HP DJ550C problem?

#101261From: Mr. ChalleronMay 25, 1993 6:55 AM
I have a bit of a problem which I hope you can play detective with; it involves hardware and software conflicts, and of course all the suspects are accusing each other (except the butler, who admits he probably did it but doesn't know how): I recently bought an Amiga A4000/040, a Hewlett-Packard DeskJet 550C, and Softwood's Final Copy II Release 2; running this combination with the Amiga-supplied "HP_DeskJet" printer driver, I noticed that graphics colors were fine, but the black cartridge wasn't getting used unless I selected "grayscale" or "black and white" for the FCII "Graphics Printer" option. A call to Softwood said that this was a problem with the Amiga printer driver, and suggested I throw another 50 bucks at a "SuperDJ" (3d party) printer driver; instead I decided to lurk the HPPER Forum, and — lo and behold! — Hewlett-Packard had uploaded a new Amiga-specific printer driver for the "HP_DeskJet550C", which I DLed, unpacked, and installed (aware of the warning of HPPER Sysop Ted Dickens that the "driver is untested as I have no access to an Amiga"); sure enough, this driver took any true-graylevel information it found in FCII color graphics and used the black cartridge to spray it, which brought out new details I hadn't seen before. The problem is, when this driver "sees" an entire line of nothing but black text, it fades out at the far-right-side of the line, as if the black cartridge ran out of ink; interestingly, it doesn't matter _where_ the line had _started_ printing from: lines that had started printing from the right were also "faded" on the right. Again, switching FCII to "grayscale" solved the problem — however, it also printed the same text _visibly_blacker_. (Naturally, Softwood claims no responsibility.) Going back to the HPPER Forum I notice that there seem to be lots of mechanical problems with 550Cs; I posted a note describing my problems and Ted Dickens replied "we're working on it", but I'm not sure he really understands the problem, especially since he has no Amiga background. This past weekend my "Power Up" package finally arrived, and I've been playing with ADPro (when I haven't been arguing in the "tavern"), which is REALLY demanding of a printer, and I can't say I've noticed any problems with either the 550C itself or with the "HP_DeskJet550C" driver, except that the overall print-intensity seems to be dark (and intensity is, to read the messages on HPPER, one of the physical problems with the 550C); and still, when I print a combined-text-and-graphics file with FCII in "color graphics" mode, every time I hit all-black-text…. As our online CATS representative, you're my only hope, because you're probably the only person in the world who can examine every aspect of this problem. Do I: Assume I have a physical printer problem and take it back; pester Softwood for a Final Copy II "fix"; wait for HP to figure it out; or make a $50 sacrifice to the Gods Of Self-Publishing? I was _hoping_ there'd be an obvious oversight you could correct for me….

Mr. Challeron, I'm a little behind you. I bought a 550C some time ago to go with my 4000, and have used it with ADPro a fair amount, using the PrefPrinter section. Seems to work well, but as you report, things must be signifcantly lightened up for decent rendition. I, too, balked at actually paying for a printer driver, mainly 'cus this is a new idea to me. I keep thinking that SOMEone will eventually provide one as they always have before. But maybe this sucker's just too complex for that to happen (and have it be done well). So I was happy to see your message about the HP driver. When I get some time, I'll have to give it a try! Here's hoping we get some good answers from John, Karl

PMJI, What HP driver might this be? Andrew
#101551From: Karl SparklinMay 26, 1993 8:03 PM
Jeff Walker said that there is a driver that has appeared over in HPPeriph forum for the Amiga and DJ550C. It apparently has a few problems, but it's the only PD driver so far that mixes the black with the color cartridges. Karl
#101616From: Andrew PorterMay 27, 1993 12:44 AM
Karl, Oops, sorry to jump in. After I posted the message I realized that it was the 550C you were talking about, not the 500C that I just got. Thanks for getting back to me on that. Andrew

The trouble is you need more control over the output than a printer driver can give you. You need proper colour control and ink impurity compensation, you need decent dither methods that enable more colours to be simulated, you need control over brightness, contrast, gamma…. Essentially, you need a software package that provides these features, features which a printer driver alone cannot deliver. Jeff Walker – Just Amiga Monthly.
#101512From: Pete MilesMay 26, 1993 5:33 PM
…and that package is called Studio by Wolf Faust 🙂 Pete
#101550From: Karl SparklinMay 26, 1993 8:03 PM
Jeff, Does that mean that if I buy either the Studio "driver", the Creative Focus "driver" or the HP driver, I'm not going to be able to use ADPro's Prefprinter section? Karl
#101923From: Jeff WalkerMay 29, 1993 6:58 AM
Yes, with Studio you'll still be able to use ADPro's Prefprinter saver. But Studio comes with its own Prefprinter-type program that is at least as good. I think it's better, but then I have a vested interest in saying that so I guess you'd better ask someone else. 😎 Jeff Walker – Just Amiga Monthly.
#102072From: Karl SparklinMay 30, 1993 8:20 AM
Thanks for the reply. I wish someone here had both of them to state which does a better job. And I have yet to see an actual price for Studio listed anywhere. The feature list of Studio seems longer, but every time I shop that way, I wind up with something where I only use a few of the features anyway! Karl
#102056From: Jim SakladMay 30, 1993 1:49 AM
Karl – Well, my Super_DJC2 driver has recommended settings for working with ADPro's prefprinter, and it produces excellent copy in conjunction with ADPro. . . . . JimDoc, on AutoPilot
#102073From: Karl SparklinMay 30, 1993 8:20 AM
Jim, So you've done extensive printing with Super_DJC2 with the 550C and good paper, and like the results when mixing black with color inks? Do you have any experience with Studio? Are there any "features" that you don't like in Super_DJC2? Do you still have lighten graphics before printing them, so they don't come out so dark (like the standard 500C driver requires)? Thanks! Karl
#102634From: Wolf FaustJun 2, 1993 6:12 PM
Well, Karl, I'm the programer of Studio and so somehow maybe biased, but maybe some things that might be good to know about Super_DJ2 and Studio: 1. Studio is much more expensive than SuperDJC2. There are several reasons for it: – Studio comes with a real printed manual. Shiping this manual to the US costs $5 each! Add another $8 for printing and another $5 for writing… – Studio is much more powerfull than SuperDJC2. Sure this development has to be paid. You get a 24 Bit IFF (hopefully soon JPEG!) poster print-from-disk program, PageStream drivers and more. 2. I do work VERY closely together with HP and not without reason Studio supports the new DJ1200 and 4L since the 5 May (the day HP announced these new printers). I do take great care in writing nice PCL and Amiga code. 3. Studio main issue is quality, reliability and speed. You get the custom dither routines with Studio, allowing you to very precisly make use of the color adjustment setting. Here is where Studio shines compared to SuperDJC. For instance, you can adjust the brightness/colors of your output without loosing any color details while other DJ drivers usualy losse 1/3 of the color information. 4. There are many small things that usualy can go wrong using the Amiga printer device, applications and special printer drivers ("moving" pages, not well aligned dither matrices and more). Here again, Studio does fix most of these problems while others don't! Anyway, there are some limitations that affects both commercial drivers with the features like color output and dither routines: programs using their own dither and color adjustment routines usualy can't use the drivers functions (though, normaly you don't need them in these rare cases anyway). So far, programs that do not allow you to use the color adjustment of the drivers are: PageStream, TruePrint, ADPro's PrefPrinter Saver and the Studio picture printing program supplied with Studio drivers. In these cases the commercial drivers adjustment routines are of no use, though, every other functions (fast compression schemes…) are still working… — Wolf Faust, Am Dorfgarten 10, 6000 Frankfurt 50, Germany —
#102645From: Karl SparklinJun 2, 1993 9:06 PM
Thanks for the extra information on Studio, Wolf. A couple more questions, though: I have ADPro and am so far perfectly happy with its operation for image processing, so I have no need ( I don't think ) for another program of this type. So are you saying that if I use ADPro's PrefPrinter program, most of the impressive features of both Studio and SuperDJC are lost? Can I still adjust intensity? (Right now, I have to bump Brightness and Gamma up so that 550C images are not extremely dark.) Would the improved mixing of color and black cartridges be available through PrefPrinter? In other words, given the restriction of using ADPro's PrefPrinter, how do the two drivers stack up? Karl
#103118From: Wolf FaustJun 7, 1993 1:00 PM
No, you can't use most of the features that come with WB drivers when you use ADPro's PrefPrinter saver. All the color adjustment and dithering is done by ADPro and the color adjustment of the WB driver may only interfere (sometimes for good… sometimes for bad). But you can set things like page/margin settings/shingling/depletion and use these settings with ADPro. Also, these drivers use compression for fast output (as said, here is where Studio shines… it's even better than HP's own routine). Anyway, I don't think it's worth getting any commercial driver if you only use ADPro and no other Program with your DJ550C. Output may be slower and have some minor stripes… paper might be flooded because of lack of control over depletion… but unless you don't have problems… keep your money. That's my personal opinion as poor student… as programer I surely say get it 🙂 — Wolf Faust, Am Dorfgarten 10, 6000 Frankfurt 50, Germany —
#103158From: Karl SparklinJun 7, 1993 6:09 PM
Well, unfortunately, using ADPro doesn't allow me to use the black cartridge during color dumps. That's the main drawback, as I can't get dark blacks. Wish there was a driver I could throw in so that that would be taken care of without starting over with a different package. Thanks for your thoughts, Karl
#102788From: Jim SakladJun 3, 1993 10:56 PM
Karl – > …Super_DJC2 with the 550C and good paper, and like the results when > mixing black with color inks? At 25% shingling, and with good paper, you should be able to print graphics with black directly abutting color without problems, a good example being a color bar chart with the bars outlined in black. Ne experience with Studio. For doing ordinary "print" printing, I would like easier access to the printers features. Gerry Hull (author of the Super_DJ family) has a "DJ_Helper" program for this, but it needs to be updated for the 550/550C. DJPrint.REXX is useful, but also needs to be updated.
#101413From: Christopher TolmieMay 25, 1993 11:19 PM
Challeron, I have had similar experiences using the HPPheripheral Forum's printer driver for the 550C. Black letters dying on the right side, like the ink level running low in the cartridge, switch to grayscale or B/W and it prints fine and darker. I'm looking at Studio Printer. Chris
#101585From: Mr. ChalleronMay 26, 1993 11:34 PM
> looking at Studio Printer < I would too, except that I can't believe the Happy People at HP would be quite so willing to kiss off their "High Performance" braggadocio by saying, "Wulp, duh, gee, too bad we can't write a driver, hyuk, hyuk".
Mr. Challeron 76420,1471 I just happened to run across this string of messages and would like to clarify a few things. Going back to your original post, >>instead I decided to lurk the HPPER Forum, and — lo and >>behold! — Hewlett-Packard had uploaded a new Amiga-specific printer >>driver for the "HP_DeskJet550C", If you are referring to HPDJ55.lha, HP didn't upload this. I did. This was a Better_Than_Nothing driver I found on GEnie, which I used before purchasing Creative Focus's driver. I talked to the uploader to GEnie of that driver, he had no info on it except that he got it off a local BBS. Both of us uploaded the file in it's entirety, there was no other docs on it. I noticed the "faded out" problem too on my prints, this problem is from that driver. HP has no plans, as far as I know, to write a driver for the Amiga. A lot of Amiga users have asked them already, and I would think they would want to, considering the number of Amiga users who own or use their drivers, but alas, money talks… I uploaded that file so other Amiga users would have at least something to use. AmigaDos 3.0 may even have a better driver that this, I don't know, I'm using 2.04. Commodore, if anyone, should be the one making a 550c specific driver, in MHO. Though the way HP cranks out new printers, they might have a problem keeping up… I am just a Amiga enthusiast, I have no connnections to any of the companies you've mentioned in your post, except that I have purchased their products like yourself. I find the Creative Focus driver to be very good, and I was fortunate enough to purchase it for $35.00, the price he origanally offered for it. Dr. Gerald Hull, the author of the driver, seems to be a reasonable man, and he may be willing to sell you one for that price. (Then again, he may not.) He does address any bugs that people find, and has already released a rev for a problem with the magenta color on one of the intensity levels. He strikes me as being very serious about tech support of his products. Did you see AM550C.TXT in the HPPERI library? It is a text file I uploaded from Creative Focus describing the drivers capabilities. I think I also uploaded it in the AmigaUser forum, but I don't recall. I know next to nothing about Wolf Faust's Studio driver, but from the sounds of it, it too sounds very good. If I had heard of it first, I probably would of purchased it; but since I have Creative Focus's driver, I doubt if I'll get Studio. Either way, I believe the drivers would be worth the "sacrifice to the Gods Of Self-Publishing." I can see your resentment for discovering that more money must be spent in order to get the printer to work right; I was fortunate enough to be aware of the problem (of no driver from HP or Commodore) before I made my purchase, so it didn't seem so bad to me.

Studio is not "a printer driver", it is printing software. This includes printer drivers for ALL Hewlett-Packard printers (including the brand new DJs and LJs), plus preferences programs for those drivers that extend the Amiga's printing capabilities in a "legal" way — an extension to Workbench printer preferences in other words. On top of that you get a separate printing program that is very much TruePrint 24 (or the ADPro Prefprinter saver). It also supports most 24/48/64-pin Epson compatibles, and the Ricoh LP1200 in 400 dpi mode. Jeff Walker – Just Amiga Monthly.

Is Studio available in retail stores? I haven't seen it locally. …..Nancy In Edmonton, AB, Canada

Studio is distributed in North America through a new company called MacroSystem US. The name is not without reason. They mainly distribute the stuff produced by MacroSystem Germany ("Retina" graphic boards, VLab digitizer, Maestro audio digital i/o board, Studio…..). Because MacroSystem US is mainly a distributor not dealer, I'm sure you will find Studio in the retails stores once reviews are in the magazines (no store does buy/sell anything withough seeing a review first). And if the reviews are as good as the german once, they surely do… MacroSystem US will hopefully soon be available on CIS with it's own vendor forum. Anyway, I'm allays here for Studio users in case of trouble… Here's the adress, but you should ask you dealer. Usualy they have a much cheaper price than the official distributor: MacroSystem US 17019 Smugglers Cove Mt.

Thanks very much for your reply; I didn't know "HP_DeskJet550C" was itself a 3d-party product. I may wait for C= anyway; most of my DTP stuff is grayscale, very little color (and I can always CYMK-separate _if_ I ever fall into a big contract). Hell, if the workload gets THAT good, I may invest in a different printer altogether. 😎
