Print from hosting? #422

Closed krodo93 closed 7 years ago

krodo93 commented 7 years ago

Hello, I have my project in a hosting, can I send a print to a printer that is installed locally on my computer?

You can, but it's easier if you put it on the LAN. See Can I print from my server on the Internet?.

I would suggest checking out receipt-print-hq/chrome-raw-print, which I think will be built into a solution to this with time.

Printing on local will work well with this package.

However, to print online, you will need to develop a desktop service which has to be installed on the local computer where you need printing to be done. This is because PHP is a server-side scripting language, so once you put this online, it won't be able to communicate to the local printer. Thus, you need a client service running on the local machine and this is where electron js and node js come into play.

I resolved this by developing an electron js service based on node-escpos package which can receive commands from the online print command and then communicate those commands to the printer through USB.

Operating System does not matter in this case, you can be hosting on Linux based server and printing on a windows server. This desktop service interfaces between the online service and the local service.

You can check out the node-escpos printer driver package for some inspiration on how to go about this.

Check the FAQs on how to print online to have some pointers too.
