Nope, not right now (Also not environmentally friendly lol) but what do you need it for ? Print out ce lua script, or use ce's lua to print stuff ? _________________ Do not ask me about online cheats. I don't know any and wont help finding them. Like my help?

I need to print out some result from some variables and tables.

Example:

Code:

player_table = {
{v_name = 'John", v_hp = 1000, v_spell = 500, v_country = "Sky Kingdom", v_image = "john.jpg"},
{v_name = 'Watanabe", v_hp = 1500, v_spell = 500, v_country = "Sea Kingdom", v_image = "watanabe.jpg"}
}

function GetplayersInfo()

idx = playerCB.ItemIndex --- a comboBox

if idx <= 0 then return nil end

showPlayerPanel() --- show player panel on screen

pSearchPlayerBox.Text = player_table[idx].v_name
pHpBox.Text = player_table[idx].v_hp
pSpellBox.Text = player_table[idx].v_spell
pCountryBox.Text = player_table[idx].v_country
pImageBox.Text = tab_recipe[idx].v_image

btnPrintPlayerInfo.Enabled = true
end

function printPlayer()

test = [[
--- here to print the player info output to printer eq:
plyrInfo = [[
................ Player Info ..................
-----------------------------------------
Player name = ]]..pSearchPlayerBox.Text
[[Total HP = ]]..pHpBox.Text
[[Total Spell = ]]..pSpellBox.Text
[[Country = ]].. pCountryBox.Text
]]

-- mean while I am use

plyrInfoFile = io.open(pSearchPlayerBox.Text..".txt"', "W')
plyrInfoFile:write(plyrInfo)
plyrInfoFile:close()

end

playerCB.OnChange = GetplayersInfo
btnPrintPlayerInfo.OnClick = printPlayer

I think there are a Lua module to print string to a PDF file also and this one below just print Lua Engine result to console.

Code:

local out = io.popen('find /v "" > con', "w")

function print(s)
out:write(s.."\r\n") --\r because windows
out:flush()
end
print("It really works this time!")

There are command line tools like Windows 'print' that can be used to send things to the default printer. Combine that with Lua's normal file I/O and you should be able to achieve this via os.execute. _________________ - Retired.

Yes atom0s, I can use something like:

Code:

cmd = [[print c:\file.txt /c /d:lpt1]] -- or use other print arguments
os.execute(cmd)

But, the windows print command arguments only allow printer port COM and LPT, beside shall not show printer options.

So, I decide make a simple HTML page with print option on it, example:

Code:

p_name = " >>> Corroder The Cheater Slayer <<<"
p_decs = 'A man with golden gun with infinity ammo'
p_cat = 'Hero'
p_country = 'The Sky Kingdom'
p_gen = 'Male'

p_items = [[
500 HP <br>
1000 FP<br>
250 Spell Items<br>
2 Golden Guns<br>
1 Sharp Golden Magic Sword<br>
1 Bow Arrow<br>
2 Knives<br>
Re-custom uniform<br>
]]

p_abi = [[
1. Able to flying for 3- seconds<br>
2. Give 200 damage points<br>
3. Move slow<br>
4. Eat too much<br>
]]

scr = [[
<!DOCTYPE html>
<html>
<body>
<div style="width:600px; height:620px; padding:15px; text-align:left; border: 10px solid #787878; background-color:DarkSlateGray">

<span style="font-size:15px"><i>Perform by : Corroder - Hero Card</span>
</div>
</div>
</body>
</html>

<input type="button" value="Print this page" onClick="window.print()">
]]

local function show_html(htmlscript)
local encoder_table = {}
for _, chars in ipairs{'==', 'AZ', 'az', '09', '++', '//'} do
for ascii = chars:byte(), chars:byte(2) do
table.insert(encoder_table, string.char(ascii))
end
end
local function tobase64(str)
local result, pos = {}, 1
while pos <= #str do
local last3 = {str:byte(pos, pos+2)}
local padded = 3 - #last3
for j = 1, padded do
table.insert(last3, 0)
end
local codes = {
math.floor(last3[1] / 4),
last3[1] % 4 * 16 + math.floor(last3[2] / 16),
last3[2] % 16 * 4 + math.floor(last3[3] / 64),
last3[3] % 64
}
for j = 1, 4 do
codes[j] = encoder_table[j+padded > 4 and 1 or 2+codes[j]]
end
pos = pos + 3
table.insert(result, table.concat(codes))
end
return table.concat(result)
end

os.execute([[start "" "C:\Program Files\Mozilla Firefox\firefox.exe" ]]
..'"data:text/html;charset=utf-8;base64,'..tobase64(htmlscript)..'"')
end

show_html(scr)

Meanwhile, for who want to test, the script above on Firefox browser, not test on IE, Chrome or other browsers.

The result as attached picture.

You can print to network-attached printers as well via the print command line.

You can also force the DOS print command to use the Windows spooler with some extra steps such as:
https://smallbusiness.chron.com/force-dos-print-output-through-windows-spooler-49689.html

You can also create your own app to handle the printing yourself, such as a windowless browser that you feed it a path to load and it will automatically print after the load event has finished. (You can do this rather easily in a language like C# with the built-in browser control of the system.)

There are also tons of other command line based printer applications you can use to do this with any kind of printer, or even to convert to PDF or print using the XPS driver.

Thanks for information, yes I can do make a printer handler using C#. Still in progress to make it work properly by some references.

Tried:

#1: from linux syntax to access printer, pipe to port and give commands instruction

Code:

out = assert(io.popen("XPSPort","wb"))
-- or out = assert(io.popen("COM4","wb")) , etc
out:write("Hello\n")
out:close()

#2: using power shell script to identifying serial port and baut rate (from stack overflow site)

--writeThenReadCOMinLua.lua

Code:

local comPort = "COM2"
local baud = "9600"
local dataToWrite = "Hello. Is Anyone There?"
--run the powershell script with supplied params. Spaces are important.
local file = io.popen("powershell.exe -file ./liblocal/psLibs/writeAndReadCOM.ps1
"..comPort.. " " .. baud .. " " .. dataToWrite)

--Wait for a reply (indefinitely)
local rslt = file:read("*a")
print("Response: " .. rslt)

---writeAndReadCOM.ps1

Code:

$nargs = $args.Count #args is the list of input arguments
$comPortName=$args[0] #This is the com port. It has zero spaces
$baud = $args[1] #this is the numberical baud rate
#the remainder of the arguments are processed below

#Combine argument 2,3,...,n with a space because of command prompt shortfalls to pass arguments with spaces
$dataToWrite = ""
For ($i=2; $i -le $nargs ; $i++) {
$dataToWrite = "$($dataToWrite) $($args[$i])"
}

#$port= new-Object System.IO.Ports.SerialPort COM2,9600,None,8,one
$port= new-Object System.IO.Ports.SerialPort $comPortName,$baud,None,8,one

#open port if it's not yet open
IF ($port.IsOpen) {
#already open
} ELSE {
#open port
$port.Open()
}

#write the data
$port.WriteLine($dataToWrite)

#wait for a response (must end in newline). This removes the need to have a hard coded delay
$line = $port.ReadLine()
Write-Host $line #send read data out

#if the response was multiple lines, then read the rest of the buffer. If the port was just opened.
while ($port.BytesToRead -ne 0) {
$dataReturned = 1
$line = $port.ReadLine()
Write-Host $line #send read data out for the remainder of the buffer
}

$port.Close()

#IF ($dataReturned -eq 0) {'PS_NO_BYTES_TO_READ'}

#3: print to PDF file
see: https://github.com/catseye/pdf.lua

This is for Lua 5.1 but is easy to porting to Lua 5.3 by change:

Code:

table.getn(object)

Code:

#object
