All three apps are free to download from the App Store and Google Play. Advanced features are part of an optional Pro subscription inside each app, priced in your local currency in the store. You can cancel a subscription at any time in your Apple ID or Google Play settings, at least 24 hours before it renews. ### Do I need a computer or printer drivers? No. Smart Printer prints straight from your phone over Wi-Fi using AirPrint, so there is nothing to install on the printer or on a computer. Your phone and printer just need to be on the same Wi-Fi network. ### Can I send a fax without a fax machine or landline? Yes. The FAX: send from phone app sends the fax over the internet to the recipient's fax number. You scan or upload the document, type the number and tap send. ### Which phones do the apps work on? Each app is available for iPhone and iPad on the App Store and for Android phones and tablets on Google Play. ### Who makes these apps? Smart Printer and PDF Editor are published by hrhelperg s.r.o. in Prague, Czechia. FAX: send from phone is published by HELPERG LLC. See About for addresses and contacts. ### Does Smart Printer work with my HP, Canon, Epson or Brother printer? If your printer connects to Wi-Fi and supports AirPrint, it should work. That includes most current wireless models from HP, Canon, Epson and Brother. Smart Printer supports over 10,000 Wi-Fi printer models in total. ### Do I need to install printer drivers? No. Smart Printer uses AirPrint, so no extra drivers or software are needed on your phone, printer or computer. ### Can I print without Wi-Fi? Smart Printer prints over your local Wi-Fi network, so the phone and printer need to be connected to the same network. You do not need mobile data or an internet connection to print a file that is already on your phone. ### Can Smart Printer scan documents? Yes. The camera scanner handles documents, IDs, passports, receipts, business cards and notes. You can edit and filter scans, save them in several formats, or print them straight away as a copy. ### Which file types can I print? PDF, DOC, XLS, PPT, JPG, PNG and TXT files, plus photos, emails and web pages. You can import files from Dropbox and iCloud Drive. ### Do I need a landline or a fax machine? No. The app sends the fax over the internet. The recipient receives it on their fax machine or fax service as usual. ### Can I fax to another country? Yes, the app sends to local and international fax numbers. Enter the number in international format, starting with + and the country code, for example +1 for the US and Canada or +44 for the UK. ### How do I know my fax arrived? Every fax shows its delivery status in the app. If a fax fails, for example because the line is busy, you can resend it from your fax history. ### Can I fax a photo or a document from my phone? Yes. You can upload a PDF or photograph the pages with the built-in scanner, which crops, enhances and converts them before sending. ### Is sending a fax secure? The app sends your document to the fax network over a secure connection. Bear in mind that faxes travel over the telephone network without end-to-end encryption, and the printed fax can be seen by anyone near the receiving machine, so check the number before you send anything sensitive. ### Can I fill in PDF forms on my phone? Yes. PDF Editor fills in PDF form fields, and you can add text anywhere on pages that have no form fields. ### Is an electronic signature legally valid in the UK? In England and Wales, electronic signatures are generally accepted as legally valid for most contracts, a position confirmed by the Law Commission in 2019. Some documents, such as certain deeds or documents that must be witnessed, have extra rules. If in doubt, ask the person or organisation that needs the signature. ### Does text recognition (OCR) send my documents online? No. According to the app listing, text recognition runs on your device. Some file conversions do need an internet connection. ### Can I convert a PDF to Word? Yes. PDF Editor converts PDFs to Word and back, and also handles PowerPoint, EPUB, TXT, Excel (CSV) and image formats. ### Can I password-protect a PDF? Yes. You can add a password to a PDF, remove one from a PDF you have the password for, and add a watermark. ### Can I print from my iPhone without Wi-Fi? AirPrint needs the iPhone and printer on the same network. Some printers create their own direct Wi-Fi network (often called Wi-Fi Direct) that you can join from Settings › Wi-Fi to print without a router. ### Why is there no Print option in the share menu? Some apps don't offer printing. Save the file to the Files app or open it in an app like Smart Printer, then print from there. ### Can I print from an iPhone to a printer that doesn't support AirPrint? Often yes, through the printer manufacturer's own app, which uses its own connection method. Check the manufacturer's website for an iPhone app for your model. ### Do I need to install anything to print from Android? Most recent Android phones include a Default Print Service that finds common Wi-Fi printers. If yours isn't found, install your printer brand's print plug-in from Google Play or use a printing app. ### Can I print from Android to a USB printer? Printing over Wi-Fi is the simple route. Some printers can connect via a USB OTG cable, but support depends on the phone and printer. ### Is a phone scan good enough for official documents? For most purposes, yes, as long as the scan is sharp, straight and complete. Some organisations ask for originals or certified copies, so check their requirements first. ### How do I make a scanned PDF searchable? Use a scanner with text recognition (OCR), such as PDF Editor, which recognises text on your device so you can search and copy it. ### Can I sign a PDF on my iPhone for free? Yes. Open the PDF in the Files app, tap Markup, then the + button and Add Signature. PDF Editor adds a signature library, form filling and more pen styles. ### What is the difference between an electronic signature and a digital signature? An electronic signature is any electronic sign of intent to sign, such as a drawn or typed signature. A digital signature is a specific type that uses a certificate and cryptography to prove who signed and that the document hasn't changed. ### Can I send a fax from my phone for free? Fax apps are usually free to download, but sending typically needs a subscription or credits, because each fax is delivered over the phone network. Check the price in the app store before you send. ### Can I receive faxes on my phone? Receiving needs a fax number of your own. Many fax apps focus on sending; online fax services offer dedicated numbers and an inbox for received faxes. ### Do faxes still count as signed documents? Many organisations accept a faxed signed document as a valid copy, but the rules depend on the organisation and the type of document. Ask the recipient if you are unsure. ## Sources - [Smart Printer: Scan Master Pro, App Store listing](https://apps.apple.com/app/id6746067890) - [Printer Smart: Scan, Print PDF, Google Play listing](https://play.google.com/store/apps/details?id=com.helperg.smart.printer) - [FAX: send from phone, App Store listing](https://apps.apple.com/app/id6760895885) - [FAX: send from phone, Google Play listing](https://play.google.com/store/apps/details?id=com.helperg.fax.app) - [PDF Editor: Scan & Sign Docs, App Store listing](https://apps.apple.com/app/id6747341672) - [PDF Editor: Converter Files, Google Play listing](https://play.google.com/store/apps/details?id=com.helperg.editor.documents) - [faxB2B, online fax for business teams](https://faxb2b.com/) - [PrinterArchive.net, reference library on printing and fax](https://printerarchive.net/) ## Publishers - hrhelperg s.r.o., Husitská 502/36, 130 00 Praha, Czechia (Smart Printer, PDF Editor, this website).
