One thing you could do is grey out QU's media preset window when QU finds an HP Designjet printer driver, it is really the main risk for CM issues.

I did look into that about a year ago as I thought that might be a better option too.  I decided not to remove that feature for DJ drivers because I found that at least the media type settings worked OK when the driver is first installed.  The custom media size problem is an issue from the start but the problems with media type collisions in the driver don't seem to surface until some number of user media presets are created (and saved) in the driver.  So I didn't want to disable the feature for all and at least at the time, I thought I had a reliable way to determine if the media type bug existed at any given time.  I do detect collisions or missing indices in the media type table, so I thought that should eliminate any CM issues where the wrong paper type is chosen; with your latest report, however, I may have to take another look.  The steps that I took to "work around" the driver bugs may not be as complete as I thought.  When I find a duplicate media type index, QU should report "Select in driver" for example.  And when there is NO index found in the table for the paper you chose in the driver, it should list "UNDEFINED" along with the index number.  That seemed to prevent any problems where QU could indicate one media type but the driver have selected a different one.  Worst case, QU should show "UNDEFINED" or "Select in Driver" and you'd know you would have to open the driver.  But I'll try to take another look: it wouldn't surprise me if there are other bugs that I wasn't aware of (and don't detect yet).

Mark, I will manage as it is.  Though I am still curious whether the Z9+ driver might cope better in practice. It is the machine to upgrade to one day. Hardware wise I do not know a better one for me than the Z3200. Software wise HP can improve a lot, not just drivers, its websites as well.

My money would be on the HPZ9 printers having all the same driver bugs as the Z3 series.  A year ago I outlined a number of serious bugs in the Z series drivers and included proof via specific examples that showed how the HP drivers were not following the Windows driver specs... along with the simple code fix that was needed to make them comply with the specs.  I sent this info to someone I had worked with in the past who I knew worked on the Z series drivers for HP; turns out he no longer works for HP but was able to give me some information.

From that interaction, my understanding is that every HP Z driver includes the code for every Designjet printer back to the first one released.  They don't write new drivers: they simply take the old one from a prior model and add in new features.  Because of this, the Z series drivers are now over a million lines of code and no one wants to touch the baseline code that has been there for years: I was told no one dares touch it and it is considered "cryptic and obscure".  Given this, I would suspect that the bugs that plague the underlying Windows framework (API) support will just propogate from one HP DJ printer to the next and will never get fixed.

I've expressed my concern that I'm able to support features on every other printer that cannot be supported (or suppoerted fully) on HP Z series printers because their drivers don't comply with Windows standards.  But I'm convinced they've built such a rats nest of code that they now do not have the resources to fix it: if you can get a print to the printer... leave it alone!

Mike

Thank you Mike,

I saw the Designjet Z5200 name flashing by when I installed the Z3200 PCL3 driver on Windows 10 last week. Which intrigued me. One thing you could do is grey out QU's media preset window when QU finds an HP Designjet printer driver, it is really the main risk for CM issues. Sizes and portrait/landscape settings can also result in problems but the HP Print Preview stop in the workflow shows it when a print page meant landscape lands as portrait on a roll, most common issue then. Can still happen though when the roll is not 1118mm or 914mm wide but one mm less, so I have my custom media size settings at 1mm less.

I can manage but last week I tried a 2017 version of QU to get rid of the maze routes I am used to now. Too many new features and a better general GUI in the QU 2020 versions though. What helps is making the default settings of the HP driver to one that is most used in practice and having it set at 600PPI requested input quality. The last takes more printing time if it was not intended but the quality does not suffer then. The other way around it can lower quality on the best papers. Next to that I have extra Printing Shortcuts in the HP driver for more usual print jobs.

Is Qimage One coping better with HP Designjet drivers?

I live in Belgium and use the A3 format which is 11.7 x 16.5 inches

It would help if you mentioned the printer used, size of the printer (max sheet size), whether the sheet can be fed manually instead of automatic from a tray and the feeding is landscape or portrait style.

If the HP Designjet Z9+ has the same incompatibility with QU's integration of the HP printer driver as the HP Z3200 has then I fear you have more issues with the Media Preset setting in the driver not sticking instead of issues with the color management choices. With the HP Designjet Z3200-PS my last step in setting up a print job is opening the real driver settings again and checking the Media Preset again, the portrait/landscape mode and the print quality settings (300/600PPI + gloss enhancer modes: off/economy/whole page) and then an OK.  If QU's printer menu window then shows another media preset I am not worried as I know the real driver settings are OK.  This way the other QU's printer driver menu windows (size, portrait/landscape, 300/600PPI) will show the settings as done in the real printer driver menu. The other way around, setting everything from QU's virtual printer driver menu can give problems on Media Preset and portrait/landscape setting in the real driver and the print quality setting dropping to the default. This applies as well on jobs taken from the log file.

If the HP Z9+ + driver behaves the same .......... I have no experience with that printer and driver.  I am very interested to know whether that is the case or not though.

Priority: Low

2020.110 supports up to 12 processing threads to speed up thumbnail, raw, and print processing speeds on modern high end systems.

Mike

Quite a coincidence as I bought parts for a system like that just before this announcement. Thank you. Will take a week probably before I can test it but the old system with 4 cores became really old so it will be a big step forward anyway.

Hello Mike,

This must be quite a step in the color management, LCMS can handle it but nevertheless. Any advice on rendering intent to choose as we will still be faced with RGB device profiling for the OEM printer drivers?  I guess for CMYK color fidelity absolute colormetric. Most inkjet photo printers have a gamut bigger than the usual CMYK spaces.  BPC ?   Is this a prelude on more to come like Lab images support?

What Fred said.  Wink  I'll only add that in your case, you should probably try Crop Marks (which extend outward from each corner) and Mark Corners (which bracket each corner against each print).  Not sure which you'd prefer.

Regards,
Mike

I use these quite frequently. The only trouble is that when you make your first cut, you cut of the guides for the next (two) cuts. I don't think there is any way around this without having the guides on the cut print. I manage it by extending the mark in towards the print by a mm or two with a scalpel. So when I cut off the first edge, I can then see where to cut the next two from.
Jules

I suggest to read my other comment in this thread.

Ernst, op de lei getypt.

Great ... will have a look later.

Thanks for the reply's and photos.

Add 0.5mm white borders + corner marks and cut just within the marks. That way you waste less paper and keep  marks on the printed image up to the last cut. Do not nest the images too close, cut becomes better with say at least a 2mm strip cut off.
Cutting marks that extend from the corner as used in the graphic industry have more sense when stacks of sheets are cut together on a guillotine cutter.

Ernst, op de lei getypt.

Have to upgrade yet but it sounds wonderful.  I try to keep my files at the same spot over time, the more the customer files, but sometimes you have to reorganize them for good reasons. And I usually know where to find the files for a reprint but this should make it easier. Thank you Mike.

Hi there iīm new with QU and Coming from Germany. I use a Epson SC-P600

My question is:

I get some ICC-Profiles for my likely used paper and the settings for make those ICC is set to 1440 res. Now in all videos is said to sett Quality to the highest res, so is more than this 1440.

All other sources says to get a fit ICC is to use all settings like they where set to make the colorpattern is used to calc the ICC for the printer, the paper and the ink. Do not so , they say, is probably to lower the quality of print use a different setting. Allso i think some time i waste time to use a res i dinīt need for small printīs.

What do you think about my thoughtīs ?

I hope you can understand what iīm thinking about and i dont make whorst mistakes in writing. Itīs ~ more than 35 years since i learned last time English. Speaking mot but writing not.

Have a nice day.
schorschi

Color targets are often just 300 PPI or 360 PPI. While the profile creator documents say to use the same settings in target printing (but CM off) as will be used in normal printing, the OEM printer profiles exist in only one flavor these days. If print quality suffers in the normal setting (300/360 PPI input requested) versus best (600/720 PPI input requested) then you could get bad target patches but that is usually an indication of bad printer behavior and no base for profiling anyway.

In the past there were ICC profiles for different printer quality settings, I recall it for the Epson Stylus Pro 9000, about fifteen years ago. About ten/twelve years ago that disappeared for the printer brands and printers we use with their normal OS drivers and their semi RGB-device ICC profiling. My best guess is that compensations in the printer driver or hardware take care of possible color shifts nowadays and we can use just one profile for a media/printer combination in all quality settings. With RIPs as the driver and their CMYKetc ICC printer profiling it may be different, might differ between RIPs as well.

Hello Mike,

Reading the Auto Roll length announcement I thought 'not for me with a Z3200'. The video proofed that. But with the knowledge that the other feature Roll Paper Trimming worked more or less with the Z3200 PS3 driver I could not resist trying this one out with that PS3 driver. No Qimage warning produced so I guess you only tried the PCL3 driver and have the warning triggered for that driver or printer identity. I have the Z3200-PS revision A printer.

The first trial seemed to work right away and ignored even the Preview choice setting in the PS3 driver. Unexpected and no cheap paper on the printer for the trial so cancelled it immediately on the printer. I noticed that the max length of that Auto Roll was something like 1500 mm. I thought you added an arbitrary length for it as I have printed longer lengths. Exploring it more it seems to be the length of initially selected print page (custom or OEM) in the driver. I could extend that to 3480mm roughly by changing the initial print page to that length. 5000mm did not work. When Auto Roll Length is clicked on the driver defaults to Letter size internally. That Letter size does not show in Qimage but the Auto Roll Length shows.

When I go over the 3480mm length the Auto Roll Length feature does not split to two appropriate lengths for the images contained but multiple ones depending on the image sizes loaded on the print page. At least with about 14  400x500 mm images on a 903x3480mm print page and loading the 15th it goes for 7 lengths each filled with two images and one missing. Taking out one image it goes back to 14 images on 3057mm print page length, longer than set in the initial print page so there is more to gain I guess. Adding and deleting images in different quantities delivers odd combinations of print page lengths and not always the most economic image nesting. 2x 7 images on two print page lengths wastes more than 8 and 6 on slightly different print page lengths for the image sizes I mentioned. Could be some differences in the image sizes loaded. 

The 903x3057mm trial just ended with a print that length on cheap paper. This time the driver Preview choice worked also. It took an awful long time in processing to that Preview state though. For production somewhat shorter print page lengths processed after another gains time, processing done while the printer is already busy with the first length is a better choice.

So thank you Mike and please do not add a warning for that PS printer/driver model. I will explore the feature + that driver more.

The ability to open the driver dialog with driver defaults has been added to 2019.105.

Mike

Hello Mike,

Could it be that you also found a solution for added media presets in the Z3200 printer/driver?  This time I added the Photorag Ultra Smooth media preset and it stays in the Z3200 driver while Qimage mentions Unlisted [270]  as the "selected" media. I assume it would work without issues in printing and I guess you added something or this must be another hickup of HP software. Never seen it before.

15  Mike's Software / Qimage Ultimate / Re: Qimage suddenly prints landscape (as if paper was horizontal) on: January 13, 2019, 03:45:51 PM
From time to time I have a similar problem with my HP Z3200. Totally different printer and aimed at roll printing but nevertheless;  if the physical size of the roll width is even 1 mm less than what a 44" (1118mm) or 35" (914mm) roll width should be then a landscape printing page that is set at 1118mm wide will automatically turn to portrait mode on its way to the printer. The printer measures the width when the roll is installed and the driver adds the auto turning "feature". So I keep a bit of tolerence by using print pages 1mm less. Last week however that was even not enough and a stroke of 180mm wide and 1117mm long (several color proofs) was printed at the right side in the length of the Photorag roll. Does not make you happy. Careful QU intelligent nesting of the bigger prints on the remaining sheet made it less an issue.


So check the real sheet size and what has been set in QU or driver. Totally different printer though ..........


Met vriendelijke groet, Ernst
