问题 Basicaly what i want to do is retrieve hp's Printer Model from network printer via SNMP in c#. Searching SO didn't yield anything usefull. Where do i start? 回答1: You'll need to either write an SNMP manager or use an existing library (there are plenty out there; this is the one I use, and here's another.) From there you'll poll the apropriate OID to get your printer model (you'll want to see the printer's MIB for that value). 回答2: Download one snmp library and make OID as 1.3.6.1.4.1.11.2.3.9

问题 I have client which has a problem with printing from JAVA applications, using old Brother printers. The exception he gets is "Printer is not accepting jobs". Other applications (not java applications) manage to print using these printers. He switched to a new printer (also Brother), without changing the driver and then it worked. The idea is that he cannot change all the printers, also he does not want to reinstall all of them, as he has a network of hundreds of computers and printers. I have

问题 I have got a .txt file that contains a lot of lines. I would like my program to ask me what line I would like to print and then print it into the python shell. The .txt file is called packages.txt. 回答1: If you don't want to read in the entire file upfront, you could simply iterate until you find the line number: with open('packages.txt') as f: for i, line in enumerate(f, 1): if i == num: break print line Or you could use itertools.islice() to slice out the desired line (this is slightly hacky

问题 I am writing a C# program to change the orientation of print job. Here is how I am doing it • Open Printer using OpenPrinter() • Get the job details with JOB_INFO_2 structure using GetJob() • Change the orientation in JOB_INFO_2 structure • Set the JOB_INFO_2 structure using SetJob() But when I call SetJob() method it always fails with the return code 122.

问题 I am working on an application that will sport a web-based point of sale interface. The point of sale PC (I am not sure as of now whether it will run on Linux or Windows) must have a fiscal printer attached to it, but like any web app, it is the server which processes all stuff. Both server and PoS machines are on the same LAN. I must send the sale data in real time, and via the fiscal printer which uses the serial port, so printing a PDF or even a web page is not an option. I've been told I

问题 I'm printing data in Perl6 with Data::Printer which is a spectacular package, but I am trying to alter parameters and I am not able to.
