The great yad hacking thread

lpstat and lpadmin may be what you need. For example, get a list of printers with

lpstat -e

johnraff · 2019-11-27 02:30:28

@achim you are aware of the utility system-config-printer?
https://packages.debian.org/stretch/sys … ig-printer
It's not yad, but might already do what you need...

achim · 2019-11-27 15:18:21

@damo
lpstat: Error - unknown option "e".
lpstat -v reads printer information. I do not yet know how to transfer the printer names to variables.

@johnraff
I've already thought of that. However, I would prefer a separate function under yad.

Many greetings

Works for me on Buster.

Example idea

### read printer devices
$ lpstat -v
device for Brother: dnssd://Brother%20HL-3140CW%20series._pdl-datastream._tcp.local/
device for Brother_HL_3140CW_series: ipp://BRW2C6FC9166C82.local:631/ipp/print
device for Brother_HL_3140CW_series_jem_laptop: ///dev/null

### put the 3rd fields in an array
$ arrPRINTERS=($(lpstat -v | awk '{print $3}'))

### format result (make a loop if there are more than one)
$ PRINTER_1=${arr[0]%:*} && echo "$PRINTER_1"
Brother

@misko_2083

Thanks, that's very good. This enables me to build a complete printer dialog.

@damo

The example does not work for me unfortunately. Or I just do not understand it?

I don't know - you haven't said what you have tried. Post your commands and the output?

achim · 2019-11-29 11:15:01

@damo

I just can not manage to formulate a loop that will give me a usable result. For it works now with this command:

lpstat -a | awk '{print $1}'

Nevertheless, many thanks for your support

PS. Maybe you have just told me how to formulate a loop with result from your proposal.

Hello Achim,

look at the thread in forums.linuxmint
I think i got a solution ........

Quick yad hack to loop through printers, and display your choice

#!/bin/bash
##
## yad-printer.sh

arrP=($(lpstat -a | awk '{print $1}'))

LIST=""

for ((j=0; j<${#arrP[*]}; j++));do
    p="${arrP[$j]}"
    [[ "$p" == "reason" ]] && continue
    LIST="${LIST}FALSE $p "
done

RET=$(yad --list \
    --text="Choose a Printer:" \
    --checklist --width=400 --height=200 \
    --column="Choose" --column="Printer Name" $LIST --separator=":" \
    --button=gtk-ok:0 --button=gtk-cancel:1 \
    )

if (( $? == 1 )); then # cancel button pressed
    exit 0
else
    printer=${RET%*:}
    printer=${printer#*:}
fi

echo -e "\n\tDo what you want with $printer!!\n"

(NB No error checks, and multi-choice is possible, but it was a quick try)

achim · 2019-11-30 01:42:02

@damo

A big thank you, now I save a lot of time and do not need any more experiments. An error check I will install.

@secureIT

one reads again and again that the TE wants to close the thread without good reason. That's why I'll do better for myself. I still have many interesting ideas.

Hi,

the content of the variable "sprint" is the default printer. Is it possible over this code

RET = $ (yad --list --center --fixed --title = "Printer" --window-icon = "gtk-print" --text = "\ n Currently '$ sprinter' is the default printer \ n \ n The following devices are available: \ n "\
     --radiolist --width = 550 --height = 350 --column = "Check" --column = "printername" $ LIST --separator = ":" \
     --button = gtk-cancel: 1 --button = gtk-ok: 0
     )
dvar = $ (echo $?)

to display the corresponding line as "activated"?

damo · 2019-12-01 21:37:11

From

man lpstat
...
-p [printer(s)]
            Shows  the  printers  and  whether they are enabled for printing.  If no printers are specified
            then all printers are listed.

This gives output such as

lpstat -p "Brother"
printer Brother is idle.  enabled since Thu 19 Sep 2019 08:32:47 BST

So use a test for the output

if lpstat -p "Brother" | grep -q 'enabled';then echo 'true'; else echo 'false'; fi

You could add something to the name in $LIST eg

for ((j=0; j<${#arrP[*]}; j++));do
    p="${arrP[$j]}"
    [[ "$p" == "reason" ]] && continue
    if lpstat -p "$p" | grep -q 'enabled';then
        p="$p ACTIVE"
    fi
    LIST="${LIST}FALSE $p "
done

NB Untested!

achim · 2019-12-02 15:36:41

@damo

I believe that I mispronounced myself in my post # 175. The variable "sprint" already corresponds exactly to the printer "EPSON_WF-3520_Series". When the YAD code is called, this printer is already set as the default. In the YAD window, however, all printers are displayed as "False". EPSON_WF-3520_Series True, but false for all others?
I had a test, because with --column "record number" and --hide-column = 2 two additional columns were inserted. These controlled the display of True and False. Unfortunately, the code did not work.

Without seeing your code it seems pointless trying to troubleshoot it!

achim · 2019-12-02 19:09:21

sorry...

stdr () {
lpstat -d > /tmp/sdr
 sdrucker=$(cat /tmp/sdr)
 sdrucker=${sdrucker%*:}
 sdrucker=${sdrucker#*:}
 echo $sdrucker
 }; export -f stdr

arrP=($(lpstat -a | awk '{print $1}'))

LIST=""

for ((j=0; j<${#arrP[*]}; j++));do
    p="${arrP[$j]}"
    [[ "$p" == "reason" ]] && continue
    LIST="${LIST}FALSE $p "
done

stdr
#if lpstat -p = $(cat /tmp/sdr) | grep -q 'enabled';then echo 'true'; else echo 'false'; fi

RET=$(yad --list --center --fixed --title="Drucker" --window-icon="gtk-print" --text='<span foreground="blue" font="12">Aktuell ist "$sdrucker". Zur Auswahl stehen die folgenden Geräte:</span>' \
    --radiolist --width=550 --height=350 --column "Select" --column="Druckername" $LIST --separator=":" \
    --button=gtk-cancel:1 --button=gtk-ok:0
    )
dvar=$(echo $?)										# Exit-Code auswerten
	
if [[ $dvar == 1 ]] || [[ $dvar == 70 ]] || [[ $dvar == 252 ]]; then	# Taste Abbrechen gedrückt || Skript-Ende mit [X] || Skript-Ende mit [Esc]
exit

I don't see a variable called "sprint" ??

achim · 2019-12-02 21:00:34

Oh, Variable "sprint" = Variable "sdrucker". "sprint" is old.

My TRUE/FALSE test was failing at first because $sdrucker was saved with a leading whitespace.

I don't see any need to export a function result, and have a tempfile.

#!/bin/bash
##
## yad-printer.sh

arrP=($(lpstat -a | awk '{print $1}'))

sdrucker="$(lpstat -d)"
sdrucker="${sdrucker##* }"   # get string after last whitespace

LIST=""

for ((j=0; j<${#arrP[*]}; j++));do
    p="${arrP[$j]}"
    [[ "$p" == "reason" ]] && continue
    if [[ "$p" == "$sdrucker" ]];then
        LIST="${LIST}TRUE $p "    
    else
        LIST="${LIST}FALSE $p "
    fi
done

RET=$(yad --list --center --fixed --title="Drucker" --window-icon="gtk-print" \
--text='<span foreground="blue" font="12">Aktuell ist "$sdrucker". Zur Auswahl stehen die folgenden Geräte:</span>' \
    --radiolist --width=550 --height=350 --column "Select" --column="Druckername" $LIST --separator=":" \
    --button=gtk-cancel:1 --button=gtk-ok:0
    )
dvar=$(echo $?)										# Exit-Code auswerten
	
if [[ $dvar == 1 ]] || [[ $dvar == 70 ]] || [[ $dvar == 252 ]]; then	# Taste Abbrechen gedrückt || Skript-Ende mit [X] || Skript-Ende mit [Esc]
    exit
else
    PRINTER=${RET%*:}
    PRINTER=${PRINTER#*:}
fi
echo "Chosen PRINTER= $PRINTER"
exit

Fantastic, it works. Sometimes the problem is so close you just can not recognize it. I spent a lot of time searching. Thanks again, I hope I can return the favor
