I send the CMD8 command to find out what version my Sd card has, but the answer is split between CMD and D0 so the dirver goes into timeout. I don't understand what it could be.

I have a thermal printer "MPT-II" from an unknown Chinese brand, that has both USB and Bluetooth. I can successfully print text using:
Loyverse app on Android
JavaScript
Raw HEX or decimal
However, only using the Loyverse app am I able to input special characters, and by special characters I mean the Danish characters æøå/ÆØÅ.
If I open up any BLE tool on Windows (Bluetooth LE Lab for example), I can select the correct characteristic and send something like 104 101 108 108 111 13 10 which would print "hello" on the printer. I've read a bit about the ESC R and ESC t commands, but how exactly do I set those modes? I've tried prepending it to each command, such as 27 82 1 104 101 108 108 111 13 10 where the 27 82 1 corresponds to ESC R 4 and the 4 corresponds to Denmark I.
According to the printer's manual, it states the following:
GB18030 character set, ASCII characters, user defined characters, bar codes CODE39, EAN13, EAN8, CODABAR, CODE93, ITF, bitmaps.
According to that list, the Danish character set is not supported. I'm not sure how the Loyverse app is doing it correctly, but the text is the same using raw commands and Loyverse, so I don't think Loyverse is converting to a bitmap and sending that data.
So my real question is: How do I send the correct character set for my printer? Maybe the character set is already correct, but the ASCII character for æøå/ÆØÅ are wrong?
EDIT: I have confirmed that something works with the ESC XXXX commands. If I do 27 97 2 followed by my "hello" sequence, the text is printed to the right (right aligned). So that definitely works.. I have tried probably all character sets thus far using ESC R and ESC t but none of them work :(
EDIT 2: I have now tested every single combination of ESC R and ESC t. I went through the entire list printing some Chinese characters, and every single line of 150+ I tried all returned the same Chinese character. So ESC R or ESC t is definitely not the command I should be using to change the charset.
I am trying to print in page mode on the Epson TM-U295 slip printer:
ESC "#" ; Initialize
ESC "q" ; Release
ESC "K" 31 ; Reverse feed 0.82in
ESC "L" ; Select page mode
ESC "T" 3 ; Select top-to-bottom direction
"7/26/2019"
FF ; Print and return to standard mode
ESC "F" 1 ; Set reverse eject
FF ; Eject slip
ESC "q" ; Release
The problem is that after printing the date, the printer just keeps feeding the paper. I have to turn it off to make it stop.
Is there a mistake in my command stream?
You just set the page mode and the print direction, and have not set the page mode print area.
In that case, the default for the area of the TM-U295 printer is the maximum value from 0x0 to 210x480.
Even if only one line of date is written, if printing is started, paper feeding is performed to print all 480 vertical areas.
If you want to feed by the number of lines to print, after setting the page mode, you need to set the page mode print area of only the necessary minimum size before sending the print string.
The corresponding page is in Japanese.
ESC W xL xH yL yH dxL dxH dyL dyH
I need to be able to print Hebrew characters on my Epson TM-T20ii. I am trying to get my printer to switch to character code page 36(PC862) using
ESC t36
for some reason the printer is switching to code page 3 and then printing the number 6.
Is there a way to let the printer know that the 6 is part of my command?
If you know of a different workaround please comment below.
Thanks
You are making a mistake, you aren't meant to replace n with an actual number.
The proper syntax in your case would be ←t$
Explanation: the manual says "ESC t n", n referring to the page sheet, however you don't replace n with a number rather with the ASCII character n, so in your example 36 = $ because $ is the 36th character on the ASCII table.
I have a new label printer (Brother QL 570) wich supports endless paper. My thought was, that I will be able to save paper by printing just as much paper as I need - wrong!
The printer comes with paper sizes of 63mm x 100mm and 63mm x 29mm (and some others) but I need 63mm x 'felxible lenght' or something like 63mm x 40mm.
How can I change that? I will print from OpenOffice.
Thanks!
(Driver is CUPS, using Mint 17.1)
The CUPS drivers that come with the printer include a utility for adding custom paper sizes.
Open a terminal and type:
brpapertoollpr_ql570
And you will see the usage examples for adding and removing custom sizes:
===========================
LPRng Paper Size Tool (v 0.1) Copyright by 2005
Usage: brpapertoollpr_xxxx -P QL-xxxx Printer Name [-n add a Lable Format Name (<=32 bytes) -w Media Width(unit:mm) -h Media Height(unit:mm)]/[-d delete Lable Format Name]
For example:
1. Add a new Label Format with "New Label Format" name and 29mm width and 70mm length:
"brpapertoollpr_ql570 -P QL-570 -n New\ Label\ Format -w 29 -h 70" [enter]
2. Remove the Label Format with "New Label Format" name:
"brpapertoollpr_ql570 -P QL-570 -d New\ Label\ Format" [enter]
===========================
As an example, I did
brpapertoollpr_ql570 -P QL-570 -n long_label -w 62 -h 200
to set up a custom paper size called "long_label" which prints on 62mm continuous roll, a 200mm long label
I have to print Java code that some times reaches 300 columns (characters per line) in A3 paper and whatever editor I use (e.g. textmate) wraps the lines in order to fit in A4 paper.
Any suggestions?
cheers,
Asterios
Your editor undoubtably has either a Page Setup dialog or a Preferences dialogue as part of the Print Dialogue which will allow you to set the Paper Size to use for printing.
Even Notepad supports this
I finally made it to print using enscript. Here is the command I used to print Java code into PDF (and the used the pdf to print).
enscript -r -Ejava -M A3 -C -f "Courier8" input.java -o - | ps2pdf - output.pdf
where:
-r prints in landscape mode
-C prints the line numbers
-f changes the font and size
-M sets the output media to A3 (default is A4)
-Ejava adds syntax highlighting (you can also use --color if you need
colors in syntax highlighting but
they are not nicely printed in
greyscale)
It seems unlikely that every editor tries to format for A4. Which other editors have you tried? Does textmate not have a page size option? (Hmm... seems not)
Try a different editor that does let you set page size. Word, even.
