Do you have a printer maybe an older one that you would like to print to from your phone or tablet? An inkjet or a black-and-white or color laser? Something even its manufacturer doesn't support any more? Or they want to force you to subscribe to some cloud printing service to use it?

You found an app that allows you to print to a network printer directly from your device. Yes on your home or office network behind your own router and firewall. There is no cloud nothing uploaded nothing sent out no registration no external service to depend upon: everything happens on your own internal network – between your device and your printer.

Just check that your printer understands one of the many supported printer languages directly:

- PDF
- PWG (IPP Everywhere)
- PCLm PCLmS (Mopria)
- Airprint/URF (Apple)
- PostScript
- PCL 3 GUI (Hewlett-Packard)
- PCL 5/5c (Hewlett-Packard)
- PCL 6e/XL (Hewlett-Packard)
- HP-GL/2 RTL (Hewlett-Packard)
- ESC/P2 (Epson)
- ESC/P-R (Epson)
- ESC/PAGE (Epson)
- GDI host-based (many)
- XPS (Windows)
- P-Touch (Brother)
- ESC/POS (Epson)
- StarPRNT (Star Micronics)
- TSPL/TSPL2 (TSC)
- ZPL EPL (Zebra)

and it's connected to your local network (or your device) using one of the many supported connections:

- Ethernet
- WiFi
- WiFi Direct
- Bluetooth
- USB OTG (On-The-Go)

and protocols:

- RAW (JetDirect AppSocket Port 9100 TCPmon)
- LPD/LPR
- IPP/CUPS (Linux or Mac)
- Samba (Windows)
- WSD (Windows)
- UPnP
- FTP

You can configure the printer manually or automatically with:

- Bonjour/Avahi/ZeroConf
- WiFi Direct/Mopria
- Bluetooth Smart/LE
- IPP/CUPS
- Samba
- WSD
- UPnP

The app adds all your configured printers to Android and they will be available for any app that's capable to print: be it an e-mail app calendar document editor game or whatever else.

The paid version in addition to removing the ads rewards your support with several extra features:

- use the server mode (see below)
- when you print several images to a page they are printed in a collage layout instead of a simple boring grid with adaptive sizes to show each image in full without cropping;
- you can select from several display (dithering) options to make printing both black-and-white and colored image material much more interesting;
- you can enlarge a smaller page to fit the page size of the printer;
- you can use non-uniform printer resolutions.

SERVER MODE: The app is also capable of the reverse operation: instead of printing to a printer on your network it can provide the print server that you can print to from your other network devices. Practically you can connect your printer with an USB OTG adapter to your phone (maybe to an older phone no longer used) and it will become a full-fledged print server supporting the protocols above accepting incoming print jobs from all your other mobile devices or computers too.
