to
@hpeprint.com and wait ~1–2 minutes. If it prints, increase size gradually or add DOCX/JPG to confirm supported formats.
Technician
• ZIP/RAR are blocked; large PPTX can exceed ePrint’s message limit (keep total ≤ ~10 MB). Convert large decks to PDF or split into smaller files.
• The 5.7.0/5.7.1 DKIM bounce from marketing means the sender’s signature is invalid after relay. Either add that exact From address to Allowed Senders and ensure the platform signs with your domain, or bypass the marketing relay and send directly from your mailbox when printing.

@yourcompany.com) to Allowed Senders in HP Smart Admin. That’s cleaner for teams.As for content: ePrint can print the email body (plain text/HTML) and supported attachments. For consistent layout, attach a PDF. Rich signatures or multiple inline images may produce extra pages; keep the test minimal and move the real content into an attachment for reliability.
Technician
• Keep Web Services enabled on the printer; reprint the info sheet if you ever reset ePrint.
• Periodically review Allowed Senders and remove ex-employees.
• Standardize a “print profile”: subject present, 1–2 small attachments, PDF preferred, total ≤ 10 MB, no ZIPs/passwords, no tracking pixels.
• If using a marketing platform, ensure SPF/DKIM are aligned for the From domain or send from a mailbox that you control directly.

Quick answer: the accepted fix
Accepted fix when HP ePrint emails bounce: in HP Smart/Admin update Allowed Senders, send from a mailbox you control (Subject required), keep total size ≤ ~10 MB, attach a supported file (PDF/JPG/DOCX), and avoid ZIP/encrypted docs. If you see 5.7.x errors, correct your SPF/DKIM or bypass relays.
Why HP ePrint rejects emails (Allowed Senders, size & file types, SPF/DKIM)
HP ePrint enforces sender and content checks to protect devices. If Allowed Senders is enabled, only listed emails/domains can print. Messages over the service’s size limit or with unsupported attachments are dropped. Relays/forwarders can break DKIM or cause SPF misalignment, triggering 5.7.x rejections. Use direct sending, small PDF/JPG attachments, and keep a simple plain-text body.
How to verify a compliant ePrint email
Send a single PDF (1–2 MB), include a Subject, and no images in your signature. If it prints, add a DOCX or JPG. If a newsletter service fails with DKIM errors, send from your mailbox or align authentication before adding that sender to Allowed Senders. Print the printer’s Web Services info page to confirm the ePrint address and status.
HP ePrint — quick troubleshooting tips
Most “bounce back” cases are sender restrictions, file type/size, or email authentication.
Quick path: update Allowed Senders → send directly with a Subject → attach a small PDF/JPG/DOCX (no ZIPs/passwords) → keep total ≤ ~10 MB → fix SPF/DKIM if using marketing relays. This resolves the majority of HP ePrint email rejected issues.

FAQ
What file types and sizes does HP ePrint accept?
Use PDF, JPG/JPEG, PNG, DOCX, XLSX, PPTX, TXT, or HTML. Avoid ZIP/RAR and encrypted/password-protected documents. Keep total email size ≤ ~10 MB.
How do I allow my team to use ePrint?
In HP Smart / HP Smart Admin, open your printer’s ePrint/Email-to-Print settings and add users or your company domain to Allowed Senders. You can require only allowed addresses to print.
Why do messages from our marketing platform bounce with 5.7.x?
Relays and forwarders can break DKIM/SPF, so ePrint refuses the email. Send directly from a mailbox you control or align authentication and add that exact sender to Allowed Senders.
Does ePrint print the email body or only attachments?
It can print the email body and attachments. For consistent layout, attach a PDF rather than relying on HTML signatures or inline images.
