Graphical output - Print logo

[sysxlabs]

Hi Mike,

I am writing for another enhancement, I have a NV Logo uploaded to the printer memory, now I want to print that logo... If this functionality is already provided then I want to know the syntax for it.

When I send print from windows, the NV Logo is printed, but when I tried to print with this code, the NV Logo is not printing.

Thanks

Hi sysxlabs,

This feature is not currently available, but I'll take and see what would be required to add it. So that I can pull up the specs for it, what model printer you're testing this with?

[sysxlabs]

I am using EPOS TEP 220M. This printer is compatible with ESC/POS Commands

[sysxlabs]

Still Waiting for the update on this enhancement. I used this library on my EPOS TEP 220M and it's working beautifully.... but now stuck in this one issue... I am waiting for this library to get updated ASAP.

Maybe this article helps a bit:

Hey all, Unfortunately, I don't currently have access to a printer to do an implementation for this, so it's not likely to be done in the next few months.

It's definitely possible/worthwhile/well documented, and I'm happy to accept any pull requests which add the functionality.

While I wait for an Epson TM T20 to code proper bitmap uploads with, sysxlabs, could you checkout the testing branch and see if this test function works on your printer?

$escpos -> image_nv_print_test();

Basic image support is now available- you can print a local PNG file from the computer. NV graphics are not quite as straightforward, so I'll leave this feature request open.

You currently need GD to manipulate the images (package php5-gd in Debian).

Documentation:

• https://github.com/mike42/escpos-php#graphicsescposimage-image-size

Usage examples:

• https://github.com/mike42/escpos-php/blob/master/example/graphics.php
• https://github.com/mike42/escpos-php/blob/master/example/receipt-with-logo.php

And if it doesn't work with your printer, the older bitImage() command is also there as a fallback:

• https://github.com/mike42/escpos-php/blob/master/example/bit-image.php

For the NV graphics, there are several ways to upload and print them (older bitImage and newer graphics commands). I've made some progress on saving & printing bit images from NV memory, but the results are not satisfactory. So at the moment, I would suggest a direct print-from-PNG approach.

perfecto... this works like a charm

[mike42]

Good to hear.

Does the EPOS TEP 220M work with both graphics() and bitImage()?

Closing this one. NV graphics still not implemented but original enhancement was added.
