I have setup a pdf etc. to print from my MacOS application, but I cannot figure out how to set the number of print copies in swift, everything else is there but I can't find the number of copies.

I have a relatively complex Perl program that manages various pages and resources for my sites. Somewhere along the line I messed up something in a library of several thousand lines that provides essential services to most of the different scripts for the system so that scripts within my codebase that output PDF or PNG files no longer can output those files validly. If I rewrite the scripts that do the output to avoid using that library, they work, but I'd like to figure out what I broke within my library that is causing it to hurt binary output.
For example, in one snippet of code, I open a PDF file (or any sort of file -- it detects the mime type automatically) and then print it directly:
#Figure out MIME type.
use File::MimeInfo::Magic;
$mimeType = mimetype($filename);
my $fileData;
open (resource, $filename);
foreach my $self (<resource>) { $fileData .= $self; }
close (resource);
print "Content-type: " . $mimeType . "\n\n";
print $fileData;
exit;
This worked great, but at some point while editing the suspect library I mentioned, I did something that broke it and I'm stumped as to what I did. I had been playing with different utf8 encoding functions, but as far as I can tell, I removed all of my experimental code and the problem remains. Merely loading that library, without calling any of its functions, breaks the script's ability to output the file.
The output is actually being corrupted visibly, if I open it in a text editor. If I compare the source file that is opened by the code given above and the output, the source file and the output file have many differences despite there being no processing in the code above before output (those links are to a sample PDF that was run through the broken code).
I've tried retracing my steps for days and cannot find what is wrong in the problematic library -- I hadn't used this function in awhile and I wrote a lot of new code since I last tested it, so it is hard to know precisely where the problem is. My hope is someone may be able to look at the corrupted output file in comparison to the source file and at least point me in the direction of what I should be looking for that could cause such a result. I feel like I'm looking for a needle in the haystack.
We are using a new printer unit but it didn't follow the inputted number of copies. We tried to print it on our old printer and it was able to follow the number of copies. The number of copies worked in DocuCentre S2320 printer but not in HP LaserJet Pro P1102.
This is the code used for calling the report.The numCopy variable is used for the number of copies.
RUN _printrb(rptDir,"Summary Report","","O","","","D","?","","",numCopy,vPage[1],vPage[2],no,"",yes,yes,no,"").
I would like to use some special characters in a MATLAB figure. How can my program ensure the fonts are available before using them?
listfonts() is not reliable. It claims "Zapf Dingbats" is available on my machine, but it is not (and text() renders using a default font instead). listfonts() always includes the standard PostScript fonts. I suppose that's because they are always available for PostScript output, but I'm interested in displayed figures. Likewise uisetfont() and MATLAB -> Preferences -> Fonts -> Custom list "Zapf Dingbats", but render the sample using a default font.
Just looking for the font file doesn't work, either. For example, "Webdings" works fine on my main machine. However, on a second machine, "Webdings" is installed (there's a file /Library/Fonts/Webdings.ttf, and Word can use it), but MATLAB substitutes a default font.
I thought of one test: Create a small figure with one marker symbol, use print() to write it to a .png file, read in the file as data, compute a hash, and compare that hash with a stored value. Is there a less clumsy method?
I found Unicode equivalents for most of the symbols I need, that work for both of my test machines. However, they too apparently depend on my having the right fonts installed. For example, there are many Unicode versions of a square. Hex codes 2588, 25a0, and 25fc work here, but 25fe, 2b1b, and 2bc0 are rendered as blank. Is there a way to tell whether these characters are available?
I'm running R2017b under macOS version 10.13.5, and "set | grep LANG" displays "LANG=en_US.UTF-8".
I have an arduino that spits out a single line of GPS data down the serial line every half second, which I know works because I can look at the serial monitor in the arduino IDE and every half second, a new single line of data appears.
I'm now in the process of writing a Mac program using Swift that puts each coordinate on a map as it comes in through the serial port, and am using the ORSSerialPort library to connect to the arduino and receive its data. This works fine and I had a basic version working earlier, however I noticed that there were gaps in the GPS data (they were appearing in small groups on the map, with a noticeable space in between when it should be a constant line of them).
Before I had the map I had a text field that would have each GPS data line added to it as it came in, which produced the exact same output as the arduino IDE serial monitor, so I thought everything was working fine.
To try and fix the problem with the map I removed the map code and simply print()ed out each line into the XCode IDE as it came in through the serial port. To my surprise there were random line breaks in the data and I don't understand why. I feel that this may be causing the problems I am having (with splitting the string at every comma so I can extract the individual values) so would like to know why it comes out as a single line in the arduino IDE and the text field, but not in the XCode IDE and presumably whenever else I am working with the string.
EDIT: I prefixed the print to XCode IDE and the output to the text field with five plusses and suffixed them with five dashes, then set the serial port to close after sending a single report (what should be a single line of data). The output I got to both things ended up being three lines, each prefixed and suffixed with the plusses and dashes. See the photo below, which shows what should be a single line:
Why are my single lines of data coming through over multiple lines and behaving like individual variables (as in getting the last character of the line returns the last character of the first line of the three, not a semi colon)?
The issue isn't likely that there are extra newlines being inserted. Rather, ORSSerialPort (like the underlying POSIX API it uses) simply reports data to its delegate as it comes in. It has no way of knowing that for your particular use case you only want complete lines.
You need to buffer the incoming data and only process it when you've received a complete "line"/packet. ORSSerialPort includes an API, ORSSerialPacketDescriptor that makes this easier. There is further documentation for that API here: https://github.com/armadsen/ORSSerialPort/wiki/Packet-Parsing-API
Do note that this API doesn't (yet) support the use of a end delimiter only. You need to validate the entire packet beginning to end, as the parsing routine is "lazy". That is, it tries to find the smallest match possible starting from the end of the packet.
Long story short, all I'm really attempting to do is print my reports on half sheets. I had Kinko's chop a pack of printer paper in half and my laser printer is perfectly happy to suck them in and print the reports properly, if the paper size of the Excel report is set to exactly 8.5" x 5.64".
That can be done easily in Excel, but it's the one and only adjustment, in my project, I wasn't able to automate with Perl using Spreadsheet::WriteExcel. The CPAN documentation states that you can pick from some of the default sizes normally available with Excel, but doesn't provide an option to specify your own paper size.
Even if you establish the custom size you need in Excel beforehand, making it available in future spreadsheets, as one of your selectable paper sizes, there doesn't seem to be an index, using set_paper($index), that would specify that newly established custom size.
Thank you in advance!

Since VBScript can do many of these things natively, maybe you could try embedding the necessary VBScript into your main Perl script using Inline:WSC.
You could determine the needed VBScript by recording an Excel macro of you setting the print size. Then embed that code into your main Perl script.

As far as I know there isn't an option in Excel to set a custom paper size. This is usually set in the printer (correct me if I am wrong).
Excel can store printer information along with the workbook data so there may be a workaround.
Can you send me a single sheet workbook with data in cell A1 only and a copy with the custom page set and I'll take a look to see if it is possible.
P.S. The available option B5 (index 13) in landscape mode is fairly close: 8.27" x5.83". Or the undocumented "Organiser L" (index 129) which should be half Letter size: 8.5" x 5.5".
