I'm using wxMaxima 16.12.0 (Maxima 5.39.0) and when I try to print the output, I get overlapping text.
Here's an example (please, ignore the fact the the command couldn't be correct)
1st image
Sometimes happens also with print and printf (inside a block)
2nd image
printf(true, "Link ~d~%", i),
print("+------------------------------------------------+"),
3rd image
But outside a block
4th image
This makes all the output completely unreadable, and my program heavy relies on it. I think that in the 3rd image, the problem is that there is the 2 at the denominator is causing the "shrinking" of the output.
How can I solve it? Is it my problem or Maxima's?
OS: Mint 18 sarah
Kernel: x86_64 Linux 4.4.0-57-generic
DE: Cinnamon 3.0.7
P.S. I also noticed that sometimes, re-running previous commands could make "readable" the following, but that always happens random
EDIT1: I noticed that the last packages that I installed are
libwxbase3.0-dev
libwxgtk3.0-dev
libwxgtk3.0-0v5
libwxbase3.0-0v5
Could it be that there's some kind of conflict?
EDIT2: if I cut the command, the output is "reorganized" in a decent way

As BillThePlatypus requested, I'll answer so that everyone will have a quick solution.
In my case, just changing the font solved the problem (i.e. no more overlapping prints), so give it a try.

Retro printer day: I have an old IbmPro compatible dot matrix printer connected by a USB parallel adapter to my Ubuntu 20.04 system. It works great! One major trick in setting it up: set the URI to /dev/usb/lp0 and make sure the lp user is in the right group to write to that dev. That took me a while to figure out. I use the IBMPro generic printer driver and it's great. Other critical hints: 9600 baud, 8 bits, no stop bit, hardware flow control.
The one remaining problem: the print area is offset about 0.5" to the left. I'm sure I know what's going on: the tractor feed area is about 0.5" and so I need to somehow indicate, don't count the tractor feed area within the page margin. In other words, the full page width is about 9.5" but only print 8.5" of that and offset it 0.5" to the right.
I've tried editing the PPD file including changing the values in HWMargins and ParamCustomPageSize WidthOffset. None of this seems to have any impact. I've read a bunch of documentation about PPD files and it's just not clear what to do. I guess I could set up a custom paper size of 9.5" width but I would prefer to just have all my documents be the same and print correctly by offsetting everything as it's generating printer output.
There must be a simple setting for this.
Edit: tried a lot more things including:
Go to Printer Properties and go to Job Options. There's a left margin setting. I set it to 36 points, or half an inch, and that moved printing over. Adjust as desired. But that didn't work. I also tried to make this change in the PPD:
ImageableArea Letter/US Letter: "18 36 612 756"
and that didn't work.
It is fixed. The order of parameters for the gs line in the PPD must be just right and it's not obvious how to get it working. After much trial and error, this line works:
*FoomaticRIPCommandLine: "gs -q -dBATCH -dPARANOIDSAFER -dQUIET -dNOPAUSE &&
-dNOMEDIAATTRS -dNOINTERPOLATE -sDEVICE=ibmpro%A%Z &&
-sOutputFile=- &&
-c "<</PageOffset [36 0]>> setpagedevice" -f -"
It must be in exactly that order. Adjust the offset values (36 for the horizontal offset, 0 for vertical, in this case) as needed. This really should have been easier, given that it's going to be quite normal to adjust offsets on any dot matrix printer. I hope this question is useful for anyone else in this situation. Yes do pay attention to the HTML escapes used in the line above, they are correct. I tried before using ' and that didn't work. It must be ".
This was really a lot of effort to figure out although would probably be obvoius to someone experienced in PPD files.
I'm trying to batch scale a load of xpm images to double pixel size. I can do this using ImageMagick like this:
convert infile.xpm -sample 200% outfile.xpm
However, the symbolic colour names are lost.
In the original input, the colour entries are as follows:
". c #007EBF s active_hilight_1",
"+ c #0A5E89 s active_color_1",
"# c #143D52 s active_shadow_1",
In the up-scaled version:
" c #143D52",
". c #0A5E89",
"X c #007EBF",
The colour names changed, which is fine, but as you can see the s <symbolic-name> suffixes are stripped.
Does anyone know a quick way to do this using ImageMagick or a similar (open-source) utility?
Thanks
EDIT: Seems ImageMagick can't due this due to a bug, but does anyone know any other tool which may be able to do this?
mogrify -sample 200% *.xpm
^ This works as long as you have a new (post 2019-09-02) version of ImageMagick with the xpm output bug fixed, as described here:
https://github.com/ImageMagick/ImageMagick/issues/1684
Today's master branch, for example, passes symbolic colour names through properly.
I created a label program using C# and the Zebra SDK. It works great except when a user desides that they printed the wrong labels and they power off the printer. When the printer comes back on, it goes through a quick calibration (I believe that's what it's doing) and then the light changes to a solid green. When they try to print again, one label prints correctly and then two blank labels "print" and the status light changes to a blinking red light. In order to get the printer back into a working condition, it needs to be recalibrated and I use the ZPL command ~JC.
We were using ZebraDesigner software to print labels and the printer never had issues with being powered off, back on and then printing as normal. I captured the data that is printed from that software and added the ZPL to my code but it doesn't help the printer recover when the printer is powered off. I don't know if the ZebraDesigner software is actually sending multiple sets of commands and I'm only capturing the last set or not.
It was suggested to me on another forum that the printer might still have some of the old ZPL data from the last print job and it would need to be cleared. The last thing I tried was adding the soft reset command ~JR to my code but it didn't help. I also tried to clear anything in the buffer using ~JA with no different results.
Here is is my original ZPL code and it does not include the ZPL that I captured from ZebraDesigner becuase it didn't help. I've gone through the ZPL guide multiple times and I'm just not having any luck figuring out what I'm missing that isn't allowing the printer to recover without being calibrated.

After more testing, I found the command. It's ^MNY
I found it by running through the file generated by Configure Printer Settings in Zebra Setup Utilities. I ran that ZPL with my ZPL and it fixed the issue. I then narrowed down the code until I found the command that allowed the printer to contiue to function after being turned off. I did see this command in the ZPL guide and thought I tried it but maybe I messed something up.
I have an SQL assignment for UNI due in a couple days. I played around with SQL settings using the 'set' command and I have messed up the output of queries (see screenshots, link below).
The output seems to be writing to a fixed line length, instead of using the full length of the terminal console. I am using tmux in iterm v3.2 but also have the same issue on the native MAC OSX terminal.
Is there a way to reset these settings to default? Or somehow make it work for me? I just want the lines to be displayed to the right side of the screen, until it needs to be wrapped.
Let me know if this is a dupe.
Got it!
This is controlled by the pagesize environment variable.
For the screenshot I had pagesize set to 14. Which means print 14 lines, with a blank line for the 14th line, before printing the rest of the output.
I changed the pagesize value to 200, this should be enough for what I need.
set pagesize n

I need to use maxima software to deal with data. I try to read data from a text file constructed as
1 2 3
11 22 33
ect.
Following comands allow for loading data sufficiently.
load(numericalio);
read_matrix("path to the file");
The problem arises when I apply them to a more realistic (larger) data set. In this case the message appears Expression longer than allowed by the configuration setting.
How to overcome this problem? I cannot see any option in configuration menu. I would be grateful for advice.
I ran into the same error message today, at it seems to be related to the size of the output that wxMaxima receives from the Maxima executable.
If you wish to display the output regardless, you can change it in the configuration here:
Edit>Configure>Worksheet>Show long expressions
Note that showing a massive expression or amount of data may dramatically slow the program down, so consider hiding the output (use a $ instead of a ; at the end of your lines) if you don't need to visualize the data.
