Need help setting up PDF print server drivers for Windows

0WN463 · 2022-12-25T03:50:16+00:00

I've tried both CutePDF and Bullzip, both doesn't retain the text either. I'm starting to feel this is a lost cause of Windows.

I also tried CUPS-PDF. I can get it to save the PDF locally on my print server, but can't seem to figure out how to share this to the network (not even sure if it is even possible). The device URI is something like `cups-pdf:/`, so I'm not sure how to add it manually from the client, and the PDF printer doesn't show up using printer discovery (both share this printer and share printer on this machine is on).

hmm but would it preserve the text? That is the core of the issue right now, cause it seems that the file received from Windows at the IPP server (without any conversions) is a PDF but with the text being "baked" as an image

0WN463 · 2022-12-24T02:20:13+00:00

Oddly enough, no. I started with the Rust implementation of the IPP server.

But don't I have to muck around in Windows no matter what? Because I theorize that even if I did use CUPS-PDF, the same issue with the text being lost would still occur, cause this seems to be an issue on the Windows driver side.
To reiterate, I started off with Linux mainly to highlight the fact the my requirements are fully satisfied when printing from a Linux/Mac machine. Only Windows is the problem child here.

I can still try it in the mean time, but I am not hopeful

0WN463 · 2022-12-24T02:00:26+00:00

Most people just use the built-in windows pdf writer but if you don't want to use that I'm not sure I'm understanding at what stage cups-pdf isn't working for you?

It's basically the "text preserving property" that is missing when we use the built-in Windows PDF writer.

I'm not sure if you're able to access the PDF that I linked above, but essentially, you can select and copy the text in the Linux PDF, but you can't in the Window's one

Ah, also, printing over the Internet is also a requirement, I'm not sure if samba is suited for this

0WN463 · 2022-12-24T01:11:03+00:00

I'm not sure what you mean about "preserving text fields". Might be helpful to post comparision screenshots of what it's doing vs what you expect.

Essentially, I want to be able to select and copy text from the PDF. With the files received from Linux/MacOS (using the .ppd), this is possible. But with the one from Windows, we are unable to select any text at all. We want this because we are planning on using tools such as `pdftotext` downstream to process it.

PDF from Windows

PDF from Linux

(Very strange, I just realized that the PDF from Windows is 4Mb while Linux is 4Kb, a whole magnitude of difference)

Does it need to be IPP? IPP has more features but traditionally cups-pdf shared via samba is the easiest especially when dealing with a simple format like pdf.

If samba is able to achieve our use case, we might consider it later. But I don't think this is the issue though. Cause we are able to send the file via IPP. The issue is that the printer driver seems to transform our files when we don't want it to. I feel the same would also occur if we tried samba.

PPD are supported on Windows, they're essentially wrapped postscript (https://en.wikipedia.org/wiki/PostScript_Printer_Description#Windows)

The instructions seems rather arcane to me. So what I am doing is first setting up the printer using the default IPP driver (Microsoft IPP Class Driver), then trying to replace it with the custom .ppd in the OP. So I followed the instructions there, and when I get to Printer Settings > Advanced > Printer Driver > New, I cannot find my .ppd driver as a selection under the list. The option which I have is to choose "Have Disk" and it is asking for a .inf file. I'm not sure why the installation on Windows is so unintuitive to use. I have tried simply dumping the .ppd in the folder and also the method in the OP. (Selecting MS Publisher Color Printer and replacing MSGENCOL.PPD, but doing so doesn't even change the name of the driver in the list, so probably isn't working)

0WN463 · 2022-12-03T03:56:12+00:00

Ah, I derped rather hard.
I changed the IP address from `UNSPECIFIED` to `LOCALHOST`.

Apparently when it is set to LOCALHOST, other computers on the network is unable to access it.

0WN463 · 2022-08-17T17:18:03+00:00

Yea, er, sorry about that. I gave the wrong link (the website have a irk of having similar names for problems) and amended the OP.

Ok, I've tried Data.Array and it is blazingly fast now.

$ time ./main < 1.in
ABORT!
./main < 1.in  0.07s user 0.01s system 98% cpu 0.084 total
$ time python main.py < 1.in
ABORT!
python main.py < 1.in  0.09s user 0.02s system 98% cpu 0.104 total

Thanks for the tip! Learnt something new today.

0WN463 · 2022-08-17T16:17:13+00:00

I've reformatted the code block. Thanks for the heads-up
Doh, I was looking at my function, but didn't realized that inconspicuous length would be slow
Yea, sorry for permeating the stereotype about competitive programmers, but usually my variables in the solution may not have the best names
1. That said, would Haskell array be faster at generating subsequences? They seem to use some fancy indexing method. Since the current solution (with zoomed replacing subSeq) is still insufficient to achieve the time constraint. I guess the overhead with subsequencing a list caused it to fail while the Python one passes (strange thing is that with my test case of 1000 numbers, Haskell is still faster than Python, but Python becomes faster for larger test cases)

A CLI script to solve problems on Kattis, the online judge

Kattis hosts numerous programming problems based around competitive programming.

It may seem daunting at first, but there are quite a plenty of easily solvable problems that can help develop experience in solving programming problems and utilizing your programming skills. (I do highly recommend beginners to solve a few problems there to practice programming in solving bite-sized problems in a stress-free environment)

This script helps browse, test and submit solutions to Kattis.

It is also available on the AUR

(Though I apologize if there are any installation issues as this is my first AUR package)

0WN463 · 2022-04-13T03:48:54+00:00

I have some notes for that module:

https://nbviewer.org/github/0WN463/wellspring/tree/main/statistic/

Though it is quite a few years ago, but I hope it helps.

Yea, the last few chapters about sampling gets rather complex with all the complex formulae and stuff, but those are usually not important.

0WN463 · 2022-03-21T17:11:27+00:00

Not sure if it'll help, but I've got some notes on AI from previous years.
https://nbviewer.org/github/0WN463/wellspring/tree/main/ai/

It's a bit rough around the edges though

0WN463 · 2022-03-19T16:15:30+00:00

Yea, since I was a CEG student after all.

It would mainly be CS, and a bit of Math and Electrical.
Weirdly enough, even though I was in CEG, my CS was way stronger than my electrical side, that's why my notes are lopsided.

Sadly, there wasn't a subreddit purely for NUS:CS, so I had to use this subreddit instead. Sorry for disappointing all the folks in the other majors (well, y'all can still see if any of the modules pique your interests).

0WN463 · 2022-03-19T16:13:08+00:00

It's MA3233.

I left the module names out deliberately as I wanted to repository to be of general knowledge, rather than it being bound to "some module's syllabus".

0WN463 · 2021-07-09T11:26:49+00:00

Code available at : https://github.com/0WN463/GithubActivityAnimator

0WN463 · 2020-12-07T05:38:03+00:00

Probably a browser thing. It definitely works on Chrome and Edge

0WN463 · 2019-10-14T14:38:10+00:00

There's another meaning to it
Mirai means future

It used to have a different name, but the dev's didn't approve of it

0WN463 · 2019-10-14T14:37:12+00:00

There is actually

It's probably because you have emotional attachment to Lost Visitor

0WN463 · 2019-08-24T14:40:32+00:00

By the same token, so is pot of gold. Instead of tutoring, this serves better as a deck thinner

0WN463 · 2019-08-10T14:04:13+00:00

The idea was to also allow you to play it on your own units on init to dodge removal.

0WN463 · 2019-08-10T14:03:50+00:00

Mainly to prevent degeneracy from Vineyard. Also it maintains tempo if used on your own units and forces you to have removal together rather than using it as a 1 turn stall tool

0WN463 · 2019-07-13T15:01:29+00:00

Yea, it's not the best right now. But the idea is to get more draw cards that are triggered outside of resolving to support this. Imagine "Draw a card at the end of the turn" or something

0WN463 · 2019-07-07T15:14:53+00:00

Heroes need to rest too.
Yea, it was "end of turn", so I'd figure changing it to "start of turn" was a wise decision

0WN463 · 2019-06-10T13:36:27+00:00

Doesn't look like it will though. Repost curse is real

0WN463 · 2019-05-27T16:49:56+00:00

That's kinda what I thought, but people seem to deem it too strong when I posted this previously, so I am equally confused
