Hello Mike et al

This morning I attempted the first printing using version QIU v115. It was a full size A2 image. The Canon Pro-1000 was set to its normal 1200 PPI and every other setting as usual.

QIU appeared to be sending a much greater amount of data to the printer (took longer) and when the printer started to print it ejected the page after about 1cm of printing. I cancelled and restarted both the PC and the printer. Repeated the procedure and same thing happened.

I reverted back to QIU v114 and the printer worked perfectly.

It seemed like v115 was sending 4x the data to the printer.

Regards

Peter

Peter,
Good morning, I guess I am the et al until Mike wakes up
In the meantime, I know he would appreciate all the information you could give him.
For example, what type of paper, at what quality setting in the driver, (a 1 or 2 or a 3)?
What did Qimage report as the Max ppi before you activated PRINT?
No Overdrive attempted

Have a look at the snap attached.
This box seems to be questionable. Mike has his set to OFF. Mine says weak but is grayed out.
What is yours set at, and after playing with the P 1000 driver here, it changes the information being sent to Qimage.

Thanks for the help.
Fred

Hello Fred.

Thanks for your response.

Canon Pro-1000. The quality is, as always, set to highest and default paper set to " .. Platinum" but actual paper Ilford Gold Fibre Silk with custom profile (ex Profile Prism).  "Overdrive" not (unable to be) set. PPI set at usual to the Max of 1200.

Within Windows the "Prevention of Print Data Loss" is set to "Off". However the same option when viewed within QIU is, as you describe, "On (Weak)" and greyed out. Why it is different, I have no idea.

Regards

Thanks again, Peter.
I know he will ask whether you downloaded and installed the XPS driver too, and if so, which are you using?
Fred

PS
Wants to know the exact OS you are using and also the (in QU: HEL)P (hold shift key) and click Analyze, and report memory

The previous 114 limited resolution to 720 max so 114 would have been printing at 600 PPI even if the max said 1200.  With 115, you get up to 1440 so 115 will honor your 1200 PPI setting and actually send data at 1200 PPI if that is your interpolation setting.  Whether or not you can actually print at that (4x) level of detail will depend on your system (OS and memory).

I tried an A2 print on the Pro-1000 set at 1200 and had no problem on my system.  I don't have the physical printer but I was able to turn on print preview in the driver and confirm that the driver got (and showed) the full A2.  The spooler showed 1.5 GB as the spool size.

So as Fred said, in Qimage go to Help, and then hold the shift key while you click "Analyze Current Settings".  That'll show us how much RAM Qimage has to work with.  That plus knowing what OS you are running may tell us something about why your system isn't handling all the data sent by Qimage.  Setting 115 to High (600 PPI) would result in an identical print to 114... but let's figure out where the memory bottleneck is on your system so you can make use of the new setting.

Regards,
Mike

and lets not forget to check the Raw and the enable boxes as per this article

Thanks Mike and Fred for your responses.

I have two PCs running Windows 10. One is a 32-bit stand-alone and the other is a 64-bit virtual machine (the one I normally use for printing). Both have 4 GB of RAM (and no other applications running). The Canon Pro-1000 is connected via WiFi.

I have been through both machines and reset the default printer properties within the Windows dialogue ensuring the "enable enhanced printing features" is checked, the spooling set to raw,  "prevent data loss" set to off and detail set to "Highest".

It seems that the "enable enhanced printing features" setting will not always "stick" and so I'm never able to see a print preview.

When I go to print full A2  at 1200 the QIU  queue shows about 1.5 GB. However when the data is sent to the printer, the Windows printing dialogue shows 0.98 GB after all data is sent.

I reverted to testing printing with A4 sheets.  With the "enable enhanced printing features"  set,  the A4 would not print completely. Unabled it does.

If I'm correct, an A4 at 1200 should have a spool size of about 370 MB. That is indeed what in showed on the QIU Queue.  When sent to the printer  the windows  printer dialogue shows about 189 MB when all data is sent. The complete page is printed.

Are the discrepancies in data size between the QIU queue and the Windows queue relevant or indicating an issue?

Regards

Peter

Hi Peter
The Enable box should be Unchecked and Mike will still want the results of {HELP.... ANALYZE with Shift key down}

Mike is the expert, but the 4 gig of ram sounds light.

One comment from me.... I had to wait quite an extraordinary amount of time before the print preview from the driver opened.
I was used to seeing it almost instantly from my Epsons.
I was about to give up on it, when POP.

Hello again Fred.

Yes, as I later noted, the "enable enhanced printing features" needed to be unchecked for the complete page to be printed (at least on my setup).

I may be wrong but I understood that the "enable enhanced printing features"  needs to be set to show the print preview.

Your screen shot of available RAM (?) is almost identical to what was displayed on my virtual PC machine which is normally used for printing.

Regards

Peter

My Pro-1000 driver is working normally even at the A2 size with enable advanced printing features checked or unchecked (doesn't matter).  The print preview shows the whole print and the windows spooler shows 1.5GB for the A2 print.  I'm on Win10 x64 with 8GB RAM.

On your setup you may be a bit handicapped on both systems with one being 32 bit and the other running on a virtual machine, both with only 4GB of RAM.  If you have trouble running it at 1200 PPI on your system(s), you may want to just bump it down one notch to 600 PPI.  QU is sending all the data but it has no way to know what the driver does with that data.  The next version will have some memory optimizations that reduce the spool size when 1200 PPI is not needed.  For example, if your original image is only 250 PPI at an A2 size, there is no need to interpolate to 1200 PPI: 600 PPI is more than enough, even if your setting is 1200 PPI.

Thanks for your reply Mike.

Would appreciate your opinion on my earlier query:

"If I'm correct, an A4 at 1200 should have a spool size of about 370 MB. That is indeed what in showed on the QIU Queue.  When sent to the printer  the windows  printer dialogue shows about 189 MB when all data is sent. The complete page is printed.

Are the discrepancies in data size between the QIU queue and the Windows queue relevant or indicating an issue?
"
 
For A2 sheets at 1200 both PCs show 1.5GB in QIU and 0.98GB  the windows  printer dialogue. Incidently the stand alone 32bit PC actually has only 3.1GB RAM. On the 64bit virtual PC I increased the RAM from 4GB to 5GB and there was no difference in the 1.5/0.98 result. Interestingly the Windows resources monitors (Memory TAB. tried on both machines) indicated a high level of "Hard Faults" while QIU was processing, whatever that means.

Will the spool size optimisation you mention for the next release be optional? It seems to me that the PPI setting, as is for sharpening, should be at least optionally under manual control. In my opinion it should be the user's choice like all other parameters?


Regards

Peter

So - for my Epson R 3000 the driver quality options go up to 1440x1440, and then even to 5760x1440 in what they call dpi.  But the QU Settings tab shows a max print resolution of 736 ppi. Obviously the overdrive would not affect these numbers but shouldn't there be some relationship between them that makes sense?

When I first installed my 1200 DPI Canon printer some months ago, QU showed max 600 for a while and then corrected. Obviously some action initiated a refresh.

It appears that you have borderless printing set with that expanded resolution. 720ppi is the normal "native resolution" for Epson printers. The higher quality values in the driver are printer ink dots per inch, not the same as pixels.
