Title: [HELP] Share Printer
Post by: brunok on January 11, 2018, 01:03:44 PM

Hello,

I've implemented a boot environment via PXE and it's working!  8)


Now, I came up with another problem: Install local printer and share on the network.  :(
Is it mandatory to use CUPS?

I was able to install Zebra USB printer, but how do I share with the network?

For example, from an Windows machine, I need to print to the Zebra printer that is installed on a ThinClient via USB. How to make?

I was able to install through CUPS.
Zebra TPL 2844 with EPL2 driver from cups.

I can print from the cups management page, but i can't print through the network on another machine.

This error appears (On the CUPS page: localhost:631/printers/XXXX):

stopped
"Not usable font available"


In the CUPS log:

No viable font found
Ignored bad font "FreeMono"
No usable font available

Someone with CUPS knowledge who has been through this?

Which tinycore version and which architecture?

Is the ghostscript extension loaded?

What happens if you load a font extension, for example dejavu-fonts-ttf?

Hmm - I see the problem with x86, but not with x86_64.

I did see the problem with piCore, but I believe I fixed it, I just can't remember how  :(

loading dejavu-fonts-ttf does indeed make things work for me with Core-8.2.1, but is not required for things to work in CorePure-8.2.1, which is odd.

Note that I tested with cups connected to a network printer and printed a text file from the same machine

A comment in the  dejavu-fonts-ttf.tcz.info  file states:

... and calling fc-cache from startup script.

Maybe related?

I don't believe the problem is with fontconfig per se - there is a startup script invoking fc-cache in the fontconfig extensions in x86, x86_64 and armv7.

I don't really see why loading dejavu-fonts-ttf would fix the problem in x86 when luxisr ttf fonts are included in the Xlibs extension anyway and dejavu-fonts-ttf are not required in X86_64.

There is a circular dependency between freetype and harfbuzz in X86_64 that is not present in x86 to avoid bloat, but I don't see how this would affect things.

..and I also see that the error:

Code: [Select]

W [16/Jan/2018:17:34:04 +0000] [Job 1] Ignored bad font "FreeMono"
E [16/Jan/2018:17:34:04 +0000] [Job 1] No usable font available..occurs with x86 and Xvesa, but not with x86 and Xorg-7.7...

Edit: with Xvesa and Xorg-fonts, cups also works

Xorg-fonts added as a dep to the cups-filters extension
