Both the B9180 and Z3100 drivers have been updated recently and the new drivers are not compatible with old jobs and old saved setups from a year ago (or even a few months ago).  So if you load an old job, Qimage tries to restore the old driver settings into the new driver and some take, some won't.  For printer setups, the solution is easy: just use "Help", "Reset Printer Settings", restart Qimage and set the driver up manually (without loading any prior saved setups) and then save over your old setup file(s) with the new settings.  For jobs, it's a bit more difficult because when you load the job, the printer settings are loaded automatically and if it's an old job, the printer driver setup may not be compatible with the current driver you are using and that may foul up the driver.  Not really much you can do about that since HP made the new driver incompatible with the old.  Of course Qimage is the only program that will make this problem surface because no other printing software allows you to recall saved driver settings.  Can't have the problem if you don't have the feature.  Wink

Mike,

The Z3100 printer driver custom size settings never were restored with a Qimage recall. Not within firmware/driver version periods, not in periods overlapping more versions. That has been my experience. With the Epson drivers Qimage picks up the actual sizes, with the HP you have to give the custom size a name and save that and Qimage will restore it based on the name but that name may carry other sizes meanwhile. If you print a lot of different custom sizes this method of saving them with a specific name isn't working well and there were problems with the quantity of custom sizes possible + driver upgrades didn't install with more custom sizes saved. Why Qimage looks for the naming instead of the actual sizes in the HP driver is something I do not understand. Restoring the HP driver settings with a Qimage recall is a risky business anyway so I check the log file, restore Qimage's settings and then check the printer driver settings to see what is correct and what not.

Ernst,
I think what Terry is pointing out are issues that HP as yet hasn't resolved.
One, no banner mode to allow the user to make panos and extra large prints that exceed the driver limitations.
Two, and even more important, the propensity of the Z series to rescale prints and reposition prints on the paper *after* Qimage has sent the correct printing information.
There was another issue, whose details escape me at the moment, but it had to do with Qimage remembering the driver settings when exiting or when saving a printer setup.
I think the driver allowed some settings to be saved and sone were altered by the HP software which messed up the saving of the settings.
To the best of my recollection, Qimage conforms to certain accepted standards, be they Windows or drivers or email etc.
When the manufacturer of an item decides to run his product outside of the standards, there will be compromise, but certainly no blame on Qimage.

Best to you.
Fred

Fred,

The Banner mode was an issue with the plain Z3100 model as it limited the total length to be printed to 2.75-3.25 meter depending on the firmware/driver versions. The optional HPGL driver allows far longer lengths for that model. It wasn't and still isn't clear to me what lengths the Z3100-PS model could print. The Z3200-PS model that I have now has no length limitations with the PCL3 driver. I was the first to mention this length issue here and on other forums. But it is no issue anymore for someone buying a new Z3200. Not with Qimage and not with another application that doesn't know the Poster/Tiles/Banner detour to print longer lengths than the driver allows.

I have not encountered that second issue. There was an issue with the driver going back to its default size setting that can be annoying but I have written down more than once how that can be avoided. Same for the shorter length than roll width issue. In both cases Qimage adapts to what the driver gives in information and one becomes aware of that flaw at that stage. As written I have not seen a print that was wasted because the driver does it in the end differently to the data it gave Qimage.

Few of the printer driver settings are reloaded again if one recalls a job in Qimage. That is correct. There are ways to counter that, the Z models have a job log and one can repeat the job there too. The HP printing shortcuts can recall what the Qimage recall can't do on the HP driver. But I find this the major issue left with the Z models + Qimage because it takes away one of the best Qimage features.

At the time the issues were discovered (often by me) I asked Mike what was going on. Not having a clue who could be blamed. Mike's explanation that HP didn't go by the Windows rules was good enough for me. I have no knowledge at that level so I'm not going to point fingers.

I liked the simple email list structure. A filter on Thunderbird to bring relevant messages in one map, qimage and qstudio shared the same map. A filter on some contributors. One overview of all subjects. Reading the subject lines only and avoiding threads that are of no interest to me but with the knowledge they exist. I do not see that with the site forum which has the threads more pre-categorised so one may overlook an interesting topic or one has to plow through all the categories.

I understand there's no way back so yes move it all here.

Is there a way that you could make a Qstudio addition to the webpage that will only be visible to Qstudio subscribers recognised on their identity etc.?  Another URL to a page to log in would make it less attractive.

I know little about large format printers but from what I have read on the Q Yahoo group and here, is that HP users seem to have to go through loops to overcome HP's driver oddities, or are they bugs.  Roll Eyes
There seems to have been few problems with the other 2 manufacturers.
Terry.

The HP drivers have some oddities (mainly in cooperation with Qimage though) but after some driver and firmware upgrades I do not see them as a reason to avoid the HP models. The advantages of the HP Z models are: an absolute lower ink waste if compared to the Epson models and to a lesser degree to the Canon models. Best fade resistance of all pigment inks. Best B&W print result. Integrated spectrometer for calibration and profiling included in the price and on the Z3200 with improved profile creation software . Cheap and easily replaceable heads that still last a long time. Mine over two years now without replacement. Together with the Canon no clog issues like the Epsons have. In general little maintenance is needed. Latest Z3200 firmware includes a bar code printed on the roll used that indicates what is left on the roll (Canon alike) and more accounting features.

To get an overall view of wide format printer issues you better check the following forum and the list I moderate:

What surprises me is that you both could get good B&W print from an R1800-R800 model.
Unlike several other photo inkjet printers the R1800/800/1900 models do not have one, two or three extra grey inks to replace composite greys (CcMmY mixes) so are harder to keep neutral in their tone range and they will show more pronounced metamerism and later on more color shifting.
On the Digital B&W list the preference goes to printers with more grey inks, some custom inksets up to 7 inks. Of course they are seriously into B&W printing.

There's a third route to take:

Larger carts of the OEM ink can be less than 1/3 the price per ML compared to smaller carts of the same OEM ink. For example 0.23 Eurocent excl. VAT per ML  on a 775 ML cart compared to 0,78 Eurocent per ML excl. VAT on an 28 ML cart.  Bigger investment for some users but with all the advantages of using the right ink on the printer. Refilling carts from larger carts isn't difficult.

While I have used third party inks (early pigment) when the big printer companies had no suitable inks on the wide formats I wouldn't recommend it anymore. There were color shifts in the inks per batch that made consistency of job repeats difficult. The third party pigment inks had more pigment settling if not used frequently which also contributed to less color consistency and damper clogging. Dye inks are another category but I can not use dye inks for the jobs I have. There have been improvements in third  party pigment inks since I used them but the color inks are not matching the fade resistance of Vivera pigment ink for example. The last ink can even be used in Epsons which Paul Roark showed with the PK Vivera in an Epson 1400 (1.5 picoliter droplets). No clogs reported, neutral black, excellent fade resistance.

Where does one apply for membership of the Qimage Sudio mailing list on Yahoo ?

Studio user for some years I guess so that shouldn't be the problem.

Has anybody learned how to "trick" the HP Print Driver so that long prints can be run utilizing QImage Poster Feature? 

I cannot figure out how to get the "pages" to butt up against each other.  The closest I can get them is 3/8 of an inch.

I'm probably overlooking some obvious checkbox somewhere.

Thanks in advance.

MD Schulze


It  doesn't know a "Banner" mode so the Poster/Tiles method will not work, 1 cm white "seams" will appear between the tiles.

The extra HPGL 2 driver extension will allow longer than 275 cm prints on a Z3100. Some Z3100's cross that 275 cm on their own, some don't it seems. The Z3200-PS that I also have shows no problems with print 5 meters long and must go even longer.
