Hello Perry. I just purchased the Sharp JX 100 scanner and am very impresssed with your software. Everything looks terrific. I have a question though, actually two since you migh not have seen my other one on amiga.hdwe. First, in the scanner manual it states that the JX 100 can achieve resolution up to 400 DPI but it's really a psuedo type of mode in that it is not really 400 DPI but somehow the software or firmware does somwething to get the (seemingly) extra resolution. My question is: Is this anything that you can do in your Scanlab software to achieve these results, even 300 DPI would be fine so that I can get 300 DPI output on the laser at full scanned size? Are you working on an update to the scanlab 100 software? The secone question is about your dual serial board. I now need another serial port to hook up the scanner to permanently. I have seen yours for $299 and one from Checkpoint Technologies for $199. The question is: Why is yours $100 more? (actually a couple of other questions also). How easy is it adapt the software to use the serial board? WIll it go fast enough to keep up with the JX Scanner at 115K BPS? Thank you for any help you can give.

I don't know how the scanners send the data up to the computer, but I'm
surprised that they don't compress the image. After all, anything with a
lot of whitespace is not going to need 1 Mbyte+ for a compressed image.

My question is: Is this anything that you can >do in your Scanlab software to achieve these results, The JX-100 can basically replicate pixels as at scans. The basic optical resolution of the device is 200 DPI. When scanning at the 400 DPI ``mode'' you're just getting every pixel four times. >even 300 DPI would be >fine so that I can get 300 DPI output on the laser at full scanned size? This impression is very common but is mistaken. The mistake is that you are counting dots as dots even though the JX-100 delivers dots with far more information than your printer can print. To Wit: At 200 DPI in gray scale the JX-100 delivers 64 true shades of gray which is equivalent to 1600 DPI of monochrome dots. That is, a monochrome printer such as your laser printer will combine an 8 by 8 grid of black or white dots together to approximate the shading of one JX-100 dot. Therefore, a 200 DPI gray scale scan is more than enough resolution to overdrive any 300 DPI laser printer. It's all in the dots, man. >Are >you working on an update to the scanlab 100 software? Yes, it is called The Art Department. Seriously, ScanLab/100 is marketed directly by Sharp Electronics. A mandate for improvements to ScanLab/100 must come from them as they pay the bills. >The secone question is >about your dual serial board.

Actually, the list price of the Dual Serial Board is $249 not $299. I believe the list price of the CheckPoint board is also $249 but I could be mistaken. Apart from that, they are both fine boards. >(actually a >couple of other questions also). How easy is it adapt the software to use the >serial board? WIll it go fast enough to keep up with the JX Scanner at 115K >BPS? Thank you for any help you can give. In order to go as fast as we go in the scanner software, we must go directly to the hardware. Even allowing vertical blank interrupts was enough to cause missed characters at 115,200 baud (which is the scanner's top operational speed). It would not be feasible to support expansion serial boards since each would require its own unique driver code inside the scanner program since we must go directly to the hardware of each board.

Im interested in getting a scanner <although not too anxious right now.> Approximately how much do good color or b&w ones cost for the A500? What soft- ware would I need to convert the images to IFF ones, or are they atomatically made into IFF images? thanks in advance. Also where can I get a printer driver editor or a printer driver for an okidata 180 <similar to the 120>??? i need one in the next month or else im up shits creek. Thanks in advance again. s ------------------------------------------------------------------------------- o o | This Space For Rent // << md41@cunixb.cc.columbia.edu >> | Amerikkka's Most Wanted \X/ /> <\ | I made up my own mind, now I want a Tshirt ------------------------------------------------------------------------------- Chi Omega Rho Fraternity.
