Epson Stopped PrintingAn Epson that is holding a job it won't print refuses every other job too. Switching it off and on clears it in under a minute.
Server Direct PrintWhen Server Direct Print is on, an Epson turns away every job the POS sends while its own web page and self-test still work. Turn it off, or print through Cloud Print.
iPad & iPhone PermissionsOn an iPad or iPhone, a refused Local Network permission looks exactly like a printer that's switched off. Where to turn it back on.
Android PermissionsAllow Nearby devices so WCPOS on an Android phone or tablet can find your Bluetooth printer, and what to check when a Wi-Fi printer still isn't found.
Browser PermissionsChrome's local network permission, mixed content and the printer's certificate — the three things that stop a browser reaching a printer.
Receipt Logo MissingThe receipt printer prints everything but the store logo, and only from a browser. The logo's address is the cause; here is how to check it and fix it.
Receipt WidthRead the test page's ruler, pick 32, 42, 48 or 64 characters per line, and fix receipts that wrap, stop short of the edge or cut the logo off.
Non-Latin ReceiptsQuestion marks, boxes or the wrong letters on a printed receipt mean the printer is using the wrong character table. Set the receipt language, or print the receipt as an image.
