How to change username of job in print queue using python & win32print

Asked 2022-Mar-31 at 05:44

I am trying to change the user of a print job in the queue, as I want to create it on a service account but send the job to another users follow-me printing queue. I'm using the win32 module in python. Here is an example of my code:

At the beginning I thought it was a misunderstanding (I was also a bit skeptical about the bug report), mainly because of the following paragraph (which apparently seems to be wrong) from [MS.Docs]: SetJob function (emphasis is mine):

The following members of a JOB_INFO_1, JOB_INFO_2, or JOB_INFO_4 structure are ignored on a call to SetJob: JobId, pPrinterName, pMachineName, pUserName, pDrivername, Size, Submitted, Time, and TotalPages.

But I did some tests and ran into the problem. The problem is as described in the bug: filling JOB_INFO_* string members (which are LPTSTRs) with char* data.

Submitted [GitHub]: mhammond/pywin32 - Fix: win32print.SetJob sending ANSI to UNICODE API (and none of the 2 errors pops up). It was merged to main on 220331.

When testing the fix, I was able to change various properties of an existing job, I was amazed that it didn't have to be valid data (like below), I'm a bit curious to see what would happen when the job would be executed (as now I don't have a connection to a printer):

Change pUserName to str(random.randint(0, 10000)) to make sure it changes on each script run (PrintScreens taken separately and assembled in Paint):

Ways to go further:

Wait for a new PyWin32 version (containing this fix) to be released. This is the recommended approach, but it will also take more time (and it's unclear when it will happen)
Get the sources, either:

from main
from b303 (last stable branch), and apply the (above) patch⁽¹⁾

build the module (.pyd) and copy it in the PyWin32's site-packages directory on your Python installation(s). Faster, but it requires some deeper knowledge, and maintenance might become a nightmare

QUESTION

Why does getSupportedAttributeValues return Paper Types

Asked 2022-Mar-25 at 02:01

The following code snippet should return the Media Trays available to a printer.

However, with some drivers, specifically Ricoh PCL6 Driver for Universal Print and HP Universal Printing PCL 6, in addition to Printer Trays, these drivers also list paper types such as Recycled, Thick, Matte, etc.

From what I can tell, OpenJDK is properly using DC_BINNAMES when calling DeviceCapabilities. OpenJDK doesn't even seem to use DC_MEDIATYPENAMES at all in the source code, so I wouldn't expect e.g. Purple Paper to even be a queryable property, yet it lists when querying trays from the Ricoh driver.

So what's wrong? Are these PCL 6 drivers just bugged? Is DeviceCapabilities at fault? Or does the bug live in OpenJDK?

...

ANSWER

Answered 2022-Mar-25 at 02:01

The drivers are bugged. Workarounds exists, but they are complex.

The short:

Match driver name on Ricoh|HP and PCL6|PCL 6
Filter any trayIds > 1000

The long:

Some drivers such as HP expose the printer trays properly in other areas, for example:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Printers\\PrinterDriverData
- InputSlot
- InputSlotDisplayNames

... however this isn't true for drivers such as Ricoh.

After examining a lot of drivers (HP, Ricoh, Xerox, Konica, etc) I've isolated the issue to the following:

PCL6 drivers
HP or Ricoh as the vendor

In cases with both vendors, the DC_BINS value is always > 1000, which is partially explained in the PCL6 MediaSource specification, quoting:

"... External input trays 1 through 248 are selected by substituting the values 8 through 255 for the enumerated values. Example, 8 = first external input tray, 9 = second external input tray, etc. ..."

Although there's nothing about the 1,000 specifically, and vendors such as Xerox use values over 7000 without the bug. That said, with the problematic vendors, what is observed is that when values are > 1,000 they tend to be actually valid MediaType values (NOT MediaSource values), but incremented by 1,000.

Oddly enough, this is very limited to HP and Ricoh and does not apply to other PCL drivers. For example:

Konica uses trayID of 1000 = LCT, or "Large Capacity Tray", which is valid.
Xerox offers a PCL6 driver, but commonly uses trayIDs higher than 1000, e.g. 7153 = Tray 1, 7154 = Tray 2.
Ricoh is known to use trayID of 1025 in the PCL5 version of its driver, which is a valid tray value of 1025 = Auto Tray Select, but this doesn't seem to be the case for their PCL6 driver, which has the MediaType values mixed in.

So to "fix" this issue, I wrote a series of custom parsing to find out the driver vendor and the tray id.

To locate the trayId from Java:

ANSWER

Answered 2022-Mar-08 at 21:37

A JMP $0604 instruction will change the program counter to the value $0604 and then start executing the instructions starting at address $0604. It will not return back to the instruction after the JMP. To accomplish that you need to change the JMP to a JSR, and make sure the subroutine code at $604 has an RTS instruction to return from the subroutine.

Error: The type or namespace name 'Interface' does not exist in the namespace (are you missing an assembly reference)

Asked 2022-Mar-08 at 12:08

I am developing an application using Xamarin and got stuck into this error. The error has been generated from my .Droid project while building the solution (Clean Solution is successful). The 'Interface' is a folder which is present inside my Portable PCL project. Basically I want to implement an interface (declared inside my Portable project) into my .Droid project. I have already tried to refer that Interface folder with using keyword but it says does not exist. And since the folder is not getting referenced, all the interfaces inside that folder are also not getting referenced.

The below code is of .Droid project file in which interface has to be implemented.

PCL viewer inside QtCreator widget with VTK and QVTKOpenGLStereoWidget

Asked 2022-Feb-27 at 22:21

I need to make a graphical window with a Qt widget that allows to represent inside it a point cloud that I have previously loaded using the PLC library.

Here's what I have so far that doesn't work (I based it on tutorials and this answer).

I'm using:

Ubuntu 20.04
Qt Creator 5.15
VTK 9.1
PCL 1.12

The reason I am using QVTKOpenGLStereoWidget is that as far as I read both QVTKOpenGLWidget and QVTKWidget are no longer available or will be discontinued in future releases.

Of course I posted the question after researching online. However, I could not find the super easy solution available already in PCL.

You just need to use the function:

PIC 16F84 PCLATH Bit3+4 unnecessary for CALL/GOTO?

Asked 2022-Feb-04 at 14:10

I am trying to simulate the PIC16F84 and now need to implement PCL / PCLATH registers.

The PIC16F84 has 1K of Program memory.

The PCL is 8Bit wide, so in this case Bit 0 and 1 of PCLATH is used to switch between the four Pages each having a size of 256B, am I right so far?

Based on this, I do not understand the following:

The Datasheet states for a GOTO:

The upper bits of PC are loaded from PCLATH<4:3>. GOTO is a two- cycle instruction.

But aren't the upper Bits of PCLATH too much? I mean there are only 4 Pages, each 256B, hence only bit 0 and 1 of PCLATH are needed. Or in other words - Bit 3 and 4 of PCLATH are always 0 ? Why would I then need to care about 'PCLATH' when performing a 'CALL' or 'GOTO' ?

...

ANSWER

Answered 2022-Feb-04 at 14:10

The Program Counter is 13 bits. The operand for GOTO is 11 bits, so for the remaining bits you want the two bits of PCLATH starting at 11-sizeof(PCL), ie 3.

Here's a figure to illustrate this:
