Setup & Installation / Re: Canon MG7550 issues

Hi Pete,

Attached is a zip with 3 PPD files for the sameprinter.
One from an older Mint Linux with Cups 1.4.8 and the downloaded Canon driver, called MG7500 series, USB attached printer. Couldn't get the printer over the LAN working so far with this.
One from a newer Mint Linux with he Cups 1.7.2 driver and ppd, LAN attached printer.
One from OS/2 Cups 2.0.0 (Paul's), LAN attached printer.

I hope this helps,

Regards, Mat

One more data item:

I was able to test in Mint Linux 17.1. I used the standard install to add a printer, to my surprise it saw the printer on the LAN. I let it install it, it used the DNS-DS protocol (keywords: zeroconf, bonjour, avahi).
This Mint uses Cups 1.7.2 , Gutenprint 5.2.10-pre2, and I selected printer MG7100 . It didn't allow me to select cassette 1 either. It printed the test page not quite OK, missing most of the border. I then attempted to print my standard reference print from www.colour-science.com, with 4x6 paper in the printer's cassette 1, with Mint's gthumb. When I selected that Glossy paper, and set the printer source to 'printer default' , it came out properly from cassette 1, although a bit dark.

I checked the Mint Cups backend directory, and it indeed uses dnsds. The printer tool from that Mint even showed ink levels (don't know how accurate).

Our Cups 2.0.0 doesn't have a dns-ds backend available, and I cannot find it under it various names on either Hobbes or this site. I have no idea how difficult this would be to port. The Ahavi diagram on Wikipedia didn't look simple.

Even if it were available, you'd be dependent on Cups translating the OS/2 4x6 request to the proper printer cassette. No easy fix, I think.

Regards, Mat

Hi Pete,

Thanks, I won't try that. My guess that now that that printer asks you to tell it which paper is in which cassette,  the official Canon drivers now simply ask the printer what it has and adapts the users available choices accordingly. I'm not sure if that would be available using bjnp. I hope I'll have time today to test the Canon drivers on Linux Mint 17.1, and see if I can get to cassette 1 from there.

Anyway, finding out how to control paper source should be a reverse-engineering job of e.g. the USB or BJNP protocol. I think I read that Wireshark has some support for the protocol. That would be right in my ballpark, but time....

Time is short here as well, at least until December.

Regards, Mat

I have been able to test with a Windows and the sample photo paper that came with the printer.

If you initially look at windows, you see also just one cassette, nr 2. If you print on 10x15 cm for the photo, then the cassette changes to 1, presumable because I registered that paper for that cassette at the printer, and Windows queries the printer (via the LAN).

I attempted to print from OS/2 a photo using PMView, it didn't give me a different cassette after selecting 10x15. I did initially get a forms mismatch in the OS/2 spooler, but this can be fixed by enabling in the printer driver properties (not the job properties) in the Options tab "Override form mismatch" . Then the photo went to the printer, but it still wanted to print on the bottom cassette with A4. Better but not quite there yet, I don't really want to change the paper in the bottom tray just for a photo.

Hi Pete,

From looking at the Canon website, the MG7150 also has two cassettes, I don't know what changed between the two.
Under Linux, using Cups 1.4.8 with the binary Canon driver, the paper size is set up the same in Cups as under OS/2, and if I print a Linux Cups test page the printer does not complain. I guess I ought to look at the datastream to the printer and see what difference there is, maybe they translate the Cups setting into something different.
The ppd file Canon uses on Linux is so different from the OS/2 (Cups 2.0.0) one, that I don't dare importing it.
Do you have a windows to test with? Does the cassette 2 appear there?

Hi Alex,

thanks, but I am using Cups, and it also has the problem if I print a Cups test page, where I can see the media as being "media=iso_a4_210x297mm" . I wonder if it hasn't more to do with the paper type than the size. In Cups it is set to "plain paper", and if I set the printer to the English menu it is the same "plain paper", but it still has the problem.

Hi,

First, many thanks to Pete for his instructions on how to get the 7550 to work with cups on the network. I've done this successfully on both my live and test partition.

I have two issues with printing:
- The printer (using the MG7150 model in Cups which is very similar) has 2 paper cassettes. I can only address cassette 2 (bottom one, A4 paper), and the CD. I cannot address cassette 1, which normally hold envelopes or photo paper. On a Mint Linux system with Cups 1.4.8, I installed the Canon drivers, they work fine and have the same problem. I cannot test here with the Windows package that comes with the printer to see if cassette 1 can be used. Has anyone suggestions?

- Whenever I print A4, the printer complains about it not being the same paper. Obviously both PC and printer have been setup for A4. I've disabled the warning for now, but what does the printer look at for this? I've set the menu language to Dutch, I cannot imagine this would be related. Suggestions?

Thanks, Mat
