Frequently encounter font issues when using the Binarykits Nuget package

[gayathrijosyula]

We frequently encounter font issues when using the Binarykits Nuget package to convert ZPL to base64 content. When printing the labels, they do not appear in the correct alignment and font. A comparison with Labelary reveals the following differences in results.

can you kindly suggest solution for this, also can you tell me if Binarykits and labelary have font hardcoded.

[primo-ppcg]

The font is not hardcoded, and can be adjusted by supplying a custom font loader to the drawer options (example). If no font loader is supplied, Helvetica Semi-Condensed Bold will be used for Font 0, and DejaVu San Mono for all others, if installed.

I've corrected your ZPL by specifying a line count for the Field Block, and trailing it with a newline (this newline is necessary, or Labelary will not center it properly):

^XA
^FT175,110^A0N,90^FD. Fullartons^FS
^FT175,230^A0N,90^FDRM13 7XH^FS
^FT750,220^A0N,85,40^FDR-7001^FS

^XZ

On my local system with default fonts:

Labelary overlay in red.

The default line count for a field block should be 1, but it is overwritten to zero if provided an empty value. This is a bug that should be corrected (resolved with #174).

Thank you,i am using Binarykits.Zplk.Viewer version 1.1.3 still experiencing issue. However, when i check the using a link, it doesn't seem to be present.

This is the Zpl string i am using :

^XA^FT175,110^A0N,90^FD. Fullartons^FS^FT175,230^A0N,90^FDRM13 7XH^FS^FT750,220^A0N,85,40^FDR-7001^FS^FT175,340^A0N,45^FDOrder 3100000787^FS^FT750,480^A0N300,300^FB300,,,C,^FD1^FS^FT175,600^A0N,150^FD1/8^FS^FT750,570^A0N,60^FD05/07/2023^FS^FT750,600^A0N,30^FDLakeside Store (XP)^FS^FO175,350^BY2,3.0^BCN,80,Y,N,N,N^FD3100000787^FS^XZ

@primo-ppcg can you kindly help me with this please

[danzk]

The best approximation to Zebra Font 0 is Triumvirate Condensed Bold.

I don't quite understand the question. The result shown above is from running the viewer from my local system, not on Azure.

[gayathrijosyula]

Thank you :)
How are you able to obtain the displayed outcome when running the viewer locally, while I am unable to achieve the same result when running it on my own local machine?

https://binarykits-zpl-viewer.azurewebsites.net/

[primo-ppcg]

I mean I'm actually hosting the Viewer on my local machine:

You can clone the repository, and launch the Viewer.WebApi project from Visual Studio.

[gayathrijosyula]

I have incorporated this NuGet package into my local host code, but it is producing different results than expected.

[primo-ppcg]

You can check your local system that Helvetica Narrow Bold is installed. If not, you can install it, or specify a custom FontLoader in the DrawerOptions that are passed to the ZplElementDrawer.

[nazar-mykolyshyn]

Hello all, not sure if my question is related to this topic but I receive different versions of ZPL preview (I guess due to fonts) in https://binarykits-zpl-viewer.azurewebsites.net/ and local version running in Docker (https://hub.docker.com/r/yipingruan/binarykits-zpl using latest version (which is equal to dev-72 at the moment of posting). The azure one looks better

Do I need to supply some additional configuration to achieve the same result ? is docker image missing some fonts?
Thanks

[ivanjx]

anyone here know the exact font names used in zpl printers? the rendering below is using labelary viewer's initial script:

[ivanjx]

i fixed font 0 by loading it with Triumvirate Condensed Bold as suggested by @danzk. the font A is still off though.

[danzk]

Even labelary.com doesn't render font A accurately. You need a 5x9 pixel font like one of the following.
